JACKSON, Wyo. \u2014 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. At least 16 cases have been identified among Wyoming residents so far, with at least 396 cases, nationally. Wyoming cases have been reported so far from Campbell, Carbon, Crook, Goshen, Natrona, Sheridan, and Teton counties with half of the outbreak-associated cases from Campbell County. \u201cPeople ill in connection to this outbreak described eating raw onions in freshly prepared foods, including salads, sandwiches, wraps, salsas, and dips,\u201d said Tiffany Greenlee, surveillance epidemiologist with WDH. \u201cThat\u2019s why we\u2019re recommending residents should not eat, serve or sell any onions from Thomson International Inc. or products made with these onions.\u201d Advice from Greenlee also includes: \tCheck refrigerators and kitchens for potentially affected onions or fresh foods made with them. \tCheck packages or look for stickers on an onion to see if it is from Thomson International, Inc. If it is, don\u2019t eat it. Throw it away. \tOther brand names that may be on labels include Thomson Premium, TLC Thomson International, Tender Loving Care, El Competitor, Hartley\u2019s Best, Onions 52, Majestic, Imperial Fresh, Kroger, Utah Onions, and Food Lion. \tIf you can\u2019t tell where onions are from, don\u2019t eat them. Throw them away. \tLook for foods with onions and do not eat them if it\u2019s unknown where onions came from. Throw them away, even if no one got sick. \tWash and sanitize any surfaces that may have come in contact with onions or their packaging, such as countertops, refrigerator drawers, knives, and cutting boards. According to the Centers for Disease Control and Prevention (CDC): \tMost people infected with Salmonella develop diarrhea, fever, and stomach cramps 6 hours to 6 days after being exposed to the bacteria. \tThe illness usually lasts 4 to 7 days, and most people recover without treatment. \tIn 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. \tChildren younger than 5 years, adults 65 years and older, and people with weakened immune systems are more likely to have a severe illness.
