The USDA is at long last giving some attention—a small but significant first step—to reducing Salmonella contamination of poultry products.

Salmonella is a big problem in poultry and eggs.  For decades, food safety advocates have called on the USDA to declare Salmonella an adulterant.  Adulterated food is illegal to sell.

The poultry industry has resisted, arguing that chicken gets cooked before it is eaten; cooking kills Salmonella.

It does, but you don’t want toxic forms of Salmonella in your kitchen where they can get into other foods.  For background all this, see my book, Safe Food: The Politics of Food Safety.

In a press release, the USDA’s Food Safety and Inspection Service (FSIS) announces that it

is considering a regulatory framework for a new strategy to control Salmonella in poultry products and more effectively reduce foodborne Salmonella infections linked to these products…The most recent report from the Interagency Food Safety Analytics Collaboration estimates that over 23% of foodborne Salmonella illnesses are attributable to poultry consumption—almost
17% from chicken and over 6% from turkey.

The proposed Salmonalla framework has three components:

What FSIS is actually doing:

We will publish a proposed notice of determination to declare Salmonella an adulterant in NRTE [not ready to eat] breaded and stuffed chicken products in 2022, and we intend to publish additional proposed rules and policies implementing this strategy in 2023, with the goal of finalizing any rules by mid-2024.

The adulterant consideration only applies to breaded and stuffed chicken or turkey products that are likely to be microwaved but not necessarily thoroughly cooked.  It does not apply to plain, unbreaded and unstuffed poultry.

Consumer Reports finds lots of poultry to be contaminated with Salmonella.  Consumer Reports says Salmonella is “lethal but legal.”

Currently, a chicken processing facility is allowed to have salmonella in up to 9.8 percent of all whole birds it tests, 15.4 percent of all parts, and 25 percent of ground chicken. And producers that exceed these amounts are not prevented from selling the meat. If salmonella became an adulterant, even in some poultry products, it would help reduce the amount of contaminated meat that hits the market.

As might be expected, the National Chicken Council opposes the USDA’s proposed framework: “lacks data, research.”

the facts show that the Centers for Disease Control and FSIS’s own data demonstrate progress and clear reductions in Salmonella in U.S. chicken products.  “Increased consumer education about proper handling and cooking of raw meat must be part of any framework going forward…Proper handling and cooking of poultry is the last step, not the first, that will help eliminate any risk of foodborne illness. We’ll do our part to promote safety.”

A report from the U.S. Public Interest Research Group (PIRG) says that USDA recalls of meat and poultry have nearly doubled since 2013.

• USDA posts its recalls and notices here.

The PIRG report says FDA recalls of the products it regulates—produce, seafood, and processed foods—have dropped.  The Food Safety Modernization Act rules are in effect, and working.

• FDA posts its recalls and notices here.

To do something about meat and poultry recalls, some of which involve Salmonella, food safety lawyer Bill Marler along with  Consumer Reports and other advocacy groups, have petitioned USDA to classify Salmonella as an adulterant, an action that is long overdue (see the Washington Post’s story on Marler’s action.

Does USDA have the authority to do this?  I think yes, even though courts have ruled that because Salmonella can be killed by cooking, they are a natural contaminant.

Yes, but supermarket raw chicken is frequently contaminated with Salmonella and frequently associated with disease outbreaks.

Salmonella-contaminated chicken requires special handling in kitchens: Don’t wash it!  Keep it entirely separate from all other foods.  Don’t put it on counters, plates, or cutting boards that can come in contact with other foods.   In other words, run your kitchen like a maximum security laboratory.

It’s high time the USDA did something about this one.

As readers of this blog should know by now, I’m a big fan of food safety lawyer Bill Marler, whose blog keeps me up to date on food safety matters.

He posted recently on a Salmonella outbreak caused by contact with backyard chickens.

The CDC keeps track of such things.  By its count,

A total of 279 people infected with the outbreak strains of Salmonella have been reported from 41 states.

• 40 (26%) people have been hospitalized and no deaths have been reported.
• 70 (30%) people are children younger than 5 years.

The CDC’s advice:

I was interested in Marler’s account because I knew that he had backyard chickens at his place near Seattle.

Here’s what he says about that:

We have had hens in our backyard since just after the DeCoster egg debacle in 2010.  I clean the chicken house about twice a month and the shoes and clothes I wear are removed before going inside.  I wear a mask and gloves when I clean and either wash my hands well or take a shower.  I do not pick up the chickens unless they are ill, and I wash my hands after I do.  I wash the eggs and refrigerate then.  They tend to get used within the week.

I do my best to think about the possibility of cross-contamination with Salmonella and/or Campylobacter.  So far, so good.

Good advice.

I wrote about the recall of Honey Smacks cereals last June when its Salmonella outbreak was just past its peak, but a post from food-safety lawyer Bill Marler made me think this outbreak is worth another look.

The CDC says the Honey Smacks outbreak is over now.  But it also says you should still be careful not to eat Honey Smacks with a “best if used by” date of June 14, 2019 or earlier (the packages I saw on the shelf at the Ithaca Wegmans were dated May 19, 2019—oops).

Marler got my attention by pointing out what the FDA found in its June 2018 investigation and reported in its warning letter to Kerry, Inc, the manufacturer of this Kellogg’s cereal.

Between September 29, 2016 and May 16, 2018, you repeatedly found Salmonella throughout your facility, including in cereal production rooms. During this time period, you had 81 positive Salmonella environmental samples and 32 positive Salmonella vector samples (samples taken in response to finding a positive on routine testing)…Further, you had repeated findings of other Salmonella species in some production lines and rooms used for the manufacture of cereal.

What?  Over a period of a year and a half, the manufacturer’s testing identified 113 samples positive for Salmonella—and did little or nothing to prevent Salmonella from getting into the cereal?

The damage was hardly trivial.The Food Safety and Modernization Act set rules governing the safe production of foods.  Clearly, some companies, this one apparently, did not bother to follow them.

This, then, is a matter of inadequate enforcement.

Do food companies need to be forced to follow standard food safety procedures?  Apparently so if public health is to be protected.

I am baffled by food safety issues related to the recent recall of Ritz Crackers and Goldfish by their manufacturers, Mondelēz and Campbell/Pepperidge, respectively.

I understand how their whey protein ingredient could be contaminated by Salmonella.  Whey is an excellent growth medium for bacteria.

What I don’t understand is how people eating Ritz Crackers or Goldfish could become ill with Salmonella (the New York Times reports two cases of illness).

Aren’t crackers baked?  Isn’t that a kill step?

I can understand why Mondelēz would issue a recall as a precautionary measure.

But can someone please explain to me how Ritz Crackers or Goldfish could contain live Salmonella from whey baked into them?

I am not the only one puzzled by this.  BakeryAndSnacks.com quotes Stewart Eton, an industry food safety official, who emphasizes that baked goods undergo a kill step.

This would ordinarily be a CCP [Critical Control Point] under their HACCP [hazard analysis and control plan] program with the process validated and verified at regular intervals.  Under the FSMA [FDA’s food safety laws], for example, this risk-based rationale would be deemed sound and would not require a recall.

What’s going on here?

A possible explanation

A reader writes that flavoring agents are sprayed on to Goldfish after they are baked.  If this is true, Goldfish would be make in the same way as dry pet foods and would not be sterile.

The CDC tracking of the papaya outbreak continues, with a score of

• Case Count: 173
• States: 21
• Deaths: 1
• Hospitalizations: 58
• Recall: Yes

All foodborne illness outbreaks are devastating for victims but fascinating for investigators, since each is different.

This investigation has traced the illness-causing Salmonella to one kind of papaya (Maridol, under Caribeña, Cavi, and Valery brands) to one Mexican farm (Carica de Campeche).

But four Salmonella strains have been found in papaya samples and in ill people:

• Kiambu
• Thompson
• Agona
• Gaminara

The shift from one to another is evident in the epi curve:

The moral:

• Don’t buy Maridol papayas.
• If you have one, throw it away (but be careful not to cross contaminate surfaces)
• If you don’t know where the papaya was grown, don’t eat it

If you are interested in the legal implications, check Bill Marler’s website.

The latest Salmonella outbreak comes courtesy of Pacific Coast Fruit Company, which produces Taylor Farms Organic Power Greens Kale Medley.

Alas, Salmonella do not care whether or not vegetables are USDA Certified Organic—even kale.

Coral Beach discusses the details of the investigation into this outbreak at Food Safety News this morning.

And food safety lawyer Bill Marler has some pointed questions about this outbreak.

•  Why no announcement of the Salmonella Enteritidis outbreak?
•  Why no recall of the product?
•  Given that the product was distributed nationwide, are we seeing a spike in Salmonella Enteritis cases in states other than Minnesota?
• Why was the announcement removed from Pacific Coast Fruit Website?

He also has plenty to say about what another recent outbreak (this one due to frozen vegetables contaminated with Listeria) tells us about what is and what is not working in our current food safety system.

His essay makes the point that foodborne illness outbreaks due to contaminated meat are becoming increasingly rare.  Most current outbreaks are due to contaminated vegetables.

How come?  For meat, the system is working.

• Regulation: prevention controls on meat and poultry went into effect in the mid-1990s.
• The CDC’s ability to track outbreaks is good and getting better, thanks to genetic fingerprinting.
• Government agencies are doing more testing.
• The US Attorney’s office has shown interest in “finding companies and their CEOs criminally responsible for manufacturing tainted foods.  Lawsuits and jail time have a unique ability to make companies pay attention.”
• Recalls are “both disruptive and expensive.”
• Publicity about recalls discourages the public from buying similar products.

In sum, “recall costs, slumping sales, along with civil and criminal liability, are powerful market incentives.   The FDA Food Safety Modernization Act (FSMA) should help once companies start following its regulations.

He ought to know.  When Congress was foot-dragging on passing FSMA, Marler sent every member of Congress a tee shirt with this image:

He better be careful.  If he’s right about market forces cleaning up food safety problems, he may get his wish.

But we still have a long way to go on vegetable safety, apparently.

I’m fascinated by reports of Chipotle’s ongoing problems with foodborne illness.

• The main interest of the press in these episodes is their effect on Chipotle’s stock prices.
• The outbreaks have been linked to a bunch of different pathogens: E. coli O157:H7, E. coli STEC O26, Salmonella, norovirus, and, possibly, hepatitis A.  This means they are due to different causes at different outlets.
• The food, foods, or individuals responsible for these outbreaks are uncertain, making them hard to know how to prevent.
• Hence: conspiracy theories.

The outbreaks

The most recent CDC report (December 21) counts 53 cases of E. coli 026 from 9 states, with 20 hospitalizations.

The FDA reports (December 22) that there are 5 more recent cases of illness caused by a different type of E. coli 026 among people eating at Chipotle.

Food Safety News summarizes the previous Chipotle outbreaks.

• Seattle: July 2015, 5 people sick from E. coli O157:H7, from unknown food source.
• Simi Valley, CA: August 2015, more than 230 sick from norovirus (most likely from an ill worker).
• Minnesota: August and September 2015, 64 people sick from Salmonella Newport (tomatoes?).
• Boston: December 2015, at least 136 people sick from norovirus.

The consequences

• Nearly 500 people have become ill after eating in a Chipotle since July this year.
• Stock prices are down 30 percent from a high of $757.77 in August.

The conspiracy theory

The title says it all: “ANALYSIS: Chipotle is a victim of corporate sabotage… biotech industry food terrorists are planting e.coli in retaliation for restaurant’s anti-GMO menu.”

I don’t think so.

You don’t need conspiracy theories to explain poorly designed and executed food safety procedures.

What is to be done?

The New York Times attributes the inability to identify the food source to Chipotle’s record-keeping:

One of the challenges here has been that we have been able to identify the restaurants where people ate, but because of the way Chipotle does its record-keeping, we have been unable to figure out what food is in common across all those restaurants,” said Dr. Ian Williams, chief of the outbreak response and prevention branch of the C.D.C.

That, at least, should be an easy fix.

For the rest, Chipotle has initiated a new food safety program, and has recruited a leading food safety expert, Mansour Samadpour, to set it up.  I met Samadpour at Earthbound Farms when he was helping that company prevent further problems after the spinach outbreak of 2006.  He knows what he his doing.

Chipotle needs to follow his advice—in letter and in spirit.

Food safety lawyer Bill Marler advises Chipotle to follow a 12-step program to create an effective culture of food safety from top down and bottom up within the company.  For example, he advises the company’s CEO, Steve Ells to say:

• It is time to have a culture of food safety added to the “integrity” of the food. I have now learned that bacteria and viruses do not care a whit if my food’s ingredients are organic, sustainable, non-GMO and humanely raised.
• I am going to hire a vice-president of Food Safety. That person will report directly to me and to the Board of Directors. Like Dave Theno being brought in to address the Jack-in-the-Box crisis of 1993, this person will have the resources and access to decision makers to create a culture of food safety from the top down.
• The company’s new mantra – “Safe Food with Integrity” – will be completely transparent and shared with all – including our competitors.

Will Ells take his advice?  I hope so.
