2013 Salmonella Newport Infections Associated with Beef, Minnesota and Wisconsin

In June 2013, the Minnesota Department of Health (MDH) Public Health Laboratory (PHL) determined that a clinical Salmonella Newport isolate submitted through routine surveillance had an indistinguishable PFGE pattern to 7 clinical isolates in Wisconsin. Eventually 12 cases were identified in Minnesota with illness onsets ranging from June 3 to July 17. Upon initial interview, 9 cases in Minnesota reported attending a gathering in the week prior to illness onset. The gatherings occurred from June 1 to July 21. Eight cases reported consuming beef at the gatherings, 6 reported that other gathering attendeees were ill, and 4 specifically reported consuming private kill beef that was purchased from a farm. Limited cooperation by cases in providing contact information for other ill gathering attendees and/or gathering hosts prevented further investigation of each gathering. Two sibling cases attending a gathering at a private residence in St. Paul, Minnesota on July 3. Their parents reported that a cow was purchased from a farm, butchered by the host, an served as beef larb, a raw beef dish. The parents were unable to identify where the cow as purchased and refused to provide contact information for the gathering host or other ill attendees. A laboratory confirmed case from Wisconsin also attended the July 3rd gathering. Another case attended a family gathering in Brooklyn Center on July 21. This person reported that a cow was purchased from a farm, butchered, and served as beef larb at the gathering and that other attendees were ill. The case reported consuming the beef but would not provide contact information for the host of the gathering, the individual who purchased the cow, or other ill attendees. One case attended a graduation party at a neighbor's house on July 13. They reported consuming beef larb. This person cooperated with investigators and provided contact information for the party host. The host reported that a whole cow was purchased from a farm in Forest Lake, MN. They reported that the farmer killed the cow and that the family butchered the cow on the farm before transporting it back to their home for further processing. The host provided leftover diced beef, liver and meat for laboratory testing. All three leftover items tested positive for Salmonella Newport with the outbreak strain. The Minnesota Department of Agriculture visited the farm where the cow was purchased. The farmer reported purchasing 12 Jersey steers from Wisconsin in mid-June. Six of the 12 steers died. Wisconsin Department of Agriculture contacted the person who sold the cows. He purchased the steers from an auction barn in Stratford, Wisconsin on June 19. The 12 steers were from 4 different Wisconsin farms. As a result of this investigation, the farmer agreed to stop selling cattle to private individuals. Overall 37 cases from 6 states were identified in this outbreak (Iowa-1, Georgia-2, Illinois-2, Minnesota-12, and Wisconsin-19). Human isolates obtained from case-patients in this outbreak were resistant to ampicillin, amoxicillin/clavulanate, cefoxitin, ceftriaxone, cephalothin, chloramphenicol, streptomycin, sulfisoxazole, and tetracycline and susceptible to ciprofloxacin, gentamicin, kanamycin, nalidixic acid, trimethroprim-sulfamethoxazole, and ertapenem.
