Jif Salmonella outbreak much larger than reported by CDC

In the weeks and months following the May 20, 2022, recall of Jif peanut butter products, the US Food and Drug Administration (FDA) received more than 200 reports from consumers complaining of illness after consuming the recalled products.

This information was supplied to eFoodAlert by the FDA in response to a Freedom of Information Act request.

In comparison, the US Centers for Disease Control and Prevention (CDC) reported just twenty-one confirmed cases of Salmonella Senftenberg linked to consumption of Jif peanut butter.

It is usual for an outbreak of foodborne illness to be significantly larger than indicated by CDC statistics. Indeed, the CDC reminded the public of this in its investigation report, saying, “The true number of sick people in this outbreak was likely much higher than the number reported. This is because many people recover without medical care and are not tested for Salmonella.”

By the numbers

The CDC tally

The CDC received lab-confirmed reports of outbreak cases in 21 individuals from 17 different states. Four people were hospitalized.

  • The first victim (“Patient Zero”) became ill on February 19, 2022.
  • The 21st victim became ill on May 23, 2022.
  • The youngest victim was less than one year old.
  • The oldest victim was 85 years old.
  • The median age of the victims was 59 years.
  • 75% of the victims were female.
  • 100% of the victims interviewed reported having consumed Jif peanut butter in the days before becoming ill.

The FDA tally

From January 1, 2022, through October 11, 2022, the FDA fielded a total of 320 queries and complaints relating to Jif peanut butter. Of these, 319 were specifically related to products manufactured at the Lexington, Kentucky, manufacturing plant linked to the outbreak.

  • 235 of the complainants reported having suffered an illness after consuming Jif peanut butter
  • 204 of the complainants reported specific symptoms; the remaining 31 reports mentioned “illness” or “adverse events”
  • Most of the individuals who reported symptoms suffered from multiple ill effects, including:
    • diarrhea: 166
    • cramps or abdominal pain: 124
    • vomiting: 80
    • nausea: 67
    • fever or chills: 63
    • Weakness, lethargy or fatigue: 33
    • headache: 31
    • Fainting, disorientation, dizziness, brain fog: 10
  • 8 reported bloody diarrhea
  • 4 reported a confirmed Salmonella diagnosis
  • 2 suffered from colitis
  • 2 suffered sepsis (a potentially serious, more generalized infection)
  • 1 individual reported a perforated bowel and peritonitis
  • 1 reported kidney failure

The recall

On May 20, 2022, The J.M. Smucker Co. announced a voluntary recall of peanut butter manufactured at its Lexington, Kentucky, production facility during a period of several months, up to and including the recall date.

The recall notice listed a variety of products and packaging formats from individual serving size packets weighing less than one ounce to 96-ounce twin packs, including:

As of October 21, 2022, the recall has not been completed.

The takeaways

CDC versus FDA reporting

The differences between the data reported by the FDA and the CDC are a function of how the two agency systems operate.

The CDC relies on reports of lab-confirmed cases of foodborne illness, and reports only on those cases, whereas the FDA receives and tabulates complaints from consumers, regardless of whether or not there was lab confirmation of an infection.

Both systems provide useful and complementary information that enables epidemiologists to determine the scope of an outbreak and–with a bit of luck thrown in to season the pot–trace it to its source.

In fact, it is likely that the number of people affected by the contaminated peanut butter was far larger even than the 200+ individuals reported by the FDA. There is no way of knowing how many people suffered mild symptoms and either didn’t realize they were linked to a Jif product or didn’t bother making a report.

The consequences for the company

In 2006, Peter Pan peanut butter manufactured by ConAgra was responsible for an outbreak of 425 Salmonella infections. An FDA inspection revealed that the company had been aware of a Salmonella contamination problem in their production plant, but did not reveal this information to the FDA investigation team. The government laid charges against ConAgra and entered into a plea agreement with the company in 2015. ConAgra pled guilty to a criminal misdemeanor, was fined $8 million, and had to forfeit an additional $3.2 million in assets.

In 2009, Peanut Corporation of America was responsible for a deadly outbreak of Salmonella infections that sickened 714 people and killed nine of them. Company management had knowingly shipped contaminated peanut butter to its customers. Once again, the government brought criminal charges. This time, the owners received prison sentences.

In 2012, Sunland Inc., the largest producer of organic peanut butter in the USA, was the source of a Salmonella outbreak that sickened 42 people. Again, the coupany was found to have knowingly shipped contaminated product. The FDA suspended Sunland’s food facility registration, effectively shutting down the company’s operations, but no charges were laid.

Earlier today, the FDA declined eFoodAlert’s request for a copy of the Jif Establishment Inspection Report on the basis that, “…disclosure could reasonably be expected to interfere with enforcement proceedings.”

The FDA has a range of possible enforcement proceedings at its disposal, ranging from a simple Warning Letter all the way up to referring the case to the Department of Justice for the laying of criminal charges.

Duncan Hines cake mixes recalled; may be linked to outbreak investigation

Recalled Duncan Hines cake mixes

Conagra Brands is recalling four Duncan Hines brand cake mixes after Salmonella Agbeni was found in a retail sample of Duncan Hines Classic White cake mix.

According to the recall notice, the isolate may be linked to a cluster of five Salmonella illnesses currently under investigation by FDA and CDC. No information has been released as yet regarding the geographic distribution of the illnesses.

The FDA is conducting an inspection at the Conagra Brands-owned manufacturing facility that produced the cake mixes. The FDA is also collecting environmental and product samples.

Several of the individuals reported consuming a cake mix at some point prior to becoming ill, and some may have also consumed these products raw and not baked.

The list of recalled products includes:

  • Duncan Hines Classic White Cake (15.25oz; UPC 644209307500; Best if used by MAR 7 2019, MAR 8 2019, MAR 9 2019, MAR 10 2019, MAR 12 2019, MAR 13 2019)
  • Duncan Hines Classic Yellow Cake (15.25oz; UPC 644209307494; Best if used by MAR 9 2019, MAR 10 2019, MAR 12 2019, MAR 13 2019)
  • Duncan Hines Classic Butter Golden Cake (15.25oz; UPC 644209307593; Best if used by MAR 7 2019, MAR 8 2019, MAR 9 2019)
  • Duncan Hines Signature Confetti Cake (15.25oz; UPC 644209414550; Best if used by MAR 12 2019, MAR 13 2019)

The products listed above were distributed for retail sale in the U.S. and limited international exports.

Salmonella can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems. Healthy persons infected with Salmonella often experience fever, diarrhea (which may be bloody), nausea, vomiting and abdominal pain. In rare circumstances, infection with Salmonella can result in the organism getting into the bloodstream and producing more severe illnesses such as arterial infections (i.e., infected aneurysms), endocarditis and arthritis.

What should retailers and restaurants do?

Retailers should not sell and should discard all recalled products.

Retailers, restaurants, and other food service operators should always practice safe food handling and preparation measures. It is recommended that they wash hands, utensils, and surfaces with hot, soapy water before and after handling food.

  • Wash and sanitize display cases and refrigerators regularly.
  • Wash and sanitize cutting boards, surfaces, and utensils used to prepare, serve, or store food.
  • Wash hands with hot water and soap following the cleaning and sanitation process.
  • Regular frequent cleaning and sanitizing of food contact surfaces and utensils used in food preparation may help to minimize the likelihood of cross-contamination.

What should consumers do?

The FDA is advising consumers not to bake with or eat any recalled cake mix. If already purchased, consumers should throw it away or return to the place of purchase for a refund.

Consumers should always practice safe food handling and preparation measures. It is recommended that they wash hands, utensils, and surfaces with hot, soapy water before and after handling food.

FDA offers these tips for safe food handling to keep you and your family healthy:

  • Do not eat any raw cake mix, batter, or any other raw dough or batter product that is supposed to be cooked or baked.
  • Wash hands, work surfaces, and utensils thoroughly after contact with flour and raw batter or dough products.
  • Keep raw foods separate from other foods while preparing them to prevent any contamination that may be present from spreading. Be aware that flour or cake mix may spread easily due to its powdery nature.
