CDC weighs in on Salmonella Newport Outbreak tied to JBS Tolleson

As of October 4, 2018, 57 people infected with the outbreak strain of Salmonella Newport have been reported from 16 states. A list of the states and the number of cases in each can be found on the Map of Reported Cases page.

Illnesses started on dates ranging from August 5, 2018, to September 6, 2018. Ill people range in age from less than one year to 88, with a median age of 33. Sixty-one percent are male. Of 45 people with information available, 14 (31%) have been hospitalized. No deaths have been reported.

Illnesses might not yet be reported due to the time it takes between when a person becomes ill and when the illness is reported. This takes an average of 2 to 4 weeks. Please see the Timeline for Reporting Cases of Salmonella Infection for more details.

Epidemiologic and traceback evidence indicates that ground beef produced by JBS Tolleson, Inc. of Tolleson, Arizona, is a likely source of this outbreak.

In interviews, ill people answered questions about the foods they ate and other exposures in the week before they became ill. Thirty-six (92%) of 39 people interviewed reported eating ground beef at home. This percentage is significantly higher than results from a survey[PDF – 787 KB] of healthy people in which 40% of respondents reported eating any ground beef at home in the week before they were interviewed.  Also, several ill people ate ground beef at the same events or purchased ground beef at the same grocery store chains. When several unrelated ill people ate at the same event or shopped at the same store within several days of each other, it suggests that the contaminated food item was served or sold there.

USDA-FSIS and state partners traced the source of the ground beef eaten by ill people in this outbreak to JBS Tolleson, Inc. On October 4, 2018, JBS Tolleson, Inc. recalled approximately 6.5 million pounds of beef products that may be contaminated with Salmonella Newport.
