Is Stevia really “natural?”

The April 26 New York Times Magazine carried a seductive ad on page 15 for PepsiCo’s “Trop50 orange juice goodness with 50% less calories and sugar…And no artificial sweeteners”  PepsiCo performs this miracle by diluting the juice by half with water (really, you could do this at home).  But in case the result isn’t sweet enough for you, Trop50 adds the sweetener, Stevia.

PepsiCo can get away with claiming that its juice drink has no artificial sweeteners.  Because Stevia is isolated from leaves of the Stevia plant, the FDA lets companies claim it is “natural.”

We can debate whether a chemical sweetener isolated from Stevia leaves is really “natural” but here’s another problem: Stevia doesn’t taste like sugar.  Companies have to fuss with it to cover up its off taste.  And, they must do so “without detracting from the perceived benefits of its natural status.”  Flavor companies are working like mad to find substances that block Stevia’s bitter taste, mask its off flavors, and extend its sweetness, while staying within the scope of what the FDA allows as “natural.”

Yesterday, I received an e-mail from a Stevia PR representative eager for me to see the company’s website.  “Naturally delicious” anyone?

Pesticides in Chilean farmed salmon?

Among the many publications that flood my snail mailbox is the trade magazine, Pacific Fishing. I’m not sure why it gets sent to me but I do look at it since it covers a world I know little about.   The May issue has several articles about banned pesticides in Chilean farmed salmon.  I had completely missed this story, even though the New York Times discussed the problem on February 5.  That was the day the Pew Environmental Group revealed the results of its FOIA (Freedom of Information Act) request to the FDA.  The otherwise undisclosed documents say farmed fish from Chile contains residues of pesticides banned by the FDA since 2007.

But Chile is not alone in using banned pesticides.  British Columbia salmon farmers use SLICE, a pesticide that kills sea lice.  Because such pesticides are toxic, it is not surprising that they also seem to be killing local prawns and other invertebrates along the Canadian West Coast.

A Pacific Fishing reporter, Don McManman, went to great pains to find out what the FDA was doing about all this.  His interview makes entertaining reading.  The FDA’s final answer?  Looking into it, apparently.

I’m wondering why the Pew Group had to file a FOIA request to get information that the FDA should be releasing to the public.  The lack of disclosure makes it appear that the FDA cares more about protecting the salmon farming industry than consumers, especially now that the public has the right to choose.  Seafood has Country-of-Origin labeling (COOL).  With COOL , you can see whether farmed salmon comes from Chile or British Columbia and decide for yourself whether you want to eat fish raised on pellets containing banned pesticides.

Want to check out the documents?  Go to the Pacific Fishing website, then Resources. Scroll down and look for “Insecticides–It’s What’s for Dinner,” “Chile Salmon Report,” and “Chilean Contamination History.”

Do endocrine disrupters cause asthma and obesity?

According to press reports, investigators from a Mt. Sinai School of Medicine project funded by the Environmental Protection Agency (EPA), “Growing Up Healthy in East Harlem,” find higher levels of endocrine disrupters, mostly phthlates and bisphenol A, among obese girls (age six to eight) in East Harlem, as compared to girls who are not obese.   The actual research does not appear to be published yet – I can’t find it on the Epidemiology website – but the EPA’s site provides the latest report on the project.

Endocrine disrupters are widely used in food and beverage packaging materials, as well as things such as cosmetics, shampoos, lubricants, and paint. As I explained in earlier posts, federal agencies have been taking a hard look at such substances, particularly bisphenol A.  Their interim conclusion: such chemicals pose no harm at current levels of intake.

While waiting for more research or regulatory action, a group called As You Sow has asked food companies what they are doing about bisphenol A.  Its report, Seeking Safer Packaging, concludes that the companies it surveyed generally aren’t doing nearly enough.  A few companies – notably Hain Celestial, Heinz, and Nestle (no relation) do have plans to phase out these chemicals eventually.

Why isn’t there more research on endocrine disrupter chemicals?  Without it, we have only two choices: precaution or do nothing and see what happens.  In this instance, it looks like the evidence favors precaution.  Glass bottles, everybody!

One food safety system: a vision

The New York Times, in an editorial “Food safety, one pistachio at a time,” says “it is time to think seriously about establishing one federal agency to coordinate and enforce food-safety regulations.”  And Michael Taylor and Stephanie David of the George Washington University Department of Health Policy provide a major position paper arguing that food safety must be a joint effort among federal, state, and local health agencies to address risks across “the farm-to-table spectrum of food production, processing, distribution, retailing, and home preparation.”  Let’s hope Congress is listening as it ponders the various bills introduced to fix the FDA or fix the entire food safety system.

Busy weekend: the Obama’s First Puppy and Fixing the FDA

In case you were wondering about my thoughts on what the Obamas should be feeding their new First Puppy, I did an interview with Obama Foodorama on that very topic: “The Obamas get a new puppy and policy issues get unleashed.”

And for my latest column in the San Francisco Chronicle, “Full plate for Obama’s new FDA administrator,” I deal with the question of what the new FDA Commissioner, Dr. Margaret Hamburg, needs to do to fix the agency’s problems. She will need all the support we can give her.

Pistachio recalls: curioser and curioser

The FDA, reports the New York Times, is getting tougher about food safety, and about time too.  Within the last few days, the FDA has issued guidance to industry about how to deal with pistachios, warned food companies that they must follow Good Manufacturing Practices, explained to companies how recalls are supposed to be done, warned consumers not to eat pistachios unless their source is known, and continued to  update the list of recalled products.

None of this gets at the real problems: the lack of a unified food safety system with some teeth in it, resources to carry out food safety oversight and inspections, and authority to order recalls of potentially unsafe food (recalls, as I keep reminding you, are voluntary).  And I guess we should add traceability.  According to the account in USA Today, the plant that shipped the contaminated pistachios has no idea where they all went.

Pistachio growers have stepped into the breach and now have a website listing products that have not been recalled.

The FDA’s handling of the pistachio situation differs sharply from the agency’s usual way of handling such things.  Usually, the FDA waits for people to get sick before taking action.  The odd thing here is that nobody seems to have gotten sick from eating contaminated pistachios.  So what the FDA is doing is working – so far.

And all this is happening under the leadership of an Acting Commissioner while the newly appointed Commissioner, Dr. Margaret Hamburg, awaits congressional approval.

May 26 update: FoodProductionDaily.com reports that the supplier of Salmonella-contaminated pistachios had tested the nuts, found them to contain Salmonella, and re-heated them, but didn’t bother to check to make sure the Salmonella were killed or that the nuts weren’t recontaminated with unroasted nuts.  Bill Marler has more to say about this.  Here’s the FDA inspection report of April 30, and the FDA Pistachio recall page again.

Can food products be traced? Not easily.

In 2005, the FDA required certain categories of manufacturers to keep records about the source, transporters, and recipients of their products.  Recently, the Inspector General of the FDA’s parent agency, the Department of Health and Human Services, conducted an exercise to see whether traceability was working.  Inspectors bought 4 samples of 10 different food products (e.g., bottled water, oatmeal, tomatoes) at retail stores and attempted to track their supply chains.  Oops.  It only could trace 5.  For another 31, it could make educated guesses.  But nearly 60% of food facilities handling these products could not complete the tracing and 25% did not know they were supposed to.

The FDA, says the Inspector General, needs statutory authority to require producers to know their supply chains and everybody involved needs some education about how to do this.  No wonder we are still getting daily recalls of products containing peanut better.  Statutory authority means Congress.  I wish Congress would get busy on this!

And now you can’t eat pistachios either

The FDA is announcing the “voluntary” recall of certain pistachio products.  Certain, in this case, means a mere million pounds of products from Setton Pistachios of Terra Bella, CA.  These appear to be contaminated with multiple strains of Salmonella. As with the peanut butter recalls, pistachios are used in many different kinds of products.  The FDA learned about the problem from Kraft Foods, which found Salmonella in its Back to Nature Trail Mix. Nobody has gotten sick yet, but stay tuned.  The FDA has a brand new pistachio recall page on its website.  Now you can keep track of pistachio recalls along with the peanut butter recalls which continue to come in every day and now add up to nearly 4,000 products.

Will this ever end?  While waiting for Congress to approve the appointment of Dr. Margaret Hamburg as FDA Commissioner, her deputy, Joseph Scharstein, has just taken over as acting commissioner.  These new officials will have plenty of work to do to get this mess under control.
