The Centers for Disease Control and Prevention (CDC), along with state officials and the US Food and Drug Administration, has launched an investigation into cases of Shiga toxin-producing E.coli O103 and O121 reported.
According to the CDC, 21 people infected with the outbreak strains have been reported from seven different US states, with eight people hospitalized. So far, no deaths or cases of hemolytic uremic syndrome, a type of kidney failure, have been reported. The states with reported cases are Connecticut, Florida, Michigan, Missouri, New Jersey, New York and Pennsylvania.
CDC interviews with those affected and records collected from restaurants indicate that the outbreak can be traced back to ground bison produced by Northfork Bison Distributions, Inc.
Based in Saint-Leonard, Quebec, Canada, Northfork Bison Distributions recalled ground bison produced between February 22 2019, and April 30 2019. It is believed that the recalled ground bison was sold to distributors as ground bison and bison patties, referred to as Bison Burgers and/or Buffalo Burgers. Recalled ground bison was also sold to retailers in 4-ounce burger patties.
People get sick from Shiga toxin-producing E. coli an average of three to four days after swallowing the germ. Most people get diarrhoea, severe stomach cramps, and vomiting. In most cases, people recover within a week, but some illnesses can last longer and be more severe.
