JBS Tolleson is recalling 6,500,996 pounds of raw beef products because the meat may be contaminated with salmonella.

The U.S. Department of Agriculture’s Food Safety and Inspection Service (FSIS) identified the Arizona-based meat supplier as the probable source of products that caused people to become sick with salmonella. According to CNN, 57 people contracted salmonella illnesses in 16 states.

Possibly tainted beef sold across the U.S.

The meat was packaged between the end of the July and the beginning of September. The illnesses occurred during August 5 and September 6. The meat was sold throughout the country and in Texas at Sam’s Club, Walmart, Brookshire Brothers and Sprouts. There is a USDA inspection mark on the packages that reads, “EST. 267.”

Salmonella illnesses start quickly after consumption

Salmonella symptoms usually occur between 12 and 72 hours after eating contaminated food. The symptoms include diarrhea, fever and abdominal cramps. The sickness typically lasts four to seven days, but can require hospitalization. People with weakened immune systems, like the elderly and babies, are more susceptible.

Fourteen of those sickened by the outbreak were hospitalized, but no deaths have been reported.

All these beef products should be thrown out

The FSIS traced the outbreak through receipts and shopper cards of the affected consumers. The safety group is concerned some people may have frozen the beef for later consumption. The FSIS recommends all consumers throw away the meat or return it to the retailer.
