A salmonella outbreak linked to raw chicken products has plagued 92 people across the country, including nine in Massachusetts, according to a federal agency.
Health officials in several states are investigating the outbreak of multi-drug resistant salmonella infections, according to the US Centers for Disease Control and Prevention.
The outbreak has 21 hospitalized but no deaths have been reported, the agency said in a statement posted on its website on Wednesday.
Ill report that they "eat different types and brands of chicken products that they have bought in many different places," says the CDC.
The outbreak strain, according to the agency, was identified in samples of raw chicken feed, raw chicken products and live chickens.  A joint supplier of spoiled raw chicken or live chickens remains to be identified and federal officials said the outbreak strain is "resistant to multiple antibiotics".
"The outbreak strain of Salmonella Infantis is present in life chickens and in many types of raw chicken products, suggesting that it could be prevalent in the chicken industry," read the CDC statement.
On Monday, the onset of the disease had plagued people in 29 states, including nine in Massachusetts, two in Rhode Island and one in Connecticut, according to the CDC.
The disease started in January, according to the federal agency, and those who fell ill reached 105 by the age of less than one year.
Most people who are infected with salmonella develop diarrhea, fever and stomach cramps between them half day to three days after being exposed to the bacteria. The disease usually lasts between four days and one week, and most people recover without treatment, the CDC said.
