Millions of pounds of meat recalled amid outbreaks

Johnston County Hams recently issued a recall of nearly 90,000 pounds of ready-to-eat ham products. Now, a number of products — ranging from country ham biscuits to a whole boneless glazed ham with brown sugar — are being recalled. Health officials say four people have been infected with the outbreak strain of listeria, all of whom who were hospitalized and one of whom died. Meanwhile, Arizona company JBS Tolleson recalled more than 6.5 million pounds of beef that might be contaminated from salmonella. Health officials said 57 people from 16 states have been sickened in that incident.

Investigation Details

October 4, 2018

CDC, public health and regulatory officials in several states, and the U.S. Department of Agriculture’s Food Safety and Inspection Service (USDA-FSIS) are investigating a multistate outbreak of Salmonella Newport infections.

Public health investigators are using the PulseNet system to identify illnesses that may be part of this outbreak. PulseNet is the national subtyping network of public health and food regulatory agency laboratories coordinated by CDC. DNA fingerprinting is performed on Salmonella bacteria isolated from ill people by using techniques called pulsed-field gel electrophoresis (PFGE) and whole genome sequencing (WGS). CDC PulseNet manages a national database of these DNA fingerprints to identify possible outbreaks. WGS gives a more detailed DNA fingerprint than PFGE. WGS performed on bacteria isolated from ill people showed that they were closely relatedly genetically. This means that people in this outbreak are more likely to share a common source of infection.

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.

Investigation of the Outbreak

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.

This investigation is ongoing, and CDC will provide updates when more information is available.
