The FDA issues guidance on animal antibiotics–voluntary, alas, but still a major big deal

I was in Washington DC last week when the FDA announced  that it was taking significant steps to address antibiotic resistance, a problem caused by overuse in raising animals for food.

The FDA called on makers of animal antibiotics to:

  • Voluntarily stop labeling medical important antibiotics as usable for promoting animal growth or feed efficiency (in essence, banning antibiotics from these uses).
  • Voluntarily notify the FDA of their intent to sign on to these strategies within the next three months.
  • Voluntarily put the new guidance into effect within 3 years.
  • Agree to a proposed rule to require a veterinarian’s prescription to use antibiotics that are presently sold over the counter (the proposal is open for public comment for 90 days at www.regulations.gov.   Docket FDA-2010-N-0155).

Voluntary is, of course, a red flag and the Washington Post quoted critics saying that the new guidance falls far short of what really is needed—a flat-out ban on use of antibiotics as growth promoters.

  • Consumers Union is concerned about the long delay caused by the 3-year window.
  • CSPI is worried about all the loopholes.
  • NRDC thinks the FDA is pretending to do more than it’s really doing and “kicks the can significantly down the road.”
  • Mother Jones points out that the meat industry can still “claim it’s using antibiotics ‘preventively,’ continuing to reap the benefits of growth promotion and continue to generate resistant bacteria.”
  • Civil Eats reminds us that the Pew Commission on Industrial Farm Animal Production (on which I served) recommended a ban on nontherapeutic use of all antibiotics.

Yes, the loopholes are real, but I view the FDA’s guidance as a major big deal.  The agency is explicitly taking on the antibiotic problem.  It is sending a clear signal to industrial farm animal  producers that sooner or later they will have to:

  • Stop using antibiotics as growth promoters.
  • Stop using antibiotics indiscriminately, even for disease treatment.

I think the FDA is dead serious about the antibiotic problem.  If the FDA seems to be doing this in some convoluted fashion, I’m guessing it’s because it has to.  The FDA must not have been able to find any other politically viable way to get at the antibiotics problem.

I see this as a first step on the road to banning antibiotics for any use in animals other than the occasional treatment of specific illnesses.

As the New York Times puts it,

This is the agency’s first serious attempt in decades to curb what experts have long regarded as the systematic overuse of antibiotics in healthy farm animals, with the drugs typically added directly into their feed and water. The waning effectiveness of antibiotics — wonder drugs of the 20th century — has become a looming threat to public health. At least two million Americans fall sick every year and about 23,000 die from antibiotic-resistant infections.

Still not convinced antibiotics are worth banning for promoting growth?

The best explanation is the Washington Post’s handy guide to the antibiotic-perplexed.  Here, for example, is its timeline of development of microbial resistance to antibiotics.  The bottom line: the more widespread the use of antibiotics, the greater the onset and prevalence of resistance.  And it takes practically no time for bacteria to develop resistance to antibiotic drugs.

USDA asks for public input on how to communicate “agricultural coexistence”

I am indebted to Farm Futures for the heads up about the USDA’s just-published request for public input on what it calls “enhancing agricultural coexistence.”

Agricultural coexistence, the USDA says,

refers to the concurrent cultivation of crops produced through diverse agricultural systems, including traditionally produced, organic, identity preserved (IP), and genetically engineered crops.  As the complexity and diversity of U.S. agriculture increases, so does the importance of managing issues that affect agricultural coexistence, such as seed purity, gene flow, post-harvest mixing, identity testing, and market requirements.

My translation: The USDA wants producers of traditional crops and organic foods to stop complaining that GMOs are contaminating their crops, and producers of GMO crops to stop complaining that they get prosecuted if they try to save seeds from year to year.

The USDA explains that it is doing this in response to recommendations from its Advisory Committee on Biotechnology & 21st Century Agriculture.  This committee recommended actions to promote agricultural coexistence in five areas:

  1. Potential compensation mechanisms
  2. Stewardship
  3. Education and outreach
  4. Research
  5. Seed quality

How come the USDA is collecting input on #3 rather than the far-more-likely-to-be-controversial #1 and #2?

Early in 2011, I wrote about USDA Secretary Tom Vilsack’s use of Cold War rhetoric to promote détente between growers of organic and GMO foods.  I pointed out that while the USDA had no intention of backing down on support of GM agriculture, it was at least recognizing the threat to organic production.

I noted that the USDA was unlikely to get very far with this initiative because so many farm groups representing industrial agriculture so strongly objected to Vilsack’s coexistence proposal.  The groups argued that coexistence could “adversely impact all producers of biotech crops, as well as the integrity of the American agriculture system.”

If you can’t do anything about underlying structural problems, try communication.

Have something to say about what it will take to support all systems of agricultural production?  Now is a good time to weigh in.

Pew Commission on Industrial Farm Animal Production: Update

I was a member of this Pew Commission, which produced a landmark report in 2008: Putting Meat on the Table: Industrial Farm Animal Production in America.

Our report’s conclusion: The current system of raising farm animals poses unacceptable risks to public health, to communities near Confined Animal Feeding Operations (CAFOs), and to the environment.

Our key recommendations:

  1. Ban the nontherapeutic use of antimicrobials in food animal production.
  2. Define nontherapeutic use of antimicrobials as any use in food animals in the absence of microbial disease or documented microbial disease exposure.
  3. Implement new systems to deal with farm waste.
  4. Phase out gestation crates, restrictive veal crates, and battery cages.
  5. Enforce the existing environmental and anti-trust laws applicable to food animal production.
  6. Expand animal agriculture research.

Recently, the Johns Hopkins Center for a Livable Future (CLF) did an in-depth analysis of what has happened with these recommendations.  Its dismal conclusion: The problems have only gotten worse.

Many hoped the release of the report, which occurred within a year of a change in the administration, would help trigger a sea change in the federal government’s approach to regulating the food animal production industry…Early administrative appointments to top regulatory posts held promise for meaningful changes.

CLF’s review of the policy-landscape changes in the five years since the release of the report paints a very different picture. Contrary to expectations, the Obama administration has not engaged on the recommendations outlined in the report in a meaningful way; in fact, regulatory agencies in the administration have acted regressively in their decision-making and policy-setting procedures.

In addition, the House of Representatives has stepped up the intensity of its attacks on avenues for reform and stricter enforcement of existing regulations, paving the way for industry avoidance of scrutiny and even deregulation, masked as protection of the inappropriately termed “family farmer.”

The assaults on reform have not been limited to blocking policies…Instead, the policy debate…has shifted to the implementation of policies such as “ag-gag”, agricultural certainty, and right-to-farm laws, all of which are designed to further shield unsavory industry practices from the eye of the public and the intervention of regulators.

This week, some of the Commission members answered questions from ProPolitico reporter Helena Bottemiller Evich.  Ralph Loglisci reports in Civil Eats on that meeting and his conversation with former Pew Commission director Robert Martin, who is now the Center for a Livable Future’s Director of Food System Policy:

I think issues are going to drive change at some point. You’ve got this big group of people who want to see change. The problems of antibiotic resistance are worsening–the problems of 500 million tons of (animal) waste we produce each year are worsening and the ground in many areas of the country is really saturated with phosphorous. You can’t transport the material, so you’ve got to disperse the animals. So, the problems are reaching really a crisis point. So that could really force action too.

Is there any hope?  It sounds like things will have to get worse before they get better.  But how much worse?

I wish there were better news.  Food safety, animal welfare, and environmental advocates: get together and get busy!

Soda tax controversy goes international

My monthly first Sunday Food Matters column in the San Francisco Chronicle:

Q: I hear that the Mexican government wants to increase taxes on sodas as a way to fight diabetes. The soda industry persuaded voters to defeat soda taxes in Richmond and El Monte last year. Won’t it do the same in Mexico?

A: It might. I’m just back from a lecture trip to Mexico City where I heard plenty about the proposed soda tax and the industry’s response to it.

Last month, the Mexican government proposed an additional soda tax of one peso (about 8 cents) per liter. The idea is to raise $1.5 million per year while discouraging soda consumption, thereby helping to reduce the country’s high prevalence of obesity and Type 2 diabetes.

Mexicans drink lots of soda. By some estimates, average per capita consumption is 50 gallons a year, the highest in the world. It’s no coincidence that more than 70 percent of Mexicans are overweight or obese, and around 15 percent have Type 2 diabetes, a prevalence that terrifies health officials. This type of diabetes, if undiagnosed and untreated, can lead to blindness or foot amputations.

‘Nutrition transition’

Mexico is a classic example of a country in “nutrition transition.” As the economy improves, people increasingly buy high-calorie ready-made foods, put on weight, and raise their risk for diabetes. Meanwhile, the poorer segments of the population continue to experience high levels of stunting, iron-deficiency anemia and vitamin A deficiency.

This makes obesity a relatively new problem in Mexico, one widely understood to result from the introduction of processed foods – especially sodas – into the Mexican food market.

I could easily see how deeply sodas are embedded in Mexico’s food culture. Sodas were advertised and available everywhere. And they come in enormous three-liter bottles that cost less than the price of bottled water – only 17 pesos ($1.35) each. Clean water is not always available, making sodas the easy choice.

Sodas are cheap because Mexico grows its own sugarcane and sells it at market prices. We, however, artificially support the higher price of U.S. sugar through tariffs and quotas. That’s why our sodas are made with high fructose corn syrup. We subsidize corn production so corn syprup costs less than sugar.

Some people think cane sugar tastes better than high fructose corn syrup, although controlled taste tests don’t always back this up. It’s ironic that U.S. supermarkets now carry, at highly inflated prices, Mexican Coca-Cola sweetened with cane sugar.

Industry efforts to defeat the Mexican soda tax have been ferocious, just as they were in Richmond and El Monte last year. Producers argue that if the tax really does decrease consumption, it will cause hundreds of thousands of jobs to be lost.

I saw a newspaper advertisement from the Mexican Beverage Association that not only attacked the science relating soft drinks to obesity, but extolled the health benefits of sodas: “Sugar is nutritious; it’s a carbohydrate. Carbohydrates are essential for life. Sugar is indispensable for the brain. Soft drinks hydrate and bring energy.”

An ad from the sugarcane industry also threatened job losses – “The tax will generate unemployment and discourage productivity and investment” – and noted that workers and the poor will bear most of its burden.

The big questions

As with any such initiative, the big questions are whether the tax is likely to reduce soda consumption, obesity and diabetes, and whether the revenue will be used for widely beneficial public health purposes. Mexico’s Congress will have to address these questions when it votes on the tax in the weeks ahead.

In the meantime, a coalition of consumer and health groups, in part funded by Bloomberg Philanthropies, has been putting posters in subway stations that illustrate the amounts of sugar in soft drinks. The groups are actively advocating for the soda tax and for using its funds to provide free potable water in schools – something that does not now exist. But TV stations have refused to carry their ads for fear of losing soda advertisers.

Like their U.S. colleagues, Mexican public health authorities are searching for effective ways to reverse obesity trends. Sugary drinks are an easy target. Taxing them might happen despite industry opposition – especially if the funds are earmarked for clean water.

Daily News editorial: The Judge Drank Corporate Kool-Aid

Politics, they say, makes strange bedfellows.  I can understand why the New York Times would do a front-page investigative report on how soda companies engage minority groups as partners while slamming Mayor Bloomberg for overreaching with his soda cap initiative.

But can someone please explain the Daily News?   Here’s yesterday’s front page:

This was followed by two pages of “Soda plan struck down; our cups runneth over” and other gleeful responses to the judge’s soda cap decision.

But then there’s this astonishing editorial.  Explain, please.

Judge drinks the Kool-Aid

In putting Mayor Bloomberg’s soda ban on ice, Manhattan Supreme Court Justice Milton Tingling did a huge disservice to the health and welfare of hundreds of thousands of New Yorkers.

Tingling concluded that the prohibition against selling sugared beverages in containers larger than 16 ounces was both arbitrary and beyond the authority of the Board of Health, which approved the regulations.

The only thing arbitrary here was Tingling’s ruling. More, the judge was the only party who was guilty of overreaching.

At heart, he simply substituted his judgment as to sound public policy for the board’s — an action that’s beyond a judge’s proper purview.

Most amazingly, Tingling held that the board had acted rationally in voting the portion cap as one method of trying to rein in the city’s epidemic of obesity and obesity-related diseases.

He bought the indisputable premise that the board was right to draw connections among high soda consumption, obesity and diabetes, which are debilitating New Yorkers young and old.

But then the judge threw that over by stating the obvious fact that the board did not have the power to ban supersized sugar drinks everywhere, only in establishments regulated by the Health Department.

Because the public could get a 32-ounce cup at, say, a 7-Eleven, but not at restaurants, he in effect deemed the ban to be an ill-designed contraption destined to fail. But who is Milton Tingling to say that? No one.

His fundamental error was to consider the regulation from the point of view of vendors who were hoping to get out from under it.

Those covered by the ban claimed they were the victims of capriciously unequal treatment and shifted Tingling’s concern away from the pressing rationale for a regulation that would have been broadly applied.

There’s nothing arbitrary about the consequences of drinking large quantities of sodas and other overly sweetened beverages.

The correlation in certain communities among consuming soda, becoming obese and contracting related diseases are certain.

The neighborhoods with the highest obesity rates — Harlem, the South Bronx, central Brooklyn — have the largest percentages of people who are likely to drink more than one sugar-sweetened beverage each day.

All too predictably, people in low-income areas such as Bedford-Stuyvesant and East New York, Brooklyn — places where soda consumption is highest — are four times as likely to die from diabetes as residents of the more affluent upper East Side, where people generally consume far fewer sugary drinks.

No matter.

Tingling attended to the arguments of businesses looking after their own financial interests over the demands of public health — while at the same time declaring that the Board of Health is barred from taking into account the substantial economic costs generated by obesity.

Ultimately, Tingling bought into the all-or-nothing argument — the same line of thinking that killed an earlier Bloomberg proposal that would have barred people from buying sugary sodas with food stamps.

The U.S. Department of Agriculture killed that experiment, asserting that it would be unfair and unproductive to target only a limited population in such a test. So Bloomberg tried to go bigger, and Tingling shot him down.

If bringing down a serious threat is a rational goal, as Tingling wrote, then you do it as best you can, even incrementally.

A halfway measure is better than no measure and is certainly not arbitrary.

Bloomberg vows an appeal.

Here’s hoping that Tingling’s judicial superiors recognize that pursuing public health is not just rational, it’s imperative. 

Afterthought: compare this to the Times’ editorial:

There are better ways for Mr. Bloomberg to use his time and resources to combat obesity.  One is to push Gov. Andrew Cuomo and the State Legislature to impose a penny-per-ounce tax on sugary drinks…the big-drinks ban was ill conceived and poorly constructed from the start.

New books take a fresh look at public health

If I were teaching public health nutrition right now, here’s what I’d want students to read:

Geof Rayner and Tim Lang, Ecological Public Health: Reshaping the Conditions for Good Health, Routledge Earthscan, 2012.

Our case is that public health is an interdisciplinary project, and not merely the preserve of particular professionals or titles.  Indeed, one of the themes of the book is that public health is often improved by movements and by people prepared to challenge conventional assumptions and the status quo…In these cynical academic times, when thinking is too often set within narrow economistic terms—What can we afford? What is the cost-benefit of health action?—and when the notion of the ‘public’ is often replaced by the ‘individual’ or the ‘private,’ this book offers an analysis of public health which is unashamedly pro bono publico, for the public good.

David Stuckler and Karen Siegel, eds.  Sick Societies: Responding to the Global Challenge of Chronic Disease, Oxford University Press, 2011.

Sick Societies argues that we are building environments that are poorly designed for our boides: we create societies where tobacco, alcohol, and foods containing high levels of salt, sugar, and fats are the easiest, cheapest, and most desirable choices, while fruits, vegetables, and exercise are the most expensive, inaccessible, and inconvenient options.  The rise in chronic diseases is the result of a model of societal development that is out of control: a model that puts wealth before health.

Wilma Waterlander, Put the Money Where the Mouth Is: The Feasibility and Effectiveness of Food Pricing Strategies to Stimulate Healthy Eating, Vrije Universiteit, Amsterdam, 2012.

This one is for policy wonks and change agents.  This is Waterlander’s doctoral dissertation done as a published book but it is written clearly and forcefully.  Her conclusions:

The studies presented in this thesis show that the healthy choice is the relatively expensive choice; that price fundamentally affects food choice and may even form a barrier for low SES consumers in selecting healthier foods.  These findings make pricing strategies a justifiable tool to stimulate healthier choices…making healthier foods cheaper was found to be the most feasible pricing strategy to implement.

Where are we on the farm bill and where should we be?

The best explanation of what’s happening with the long-delayed 2012 farm bill comes from the National Sustainable Agriculture Coalition.  In September, it produced a still very much relevant Q and Aon the topic. The 2008 farm bill expired without being renewed.  If Congress does not act soon, farm policy will be in big trouble. Here are some brief excerpts:

What is the relationship between the farm bill and the automatic budget cuts scheduled for January 1? The new farm bill, when and if it becomes law, will cut more spending from farm bill programs overall, on a net basis, than the automatic budget cuts scheduled to begin on January 1 under the requirements of the Budget Control Act of 2011…Whether Congress postpones the start date for automatic cuts or in other ways amends the Budget Control Act when it returns to DC after the elections is one of the biggest issues hanging over the lame duck session.

What are the farm bill choices that Congress has during the lame duck session? There are two theories about what happens next.  In one, the House returns after the elections and finally brings its bill to the floor, passes the bill with amendments, the House and Senate versions then get reconciled in a farm bill “conference” committee, and a melded final bill is…sent to the President for his signature — all within the three to five weeks of the short “lame duck” session. In the other theory, Congress returns after the election and works out the details of a bill to extend, with some modifications, the 2008 Farm Bill until a date in the spring, summer, or fall of 2013.  Under this scenario, the new session of Congress that begins in January (and lasts for the next two years) will start the five-year farm bill process all over again, with both House and Senate Agriculture Committees formulating a new bill that will then go through the entire legislative process all over again….

Could a new Congress next year simply revert to the farm bills passed this year? No, not exactly.  Legislation does not carry forward from one Congress to the next.  The process must start all over again, with bills introduced, markups in Committee, and votes on the floor of both bodies… That said, if the leaders and members of the Agriculture Committees (some of whom will be new next year) decide to bring forth and approve essentially the same bill they produced in 2012, that is an option open to them.  But it still must go through the normal process and be subject to amendments and voting all over again.

What is the best path forward? There can be little doubt that the best path forward is for Congress to finish its work on the 2012 Farm Bill in 2012.  That will mean getting the House bill to the House floor very quickly when the lame duck session begins, but leaving plenty of time for debate and amendments.

Sigh.  The Q and A explains the consequences of congressional inaction.  The elephant in the farm bill, of course, is SNAP (formerly food stamps), which accounts for roughly 80% of farm bill spending at a time when budget cuts head the congressional agenda.  The most recent data show SNAP participation—and, therefore, costs—to be at a record high: more than 47 million.

As to what to do about the farm bill: The Atlantic has just posted a speech by Wendell Berry on “the 50-year farm bill.”

I have described the need for a farm bill that makes sense of and for agriculture — not the fiscal and political sense of agriculture, as in the customary five-year farm bills, but the ecological sense without which agricultural sense cannot be made, and without which agriculture cannot be made sustainable. “A 50-Year Farm Bill,” which has been in circulation now for more than three years, is a proposal by The Land Institute in Salinas, Kansas, with the concurrence of numerous allied groups and individuals. This bill addresses the most urgent problems of our dominant way of agriculture: soil erosion, toxic pollution of soil and water, loss of biodiversity, the destruction of farming communities and cultures. It addresses these problems by invoking nature’s primary law, in default of which her other laws are of no avail: Keep the ground covered, and keep it covered whenever possible with perennial plants.

We need a farm bill that promotes health–of people and the planet.  Buried in the messy politics of the farm bill is an opportunity to do much good.

Will Congress take it?  Only if we insist.

School lunch rules caught up in politics

Here’s my monthly (first Sunday) Food Matters column for the San Francisco Chronicle.  For links to appropriate resources and what to do to defend the new standards, scroll down to Friday’s post.

Nutrition and public policy expert Marion Nestle answers readers’ questions in this column written exclusively for The Chronicle. E-mail your questions to food@sfchronicle.com, with “Marion Nestle” in the subject line.

Q: Can you please explain to me why the USDA is restricting the number of calories in school lunches. It’s bad enough that school food is so awful that the kids won’t eat it. Now are they supposed to go hungry as well?

A: I don’t know whether to laugh or cry at a question like this or at the uproar over the U.S. Department of Agriculture’s new nutrition standards. As Comedy Central‘s Jon Stewart pointed out in his not-to-be-missed commentary on Sept. 27, if kids aren’t eating the food because they hate it, the calorie limits hardly matter. And if kids are hungry, the remedy is simple: Eat the food.

The new lunch standards hardly call for starvation rations. Kindergarteners through fifth-graders get up to 650 calories. The maximum is 700 for kids in grades six through eight, and 850 for high schoolers. All kids can have extra servings of vegetables. This ought to be plenty to get most of today’s kids – sedentary, underactive and prone to obesity as they are – through any school day.

Let’s face it. This uproar has nothing to do with school food. It has everything to do with election-year politics.

Some Republicans view school meals as convenient generator of emotional opposition to the incumbent president.

You don’t believe me? Take a look at the “No Hungry Kids Act” introduced by Reps. Steve King, R-Iowa, and Tim Huelskamp, R-Kan., both members of the House Agriculture Committee.

Their act would repeal the USDA’s hard-won nutrition standards and prohibit upper limits on calories. As King explains, this is to undo “the misguided nanny state, as advanced by Michelle Obama’s Healthy and Hunger-Free Kids Act.”

You can’t make this stuff up.

Let me briefly review where these standards came from. In 2004, Congress required school districts to develop wellness policies, but left the details up to the districts. In part to resolve the resulting inconsistencies, Congress asked the USDA to develop new nutrition standards. In turn, the USDA asked the Institute of Medicine to study the situation and make recommendations.

The institute’s 2009 report called for aligning school meals with the Dietary Guidelines for Americans by increasing fruits, vegetables and whole grains, but reducing saturated fat, sodium and calories. It suggested encouraging students to try new vegetables by establishing weekly requirements for various kinds, but to limit starchy vegetables like potatoes to one cup a week.

In 2010, Congress passed the Healthy, Hunger-Free Kids Act which required the USDA to set nutrition standards for all food sold and served in schools, not only at breakfast and lunch, but also at any time during the school day. The USDA used the institute’s report as a basis for its proposals.

These, you may recall, got the USDA in trouble with lobbyists for businesses that supply French fries and pizza to schools. The Senate intervened and amended the agriculture spending bill to say that none of its funds could be used to “set any maximum limits on the serving of vegetables in school meal programs” or “require crediting of tomato paste and puree based on volume.” The results include no weekly limits on French fries; a dab of tomato paste on pizza now counts as a vegetable serving.

With these allowances in place, the USDA released the new standards in January. Most observers viewed them as an important accomplishment of the first lady’s Let’s Move campaign to end childhood obesity within a generation.

What about student outrage that the new meals leave them hungry? As a strong supporter of student activism, I applaud students getting involved in protests. Their actions have already persuaded Agriculture Secretary Tom Vilsack to tell kids to eat healthy snacks if they are hungry.

Perhaps student activism around calories will be a first step toward advocacy for more substantive goals for their education and wellness: more and better paid teachers, better educational materials, more sensible testing, better quality food in schools, and instruction in how to grow, harvest and cook food.

But where, I wonder, are the adults in all of this? Childhood obesity is not trivial in its consequences for many kids, and school food ought to be a model for how healthy, delicious food is normal fare.

Schools in which adults – principals, teachers, school food personnel and parents – care about what kids eat and act accordingly are setting examples that what kids eat matters just as much as what kids learn.

It’s shameful that elected officials would attempt to undermine the health of America’s children for partisan political purposes.
