An epidemic of E.coli infected dozens of people who ate bagged organic carrots, and one person died from the infection.

A total of 39 people were infected and 15 were hospitalized in 18 states after eating organic whole and baby carrots sold by Grimmway Farms, the federal Centers for Disease Control and Prevention announced Sunday.

Most infected people live in new YorkMinnesota and Washington, followed by California and Oregon, although infections have been reported in states across the country, according to the CDC.

There have been several outbreaks of E. coli in recent months. In October, more than 100 McDonald’s customers were sickened by an outbreak of E. coli in the United States linked to sliced ​​onions. In the United Kingdom, one person died in June in an outbreak of E. coli linked to lettuce which sickened at least 275 people. Organic nuts sickened consumers in 19 states with E. coli infections in April.

Despite the number of recent outbreaks, experts say the food supply is generally safe, although there hasn’t been much progress in combating infections caused by E. coli.

The recalled organic baby carrots have expiration dates ranging from September 11 to November 12, according to the U.S. Food and Drug Administration.

Symptoms of E. coli infection usually begin three to four days after eating the bacteria and include severe stomach cramps, often bloody diarrhea, and vomiting. People with severe symptoms of an E. coli infection should seek medical attention and tell the provider what they ate, the CDC said.

E. coli bacteria can cause serious and even fatal infections in young children, the elderly and people with weakened immune systems, according to the FDA.
