Today’s food politics of Ebola

Ebola is much in the news, and for good reason.  It is highly contagious, difficult to contain, and deadly.

In food studies, we say that food is a lens through which to view the most important problems of society.  Here are some thoughts on the food politics of Ebola.

Dietary Supplements for Ebola Prevention or Treatment

The Council for Responsible Nutrition, the trade association for supplement manufacturers, has found it necessary to issue an advisory on use of dietary supplements to prevent or treat Ebola infections.

The American Herbal Products Association (AHPA), the Consumer Healthcare Products Association (CHPA), the Council for Responsible Nutrition (CRN), the Natural Products Association (NPA), and the United Natural Products Alliance (UNPA) are therefore endorsing the following unified advisory for marketers and retailers, as well as for consumers of dietary supplements:

  • Marketers and retailers of dietary supplements are urged to refuse to stock or sell any supplements that are presented as treating or curing Ebola virus disease, or preventing Ebola virus infection.
  • Marketers and retailers should refrain from promoting any dietary supplement as a cure or treatment for Ebola virus disease.
  • Anyone who believes they may have Ebola virus disease or may have come in contact with the Ebola virus should contact a healthcare professional immediately. The Centers for Disease Control and Prevention has more information on Ebola virus disease and the proper actions to take if you suspect you are ill.

The knowledge that no known treatment exists for Ebola has not stopped supplement manufacturers from advertising the benefits of their products for this infection.

FDA Warning Letters

The FDA has stepped in and issued warning letters to three manufacturers marketing their products as possible treatments or cures.  The FDA letters, which make interesting reading, went to:

Marketing of Nutritional Supplements

A simple Google search of “supplements Ebola” turned up this kind of information this morning:

The Ebola virus can be destroyed naturally – despite what you’ve been told To date, not a single virus has been tested that is not inactivated (killed) by a large enough dose of vitamin C (ascorbic acid). Many other antioxidants have similar virucidal effects, but vitamin C appears uniquely to be of greatest potency and clinical efficacy, as its simple chemical structure allows for it to be disseminated throughout the body with little restriction… Vitamin C is both very potent and optimally bioavailable in accessing any viral infection.

And this:

The substances in the Natural Allopathic protocol for Ebola offer a power unequalled in the world of medicine that we can harness to save many lives of people infected with Ebola…. Magnesium salts, sodium bicarbonate (baking soda), iodine, selenium and vitamin C are concentrated nutritional medicinals that have been used in the direst of medical circumstances…The core of the Natural Allopathic protocol redefines the way emergency room and intensive care should be practiced on Ebola patients with proven fast-acting, safe, concentrated and mostly injectable nutritional medicines. If the Ebola infection truly gets out of hand, it is comforting for parents to know that they can legally administer these same medicinals if infected people are treated at home. All of the Natural Allopathic Medicines can be also taken orally or used transdermally (topically) to almost the same effect if treatment is started early enough.

How Can Supplement Makers Do This?

The ability of supplement manufacturers to claim health benefits for their products, and mostly get away with it, is a result of congressional action in passing the Dietary Supplement Health and Education Act of 1994 (DSHEA), which essentially deregulated these products.

Twenty years later, the supplement industry is deeply divided between responsible and irresponsible manufacturers, both allowed by law.

As the president and CEO of one supplement company puts it,

The industry of 1994, roughly $8 billion in sales, has experienced compounded double-digit growth every year since DSHEA became law…DSHEA opened the door to growth, innovation, new science, new discovery and a nation of wanting consumers enchanted with the thought that there are natural solutions to their individual health needs…20 years later, it’s time to take a hard look at what DSHEA doesn’t provide to the industry today. The barrier to entry into this industry continues to have no hurdles; DSHEA does not define the boundaries of consumer trust… The generations of today, and the generations of tomorrow will demand transparency, they will demand efficacy, and they will demand quality and safety from all of us.

Clearly, they aren’t getting that now.

Other Connections to Food Politics

Chocolate

Politico writes:

EBOLA THREATENS WORLD’S CHOCOLATE SUPPLY:  Ivory Coast, the world’s largest producer of cacao, the raw ingredient in M&Ms, Butterfingers and Snickers Bars, has shut down its borders with Liberia and Guinea, putting a major crimp on the workforce needed to pick the beans that end up in chocolate bars and other treats just as the harvest season begins… the outbreak already could raise prices…Prices on cocoa futures jumped from their normal trading range of $2,000 to $2,700 per ton, to as high as $3,400 in September over concerns about the spread of Ebola to Côte D’Ivoire.

Food safety

Food safety lawyer Bill Marler points out that Ebola started out as a foodborne illness.    Its most likely source was infected bushmeat that transferred the virus to human handlers.

Following standard food safety procedures is always a good idea while hoping that health officials get this epidemic under control.

Oops. USDA is NOT requiring poultry packers to test for Salmonella and Campylobacter

Christopher Waldrop, who directs the Food Policy Institute at Consumer Federation of America writes to correct something  I said in a post last week about USDA’s poultry rule.  He says:

USDA will actually NOT be requiring plants to test for Salmonella or Campylobacter. Their press release makes it sound like they will, but if you read the final rule, USDA actually allows the plant to decide for itself what to test. It could be pathogens like Salmonella or Campy, OR it could be indicator organisms like generic E. coli. USDA does require testing at 2 points along the line – pre-chill and post-chill and will require a minimum testing frequency, but plants are not obligated to test for the pathogens that make people sick.

He explained this problem to Food Safety News and in a press release.

He points out that what the USDA really said is on page 229 of its statement of policy in the section on Indicator Organisms and Baseline:

Comment: Several consumer advocacy organizations argued that instead of allowing establishments to choose which organism to test for, FSIS should require that establishments test for Salmonella and Campylobacter. The comments said that these are the two pathogens of greatest public health concern in the products affected by the proposed rule and together account for nearly half of all poultry-related outbreaks in the United States…Response: As discussed above, the purpose of the proposed new testing requirements is to ensure that establishments are effectively monitoring process control on an ongoing basis. FSIS has determined that this can be achieved by sampling pre-and post-chill for enteric pathogens, such as Salmonella and Campylobacter, or for an appropriate indicator organism…The cost to analyze samples for Salmonella and Campylobacter is much greater than that to analyze for indicator organisms…FSIS has concluded that such costs would not be justifiable when measurements of indicator organisms are as effective for monitoring process control as measurements of pathogens.

Here’s what USDA says in its press release:

  • Poultry companies will have to meet new requirements to control Salmonella and Campylobacter.
  • FSIS will now require that all poultry companies take measures to prevent Salmonella and Campylobacter contamination.
  • All poultry facilities will be required to perform their own microbiological testing at two points in their production process to show that they are controlling Salmonella and Campylobacter.

I can see why I misunderstood this as announcing a requirement for testing at two points for Salmonella and Campylobacter.

But the USDA is leaving it to the production plants to demonstrate that cheaper testing for an indicator organism like nonpathogenic forms of E. coli will adequately demonstrate that chickens are free of pathogenic Salmonella and Campylobacter.

Fingers crossed that it works.

Addition, September 11:  Food and Water Watch has filed suit against the USDA to block the new poultry inspection system on the grounds that it privatizes inspection responsibility, at great hazard to the public.

USDA’s new poultry inspection system, complicated but voluntary

I thought it might be time for a summary of why USDA’s new requirements for poultry inspection are so controversial.  Some groups think they are a big step forward; others most definitely do not.

The USDA says its new rules, which are largely based on research published in 2011:

  • Will place new requirements on the poultry industry.
  • Will prevent 5000 illnesses a year from Salmonella and Campylobacter
  • Puts trained USDA inspectors where they will do the most good.
  • Require poultry facilities to test for Salmonella and Campylobacter at two points during production (USDA will continue to do its own testing).
  • Giving poultry producers the option of doing their own inspections.
  • Caps the maximum line speed at 140 birds per minute (rather than the 175 the industry wanted).
  • Estimates the public health benefit at $79 million.

It also says

More inspectors will now be available to more frequently remove birds from the evisceration line for close food safety examinations, take samples for testing, check plant sanitation, verify compliance with food safety plans, observe live birds for signs of disease or mistreatment, and ensuring plants are meeting all applicable regulations.

To read the Federal Register notice (when it’s ready), click here.

The main issues

Line speed:  this refers to the evisceration line and is the speed at which workers must deal with the chickens.  The current speed is 140 birds per minute.  This means 2.33 birds per second.   It’s hard to imagine that any worker could manage that—or any inspector could see anything—at that speed.

The National Council of La Raza wrote USDA  in 2012 that raising the line speed posed a hazard to worker safety and “would recklessly threaten the health and safety of poultry workers.”  USDA listened.  The NCLR must be pleased.

The poultry industry is not pleased.  The National Chicken Council complains that “politics have trumped sound science, 15 years of food and worker safety data and a successful pilot program with plants operating at 175 birds per minute.”

Politico ProAg points out that the new system will cost the poultry industry $259 million—what it would have gained if line speeds increased to 175 per minute.

Privatization of inspectors.  The new rules shift responsibility for inspecting chickens, no matter how impossible, to company employees—the fox guarding the chickens, as it were. Food and Water Watch argues that this poses a conflict of interest since it’s in the managers’ interest to keep the lines moving as fast as possible and not to find anything wrong.   Food and Water Watch says the new system “will transfer most poultry inspection from government inspectors to the companies so they can police themselves.” Several members of Congress have also complained.   The Government Accountability Office (GAO) issued a report noting that USDA doesn’t really have data on which to base this change.

Change in function of USDA inspectors.  Up to 1,500 USDA phased out of poultry production may have to relocate or retire.  USDA estimates it will save $90 million over the next three years from this reduction.

Turkeys.  The new system allows turkey plants to raise line speeds to 55 per minute, up from 51 birds per minute.  The National Turkey Federation says most turkey plants will comply.

Waivers.  The Washington Post says the new system “provides a waiver to 20 plants that are already in a pilot program, letting them operate at 175 birds per minute.”

Voluntary.  The program is voluntary.  Plants can continue doing things the way they are.  

What to make of all this?  The testing requirements are a huge step forward.  The inspection changes seem mixed. It’s hard to believe that line inspection is useful even at 140 birds per minute.  

I’d rather have USDA inspectors making sure prevention controls are in place and adhered to, the testing is done honestly, and keeping an eye out for unsafe worker conditions (which, alas, is not their job).  

Let’s give it a try and see how it works in practice.

In the meantime, here’s what else is happening on the poultry safety front:

Other related news

Salmonella is not an adulterant, says USDA.  If it were, anything contaminated with it could not be sold.  USDA denied the petition from Center for Science in the Public Interest to have four antibiotic-resistant strains of salmonella declared as as adulterants in ground meat and poultry products.

After thoroughly reviewing the available data, FSIS has concluded that the data does not support giving the four strains of [antibiotic-resistant] salmonella identified in the petition a different status as an adulterant in raw ground meat and raw ground poultry than salmonella strains susceptible to antibiotics.

The Foster Farms Salmonella outbreak is over, says the CDC.

The CDC announced today a total of 634 persons infected with seven outbreak strains of Salmonella Heidelberg were reported from 29 states and Puerto Rico from March 1, 2013 to July 11, 2014.

Epidemiologic, laboratory, and traceback investigations conducted by local, state, and federal officials indicated that consumption of Foster Farms brand chicken was the source of this outbreak of Salmonella Heidelberg infections.

38% of ill persons were hospitalized, but no deaths were reported.

Most ill persons (77%) were reported from California, but cases were reported in other states as well.

And that’s why all of this matters so much.

Annals of food law: Peanut Corporation of America

OK, everyone is presumed innocent until proven guilty, and executives of the Peanut Corporation of America (PCA) are getting their day in court, accompanied by an aggressive legal defense.

According to Food Safety News, PCA’s lawyers are claiming that the government’s requests for disclosure documents are so egregious that the case should be dismissed.

Here’s a comment on the case from Eat, Drink, Vote: An Illustrated Guide to Food Politics:

001

Irony alert: “egregious” is precisely the word I used to describe PCA’s actions related to its Salmonella problems more than a year ago:

I’ve been following this particular food safety tragedy for several years now.  The offenses were so egregious—officials blatantly ignored positive tests for Salmonella, for example—that some kind of punishment seemed warranted.

According to the account in USA Today:

The indictment alleges that PCA officials affirmatively lied to their customers about the presence of salmonella in PCA’s products,” said Stuart Delery, principal deputy assistant attorney general.

Delery also said some officials at PCA, no longer in business, fabricated lab results certifying to customers that the products were salmonella free “even when tests showed the presence of salmonella or when no tests had been done at all.”

If you would like to catch up on this endlessly fascinating case, in which contaminated peanut butter made 714 people in 46 states sick, here’s Food Safety News’ year-old timeline of its events.

CDC’s food safety report card: no happy news

The CDC has just issued its latest report on foodborne illness and food safety progress from 2006 to 2013.

It’s report has a couple of frowny faces—Campylobacter and Vibrio cases are up—and nothing else has changed.

Nothing to smile about.

Laboratory diagnoses of other foodborne microbial illnesses are also rising.

Figure: Changes in incidence of laboratory-confirmed bacterial infections, United States, 2013 compared with 2006-2008 (data are preliminary). Yersinia = 7% decrease, Vibrio = 32% increase, STEC Non-O157  = 8% increase, STEC O157 = 16% increase, Shigella = 14% decrease, Salmonella = 9% decrease, Listeria = 3% decrease, Campylobacter = 2% increase

The food industry needs to do a better job of producing safe food.

Let’s hope the new food safety rules go into effect soon and get followed.

Salmonella is NOT an inherent part of chicken, proves Denmark

Yesterday, Food Safety News republished the last of a four-part series in the Portland Oregonian about how Denmark was able to get rid of Salmonella in chickens, but we can’t. 

This one explains why.

[USDA] announced a plan last year to stem Salmonella. Its goal is to reduce illnesses by 25 percent by 2020. The plan, which is still being rolled out, includes a controversial overhaul of inspections, enhanced testing and a first-ever limit on allowed Salmonella in cut-up chicken.

Denmark opted for a more comprehensive approach, attacking Salmonella in flocks, poultry barns, animal feed and slaughterhouses.

Why can’t we do that too?

  • The U.S. chicken industry is too big.
  • Reforms would cost too much.
  • Chicken prices would rise.
  • Chicken would cost more than beef.
  • Nobody–industry, regulators or retailers—wants to bother.
  • The U.S. food safety system is too fractured; no federal agency has the authority to mandate such reforms.
  • USDA food safety authority only starts at the slaughterhouse, not the farm.

An impressive number of excuses, no?

Better make sure you handle chicken as if it were radioactive and cook it thoroughly.

This series is well worth a read if you want to understand what’s wrong with our food safety system.

More on catfish inspection (absurdly enough)

My post yesterday about the politics of catfish inspection inspired comments that I need to better appreciate the superiority of USDA’s import safety program, which requires this checklist for steps that must be taken by importers of meat, poultry, or processed egg products:

  1. Products must originate from certified countries and establishments eligible to export to the United States.
  2. The Animal and Plant Health Inspection Services (APHIS) restricts some products from entering the United States because of animal disease conditions in the country of origin (see APHIS Veterinary Services, National Center for Import and Export).
  3. Countries and establishments become eligible following an equivalence determination process by FSIS.
  4. Imported products must meet the same labeling requirements as domestically-produced products.
  5. After filing the necessary forms for U.S. Customs and Border Protection, and meeting animal disease requirements of APHIS, all imported meat, poultry and processed egg products must be presented for inspection by FSIS at an official import establishment.

It’s not surprising if USDA’s import safety system is better than the FDA’s.  USDA gets $14 million a year to run its currently non-operating catfish inspection system.  The FDA gets $700,000 and, according to the Government Accountability Office, has managed pretty well with it (see yesterday’s post).

Definition is also an issue.  USDA rules apply to all catfish species.  But to protect American catfish producers, the FDA defined catfish as the North American species.  But Vietnam produces different species, which makes catfish inspection even weirder.

Although FDA has had some problems with seafood inspection, it is generally responsible for dealing with fish safety and has had seafood HACCP requirements in place since the mid-1990s.  The USDA does not have authority over fish; it is responsible for the safety of meat and poultry.

Why should catfish be an exception?

Why are we even talking about which agency should be in charge of inspecting catfish?

If the politic fuss over catfish inspection reveals anything, it is why we so badly need a single food safety agency—one that combines and integrates the food safety functions of USDA and FDA—to ensure the safety of the American food supply.

Addition, November 28: Members of Congress urge repeal of the USDA’s catfish inspection program.

The hooks and lines of the farm bill: Catfish inspection

As I am endlessly complaining, the farm bill is so detailed, complicated, and opaque that no rational person can possibly understand it, let alone a member of Congress.

To wit: catfish inspection.

As Gail Collins noted in her New York Times column a week or so ago, some members of the House want the USDA to inspect catfish, not the FDA (which ordinarily is responsible for fish inspection).  The current FDA inspection office costs $700,000 per year.  The USDA office, established by the 2008 farm bill, costs about $14 million a year, even though the USDA has not gotten around to issuing rules or actually inspecting catfish.

What is this about?  Not fish safety, really.  It’s about protecting catfish farmers in the South and setting up “more rigorous” safety criteria that will exclude competitive foreign catfish imports, especially from Vietnam.

The House version of the farm bill calls for repeal of USDA catfish inspection as a cost-cutting measure (the Senate farm bill does not mention catfish inspection, which means it leaves the USDA office in place).

Thad Cochran, Republican Senator from Mississippi, wants the House to delete the repeal provision, keep USDA in charge, and, thereby, protect the Mississippi catfish industry from foreign catfish imports.

Politico Pro quotes a member of Cochran’s staff:

Sen. Cochran has made it clear that his priority is to complete the new farm bill and get it signed into law. It sounds like there are some who have a deep under-appreciation of the diversity of Mississippi’s agriculture industry and the importance of this bill to the state’s farmers, foresters, hunters, and those in need of nutrition assistance.

The New York Times also points out that although some watchdog consumer groups support tougher safety standards for catfish (because of lower foreign standards for antibiotics and other chemicals), a Government Accountability Office report in May 2012 called imported catfish a low-risk food and said an inspection program at the Agriculture Department would “not enhance the safety of catfish.”

Now, says the Times in another article, a coalition of budget watchdog groups and a seafood trade group are lobbying to repeal the USDA’s inspection program.

All of this is in the House version of the farm bill, but unless you are a lobbyist for the catfish industry, you would never know it from the bill itself.  Here’s the relevant section from the  House bill.

catfish

As Gail Collins puts it,

See, this is what I like about the farm bill. The agriculture parts harken back to the golden era when Republicans and Democrats could work together to promote stupid ideas that benefited the special interests in their districts. And then go out and get inebriated in bipartisan drinking sessions. Now everybody is in the gym and then shutting down the government.
