Aug. 6 (UPI) — Federal health officials are investigating a salmonella outbreak linked to jalapeños that has sickened 345 people in 27 states.

No deaths have been reported in the outbreak that began June 19 based on the earliest reported illness onset. The U.S. Food and Drug Administration said Wednesday in a statement that there have been 36 hospitalizations.

The last known illness onset date was July 20.

The outbreak of Salmonella Javiana infections has been linked to jalapeño peppers from Sinaloa, Mexico, and that were distributed by Coast Citrus Distributors to restaurants, including Mexican-style restaurants, as well as food service companies in the United States.

According to the FDA, of the 191 patients interviewed, 171 reported eating at a Mexican-style restaurant, including Chipotle Mexican Grill and QDOBA, between June 14 and July 14.

The CDC said the jalapeño peppers were primarily distribute to restaurants or wholesale and that the FDA was working to determine if any went to grocery stores.

The FDA said both Chipotle and QDOBA received product imported by Coast Citrus, with Chipotle switching its jalapeño supply for stores nationwide on July 20 and QDOBA on July 29.

QDOBA has also stopped serving jalapeños altogether.

“Given their actions to remove product from their stores, FDA does not consider there to be a current ongoing risk from these establishments to consumers in this outbreak,” the federal agency said.

Coast Citrus Distributors, at the recommendation of the FDA, has also agreed to recall the remaining implicated product, and is in the process of identifying and contacting affected customers, it added.

In a Wednesday statement, Chipotle said that after learning of the outbreak, it identified the Sinaloa jalapeños as a common ingredient from a common lot and “proactively removed them from the restaurants where they had been distributed, and replaced them with product from different growers.”

“The recalled jalapeño peppers are no longer in Chipotle restaurants and given these actions, the CDC and FDA have said they do not consider there to be a current ongoing risk with Chipotle restaurants in this outbreak.”

Salmonella bacteria are the leading cause of foodborne illness in the United States, according to the CDC, leading to about 1.35 million infections a year.

Eating contaminated food, drinking or coming into contact with contaminated water and touching animals, their feces or places they live are common ways people become infected, it said.

Those under 5 years of age and adults over 65 have increased chances of serious illness.

Symptoms include watery diarrhea that may contain blood or mucus, stomach cramps, headaches, nausea, vomiting and appetite loss. Symptoms usually begin between six hours and six days after infection and last up to seven days, according to the CDC.
