Food safety roundup

I’ve been collecting items on food safety for the last week or two. Here’s a roundup for a quiet Friday in July:

Antibiotics in animal agriculture

     USA Today does great editorial point/counterpoints and here is one from July 12 on use of antibiotics as growth promoters or as  prophylactics in farm animals and poultry.  This selects for antibiotic-resistant bacteria.   If we get infected with antibiotic-resistant bacteria, too bad for us. 

     The paper’s editors think that use of antibiotics for these purposes is irresponsible:  Our view on food safety: To protect humans, curb antibiotic use in animals.

     Dr. Howard Hill, a veterinarian who directs the National Pork Producers Council, defends these uses of antibiotics: Don’t bar animal antibiotics.

The source of the 2006 E. coli 0157:H7 outbreak in California spinach

     USDA and UC Davis investigators are still trying to figure out how the toxic E. coli O157:H7 got onto the spinach. Investigators did not find the bacteria on the spinach field itself, but they did find it in water, cattle, and cattle feces at a cattle crossing over a stream one mile away. Leading hypotheses: runoff from that stream or wild boar.

     Subsequent studies showed low levels of E. coli 0157:H7 in wild animals and birds.  A new study confirms that just under 4% of wild boar harbor the bacteria. 

     The investigators say the spinach outbreak of 2006 was the result of a combination of circumstances: “Everybody is starting to realize that maybe unusually heavy rainfall prior to planting could be an issue in terms of where water is routed.”

     Dairy farming is moving into California’s Central Valley in a big way.  Runoff from those farms will not be sterile and growing vegetables along water routes may be risky.  Compost, anyone?

The chemical behind Kellogg’s cereal recall

     Kellogg recalled 28 million packets of breakfast cereals last month because people reported funny smells and getting sick from something in the packaging.  At first, Kellogg would not say what the chemical contaminant might be.  

     Then it said the chemical is methylnaphthalene. Mothballs! (Are they still making mothballs?  Their smell is unforgettable)

     Tom Philpott’s comments on Grist.com point out what’s really at stake: “And of course, the real scandal is what Kellogg’s is marketing to kids: a tarted-up slurry consisting mainly of sugar, corn products, partially hydrogenated oil, and food colorings. But that’s a whole different story.”

Salsa and guacamole are sources of foodborne illness

     The CDC reports that salsa and guacamole are becoming more frequent sources of contaminants leading to illness.  CDC started collecting information on sources of outbreaks in 1973.  Its first outbreak due to salsa or guacamole occurred in 1984.  Since then, there have been 136 such outbreaks.  Restaurants and delis were responsible for 84%.  Between 1984 and 1997, salsa and guacamole outbreaks accounted for 1.5% of total foodborne outbreaks.  But the percentage rose to 3.9% from 1998 to 2008.

     Moral: make your own!

China deals with melamine in milk powder

     China is taking creative steps to prevent melamine from getting into milk powder and infant formula.  To discourage fraudulent producers from boosting up the apparent level of protein in milk with melamine, it simply reduced the amount of protein required.

The latest on food irradiation

     FoodSafetyNews.com presented a two-part series on food irradiation (part 1 and part 2), both of them quite favorable to the technology. As I discuss in my book, Safe Food, I don’t have any safety ojections to food irradiation, but I consider it a late-stage techno-fix for a problem that should never have occurred in the first place.

     I conclude with my favorite quote from former USDA official Carol Tucker Foreman: “sterilized poop is still poop.”

Enjoy a safe weekend!

Two GAO reports on FDA’s food safety problems

Food Safety: FDA Has Begun to Take Action to Address Weaknesses in Food Safety Research, but Gaps Remain. GAO-10-182R, April 23, 2010 (23 pages).

Imported food makes up a substantial and growing portion of the U.S. food supply, with 60 percent of fresh fruits and vegetables and 80 percent of seafood coming from across our borders….In January 2007 GAO designated federal oversight of food safety as a high-risk area needing urgent attention and transformation because of the federal government’s fragmented oversight of food safety. The Food and Drug Administration (FDA) is responsible for ensuring the safety of roughly 80 percent of the U.S. food supply–virtually all domestic and imported foods except for meat, poultry, and processed egg products–valued at a total of $466 billion annually, as of June 2008.

Food Safety: FDA Could Strengthen Oversight of Imported Food by Improving Enforcement and Seeking Additional Authorities.  GAO-10-699T, May 6, 2010 (20 pages).

In 2008, FDA inspected 153 foreign food facilities out of an estimated 189,000 such facilities registered with FDA…. FDA estimated that it would conduct 200 inspections in 2009 and 600 in 2010. GAO previously identified several gaps in enforcement that could allow food products that violate safety laws to enter U.S. commerce. For example, FDA has limited authority to assess penalties on importers who introduce such food products, and the lack of a unique identifier for firms exporting food products may allow contaminated food to evade FDA’s review.

As it has been saying for years, GAO wants FDA to ask Congress to give it statutory authority to:

  • Recall products identified as unsafe
  • Require companies to demonstrate that food ingredients are safe before using them
  • Require preventive controls (e.g. HACCP) by firms producing foods that have been associated with repeated instances of serious health problems or death.

Note that the FDA does not have this authority now and must seek it from Congress.  The food safety bill now before Congress does some of this, which is one reason why it should be passed.  Note: the House passed the bill last August.  Eleven months later, the Senate is still sitting on it.  Not helpful.

Addition: Consumers Union has produced a video—starring Eric Schlosser—on why the Senate must pass the food safety bill, and right away.

Update, July 8: President Obama states support of the Senate’s food safety bill.

A how-to guide for companies involved in food recalls

Bill Marler, the Seattle attorney whose firm represents victims of foodborne illness, has seen the best and worst of company behavior when faced with pressures to “voluntarily” recall tainted products.  Here is his guide to good corporate behavior under difficult circumstances.  It begins with “don’t produce tainted products in the first place.”   But, alas, if you do:

First, have a pre-existing relationship with the folks that regulate you. If someone holds your business in the palm of his or her hand, you should at least be on a first name basis. No, I am not suggesting that you can influence your way out of the outbreak, but knowing who is telling you that your company has a problem allows you the ability to get and understand the facts. Do regulators and their investigators make mistakes? Perhaps, but not very often and not often enough to waste time arguing that your company did not poison customers.

Second, stop production of the implicated product and initiate a recall of all products at risk immediately. This procedure should have been practiced, and practiced, and practiced before. All possibly implicated suppliers should be alerted and all retailers should be offered assistance. Consumers need to be engaged too. The goal now is to get poisoned product out of the marketplace and certainly out of the homes of consumers.

Third, launch your own investigation with two approaches, and at the same time. Are the regulators correct? And, what went wrong? Tell everyone to save all documents (you have to anyway). The goal here is to get things right. If it really is not your product, what has happened is bad, but survivable. If it really was your product, then learning what happened helps make sure it is likely to never happen again. More than anything, be transparent. Tell everyone what you find–good or bad.

Fourth, assuming that the outbreak is in fact your fault, publicly admit it. If it is not your fault, then fight it. However, pretending that you are innocent when you are actually at fault will get you nowhere. Asking for forgiveness is not a bad thing when you have something to be forgiven for. Saying you are sorry is not wrong when you are in fact wrong.

Fifth, do not blame your customers. If your food has a pathogen it is not your customers’ responsibility to handle it like it will likely kill them or a member of their family. Hoping that the consumer will fix your mistake takes your eye off of avoiding the mistake in the first place.

Sixth, reach out to your customers and consumers who have been harmed. Offering to pay legitimate losses will save money and your company’s reputation in the long run.

Seventh, teach all what you have learned. Do not hide what you have learned. Make your knowledge freely available so we all limit the risk that something similar will happen again.

In other words, do the right thing.  Excellent advice.

But Mr. Marler cites no examples.  I wonder if there are companies that actually did all this?  It would be good to know who they are.

Thinking about food safety

Food safety is in the news again.

Congressman John Dingell (D-Mich) is calling on the Senate to get busy and pass the food safety bill that it has been sitting on for the last ten months: “I urge my Senate colleagues to acknowledge this important threat and make legislation addressing it a priority. Until the Senate acts, American families will continue to be at risk.”

If this bill ever passes it will require food companies to develop food safety plans, authorize the FDA to order recalls, and give the FDA better access to company records.

But will it do any good?

Here is one view from Dennis Stearns, counsel in the Seattle law firm, Marler & Clark, which represents victims of foodborne illnesses.  In a piece in Food Safety News, “What the oil spill can teach us about food safety,” he notes the endlessly repetitive responses–all talk, no action–to food safety and other crises involving corporate irresponsibility.

He quotes USDA Secretary Vilsack saying, “You can’t have two [food safety] systems and be able to reassure people you’ve got the job covered…This [referring to the peanut recalls of last year] is a grand opportunity for us to take a step back and rethink our approach.'”

Stearns’ piece concludes with this comment on Vilsack’s remarks:

Sadly, this was not the first time that someone had pointed out the need for systemic revision to food safety regulation and inspection in the United States. And neither was it the first time that expressions of outrage over people dying from foodborne illness were followed by no real changes at all. And all I can say about that is: I’m shocked! No, really, I’m shocked!

In contrast, Jim Prevor,who writes as the Perishable Pundit, writes in the online New Atlantis: A Journal of Science and Technology that fixing the FDA will do little to address food safety problems.  Instead, he recommends:

  • Fix the liability system so retailers as well as producers are liable and make it legal negligence, not strict liability.
  • Root out bribery and corruption in food safety certification.
  • Invest in state testing laboratories.
  • Invest in food safety research.
  • Revitalize the Agricultural Extension Service.
  • Educate consumers.

I’m not sure about the legal liability issues, but most of the rest are really good ideas and would help a lot.  Of course consumers should follow food safety procedures but how about getting safe food to them in the first place?

None of this will happen without policy changes, which is why the food safety legislation matters so much.  It’s a national scandal that the Senate is still sitting on that bill.

USDA’s latest collection of relevant reports

The USDA does terrific research on many useful topics.  Here is a sample of some just in.

STATE FACT SHEETS:  data on population, per-capita income, earnings per job, poverty rates, employment, unemployment, farm characteristics, farm financial characteristics, top agricultural and export commodities.

WIC PROGRAM: research, publications, and data related to WIC (Special Supplemental Nutrition Program for Women, Infants, and Children). WIC served 9.1 million participants per month at a cost of $6.5 billion in 2009.

FEED GRAINS DATABASE: statistics on domestic corn, grain sorghum, barley, and oats; foreign grains plus rye, millet, and mixed grains. You can also get historical information through custom queries.

LIVESTOCK, DAIRY, AND POULTRY OUTLOOK:  current and forecast production, price, and trade statistics.

AGRICULTURAL OUTLOOK STATISTICAL INDICATORS: commodity and food prices, general economic indicators, government program expenditures, farm income estimates, and trade and export statistics.

ASPARAGUS STATISTICS: acreage, yield, production, price, crop value, and per capita use; also world area, production, and trade.

FOODBORNE ILLNESS COST CALCULATOR:   the cost of illness from specific foodborne pathogens, depending on the  annual number of cases, distribution of cases by severity,  use or costs of medical care, amount or value of time lost from work,  costs of premature death, and disutility costs for nonfatal cases.

ORGANIC FARMERS: explains why use of organic practices in U.S. lags behind other countries, differences and similarities between organic and conventional farmers, reduced consumer demand resulting from the weaker U.S. economy,  and potential competition from the “locally grown” label.

LOCAL FOOD SYSTEMS: defines local food,  market size and reach,  characteristics of local consumers and producers, and  economic and health impacts.  Addresses whether localization reduces energy use or greenhouse gas emissions (inconclusive).

BIOFUELS: Reaches 88 million gallons in 2010 as a result of one plant becoming commercially operational in 2010, using fat to produce diesel. Challenges include reducing high costs and overcoming the constraints of ethanol’s current 10-percent blending limit with gasoline.

Thanks to USDA for producing data that policy wonks like me just love to cite.

The source of E. coli 0145?

Bill Marler, the Seattle attorney who represents victims of food poisonings, consistently urges federal food safety agencies to reveal what they know so consumers can protect themselves from unsafe food.

He is especially annoyed that the FDA has not revealed the name of the farm in Yuma, Arizona, linked to the bagged romaine lettuce that has sickened more than 30 people in several states so far with the unusual form of E. coli, 0145.

Marler knows how to get information (although not always accurate results, apparently – see update below).  He first offered $5,000–and later offered $10,000–as a reward to anyone who revealed the name of the farm before the FDA did (the money goes to charity).  He got two takers. Both identified a particular firm in California as the source.

Update, May 22:  I received a message today from Leslie Krasny, partner in the law firm of  Keller and Heckman, LLP, San Francisco, which represents the farm named by those sources.  She advises me that there is no evidence linking her client’s romaine lettuce to the outbreak and that her client is not even under investigation by the FDA.  She asks that I delete reference to her client, which I have done.  Mr. Marler also has done so.

Food (un)safety update: E. coli 0145 in Arizona lettuce and more

It’s deja vu all over again with the recent recall of bagged romaine lettuce contaminated with a toxic form of E. coli.  The lettuce came from a central wash-and-bag facility that sent products out to food service companies in several states making about 30 people sick so far.

The one new development is the strain of E. coli: 0145, not O157:H7.  Despite decades of worry that other STECs (Shiga Toxin-producing strains of E. coli) cause serious human illness, state health departments don’t routinely test for 0145.  Clearly, they need to.

The FDA and CDC are both working on this case.

FoodSafetyNews.com has a complete report on the situation to date.  It examines the possible source of 0145 in a three-part series:

Meanwhile, the USDA issued compliance guidelines for reducing Salmonella and Campylobacter in poultry.  That’s nice, but what about STECs?

And the GAO has just issued a new report, FDA Could Strengthen Oversight of Imported Food by Improving Enforcement and Seeking Additional Authorities (don’t you love those titles?).  The report focuses on weaknesses in FDA’s oversight of food imports.

FoodQualityNews.com has a short but tough summary:

There are about 189,000 registered foreign sites where food is made for sale in the United States, according to the report. Of those, the FDA inspected just 153 in 2008…Meanwhile, the amount of food imported into the United States is increasing, and now accounts for 15 percent of the total food supply, including 60 percent of fresh fruits and vegetables and 80 percent of seafood.

What more evidence do we need for the urgency of passing food safety legislation?  Reminder: the Senate has been sitting on a food safety bill since the House passed it last August.  Apparently, this Congress this food safety can wait.  Tell that to the people who got sick from eating bagged romaine lettuce.

Food safety progress: some good news, some not

On April 16, the CDC published its annual report on foodborne illnesses in a ten-state sample.  CDC writes in passive voice and it’s a struggle to get to the good news:

In comparison with the first 3 years of surveillance (1996–1998), sustained declines in the reported incidence of infections caused by Campylobacter, Listeria, Salmonella, Shiga toxin-producing Escherichia coli (STEC) O157, Shigella, and Yersinia were observed…Compared with the preceding 3 years (2006–2008), significant decreases in the reported incidence of Shigella and STEC O157 infections were observed.

Some consumer groups urge caution in interpreting the drop in toxic E. coli cases, as previous drops have rebounded.

And then there’s the not-so-good news: “The incidence of Vibrio infection continued to increase.”

Vibrio infections reflect the oyster problem I talked about last fall.  The gulf oyster industry is still fighting the FDA over methods to decrease these preventable infections.  Perhaps this bad news will encourage the FDA to get busy and regulate oyster safety.

The Inspector General of the Department of Health and Human Services is worried about FDA’s inspection ability:

  • On average, FDA inspects less than a quarter of food facilities each year, and the number of facilities inspected has declined over time.
  • Fifty-six percent of food facilities have gone 5 or more years without an FDA inspection.
  • The number of facilities that received OAI [Official Action Indicated] classifications has declined over time.  In addition, nearly three-quarters of the facilities that received OAI classifications in FY 2008 had a history of violations. Two percent of facilities that received OAI classifications refused to grant FDA officials access to their records.
  • FDA took regulatory action against 46 percent of the facilities with initial OAI classifications; for the remainder, FDA either lowered the classification or took no regulatory action.
  • For 36 percent of the facilities with OAI classifications in FY 2007, FDA took no additional steps to ensure that the violations were corrected.

This is also bad news.  Worse, is congressional inaction over food safety.  The House passed its food safety bill–one designed to fix the FDA–last August.  The Senate has yet to deal with its version.  Can food safety wait?  No, it must not.
