The Centers of Disease Control and Prevention (CDC) warns that we are dealing with another serious outbreak of salmonella typhimurium—an infection caused by bacteria found in the intestinal tracts of humans and animals. Currently, this outbreak has affected more than 380 people, ages 1 to 103, in 42 states.

No deaths have been reported, but nearly 67 people have been hospitalized, according to the CDC, which has not announced which states are experiencing the outbreak or found the source of the outbreak. “We are reminding people that it is often difficult to trace the source or sources of salmonella outbreaks,” said CDC spokesperson Lola Russell.

Every year, the CDC receives reports of some 40,000 salmonella cases with about 400 deaths. In the past, salmonella has been traced to undercooked food, poultry, raw milk and cheese and even pet turtles. Common symptoms are diarrhea, fever and abdominal cramps, with deaths reported.
