According to the FDA and CDC, Whole Genome Sequencing (WGS) analysis shows that samples from sick people in this investigation are closely related genetically to a sample collected in 2010 from the environment at J.M. Smucker Company’s facility in Lexington, Kentucky, where Jif brand peanut butter is produced.  However, NCBI data seems to indicate that this problem has been long ongoing.  What happened in 2014?

Since the last update on May 21, 2022, two more illnesses have been reported. As of May 25, 2022, a total of 16 people infected with the outbreak strain of Salmonella Senftenberg have been reported from 12 states:  Arkansas (1), Georgia (2), Illinois (1), Massachusetts (1), Missouri (2), Ohio (1), North Carolina (2), New York (1), South Carolina (1), Texas (2), Virginia (1), and Washington (1).

According to the CDC, for every one person who is a stool-culture confirmed positive victim of Salmonella in the United States, there is a multiple of 38.5 who are also sick but remain uncounted. (See, AC Voetsch, “FoodNet estimate of the burden of illness caused by nontyphoidal Salmonella infections in the United States,” Clinical Infectious Diseases 2004; 38 (Suppl 3): S127-34).

Illnesses started on dates ranging from February 19, 2022, through May 2, 2022. Sick people range in age from less than one to 85 years, with a median age of 51, and 73% are female. Of nine people with information available, two have been hospitalized. No deaths have been reported.

The true number of sick people in an outbreak is likely much higher than the number reported, and the outbreak may not be limited to the states with known illnesses. This is because many people recover without medical care and are not tested for Salmonella. In addition, recent illnesses may not yet be reported as it usually takes 2 to 4 weeks to determine if a sick person is part of an outbreak.

State and local public health officials are interviewing people about the foods they ate in the week before they got sick. Of the 10 people interviewed, 10 (100%) reported eating peanut butter. Of the nine sick people with brand information, all nine (100%) reported eating Jif brand peanut butter.

On May 20, 2022, J.M. Smucker Company recalled multiple Jif brand peanut butter types. Additional companies have recalled food items made with Jif brand peanut butter. Do not eat, sell, or serve recalled foods.
