Washington, May 2 The US Centers for Disease Control and Prevention (CDC) said that investigators have identified flour as the source of the recent Salmonella outbreak that has infected at least 13 people in 12 states.
Interviews with infected people and laboratory data showed that Gold Medal flour contaminated with Salmonella has made people sick, Xinhua news agency quoted the CDC as saying.
Three of the infected have been hospitalized without any deaths recorded yet.
But the actual number of sick people is likely to be higher than reported, and the outbreaks may not be limited to the states with known illnesses, it said.
"This is because some people recover without medical care and are not tested for Salmonella."
Last week, General Mills, the company producing Gold Medal flour, recalled two-, five- and 10-pound bags of bleached and unbleached all-purpose Gold Medal flour that have a "better if used by date" of March 27 and 28, 2024.
People infected with Salmonella usually experience diarrhoea, fever and stomach cramps.
Symptoms usually start six hours to six days after swallowing the bacteria, said the CDC.
Most people recover without treatment after four to seven days.
