Wyoming Department of Health: At least 16 Salmonella infections in 7 counties


CASPER, Wyo. — The Wyoming Department of Health said on Monday, Aug. 3 that at least 16 Salmonella Newport infections linked to eating red onions have been identified among Wyoming residents.

That is up five from the 11 Wyoming cases the United States Food & Drug Administration, who reported 396 cases nationally, reported in a recall announcement for a variety of onion products from California-based Thomson International, Inc.

“With a growing outbreak of Salmonella Newport infections linked to eating red onions, the Wyoming Department of Health (WDH) is encouraging caution among state consumers,” the WDH said.

Half of Wyoming’s cases associated with the outbreak have been reported in Campbell County, the WDH said. Cases have been identified in the following counties:

  • Campbell
  • Carbon
  • Crook
  • Goshen
  • Natrona
  • Sheridan
  • Teton

“People ill in connection to this outbreak described eating raw onions in freshly prepared foods, including salads, sandwiches, wraps, salsas and dips,” WDH Surveillance Epidemiologist Tiffany Greenlee said. “That’s why we’re recommending residents should not eat, serve or sell any onions from Thomson International Inc. or products made with these onions.”

Greenlee provides the following advice to people in the WDH release:

  • Check refrigerators and kitchens for potentially affected onions or fresh foods made with them.
  • Check packages or look for stickers on an onion to see if it is from Thomson International, Inc. If it is, don’t eat it. Throw it away.
  • If you can’t tell where onions are from, don’t eat them. Throw them away.
  • Look for foods with onions and do not eat them if it’s unknown where onions came from. Throw them away, even if no one got sick.
  • Wash and sanitize any surfaces that may have come in contact with onions or their packaging, such as countertops, refrigerator drawers, knives and cutting boards.

The WDH also added advise from the Centers for Disease Control and Prevention (CDC):

  • Most people infected with Salmonella develop diarrhea, fever and stomach cramps 6 hours to 6 days after being exposed to the bacteria.
  • The illness usually lasts 4 to 7 days, and most people recover without treatment.
  • In some people, the illness 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 65 years and older and people with weakened immune systems are more likely to have a severe illness.
