Food Safety and Ground Turkey

  • Don’t eat raw or undercooked ground turkey.
  • Cook ground turkey burgers and mixtures such as casseroles to 165°F internal temperature. Use a food thermometerexternal icon to make sure the meat has reached a safe internal temperature. You can’t tell whether meat is safely cooked by looking at it.
    • For turkey burgers, insert thermometer through the side of the patty until it reaches the middle.
    • Place the thermometer in the thickest part of the meat for other items.
  • Ask that ground turkey burgers and mixtures be cooked to 165°F internal temperature when ordering at a restaurant.
  • Wash hands and items that came into contact with raw ground turkey—including countertops, utensils, dishes, and cutting boards—with soap and water.
Symptoms of Salmonella Infection

  • Most people infected with Salmonella develop diarrhea, fever, and stomach cramps 12 to 72 hours after being exposed to the bacteria.
  • The illness usually lasts 4 to 7 days, and most people recover without treatment.
  • In some people, the diarrhea may be so severe that the patient needs to be hospitalized. Salmonella infection may spread from the intestines to the bloodstream and then to other places in the body.
  • Children younger than 5 years, adults older than 65 years, and people with weakened immune systems are more likely to have a severe illness.
Investigation Details

May 7, 2019

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

Public health investigators used the PulseNet system to identify illnesses that may have been 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 related genetically. This means that ill people in this outbreak were more likely to share a common source of infection.

As of May 7, 2019, a total of 7 people infected with the outbreak strain of Salmonella Schwarzengrund were reported from 3 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 December 19, 2018, to March 16, 2019. Ill people ranged in age from less than one year to 71, with a median age of 46. Eighty-six percent were female. One (14%) person was hospitalized. No deaths were reported.

Whole genome sequencing (WGS) analysis of 5 isolates from ill people and 4 isolates from turkey predicted antibiotic resistance to ampicillin (n=2), gentamicin (n=2), streptomycin (n=2), sulfisoxazole (n=9), and tetracycline (n=9). One additional clinical isolate had no resistance. Testing of 2 outbreak isolates using standard antibiotic susceptibility testing by CDC’s National Antimicrobial Resistance Monitoring System (NARMS) laboratory confirmed these results. This resistance likely will not affect the choice of antibiotic used to treat most people.

Investigation of the Outbreak

Epidemiologic and laboratory evidence indicated that ground turkey produced by Butterball, LLC in Mount Olive, North Carolina was the likely source of this outbreak.

Health officials collected information about the foods ill people ate and other exposures they had in the week before they became ill. Five (71%) of 7 ill people either lived in a residence where ground turkey was served, or reported eating ground turkey at home.

Health officials in Wisconsinexternal icon collected records and unopened ground turkey from a residence where four of the ill people live. Records indicated that the turkey used at the residence was Butterball brand ground turkey.

The outbreak strain of Salmonella Schwarzengrund was identified in samples of the ground turkey collected from the residence where four ill people live. These results provided more evidence that people in this outbreak got sick from eating ground turkey products produced by Butterball, LLC.

On March 13, 2019, Butterball, LLC recalledexternal icon approximately 78,164 pounds of ground turkey products that may be contaminated with Salmonella Schwarzengrund.

As of May 7, 2019, this outbreak appears to be over.
