The outbreak of Listeriosis in the United States: At least three people died, and 22 were hospitalized due to contaminated salad.
The CDC warned that packaged foods from two different brands had sickened people in 13 states across the country.
Two listeriosis outbreaks linked to packaged salads have caused at least three deaths and led to the hospitalization of 22 people in the United States, the Centers for Disease Control and Prevention (CDC) warned on Thursday.
One of the outbreaks is related to products from the Fresh Express firm and has caused ten people to be hospitalized in 8 states, of which one died.
The other outbreak was linked to similar Dole products. In this case, 16 infected people have been registered in 13 states, with ten hospitalized and two deaths.
Listeriosis is an infection caused by eating food contaminated with Listeria monocytogenes. The CDC estimates that each year in the US, about 1,600 people become ill from this cause, 260 die.
The infection is more likely to affect pregnant women and their newborns, adults 65 and older, and people with weakened immune systems.
"Interviews with sick people and laboratory data show that packaged salads, Fresh Express brand, can be contaminated and make people sick," the agency noted.
Last Monday, the Fresh Express firm announced that it was recalling several salads, including the brands Fresh Express, Bowl & Basket, Giant Eagle, Little Salad Bar, Marketside, O Organics, Signature Farms, and Simply Nature, Weis Fresh from the Field and Wellsley Farms Organic.
The agency also warned that recent epidemiological and laboratory data indicate that packaged salads produced by Dole could also be contaminated.
On Wednesday, Dole recalled several of its prepared salads, including the Ahold, Dole, Kroger, Lidl, Little Salad Bar, Marketside, Naturally Better, Nature's Promise, and Simply Nature brands.
The CDC advised the public not to eat these salads and throw them away or return them to the market where they were purchased. He also recommended cleaning the refrigerators and surfaces that have been in contact with salads.
" Listeria can survive in the refrigerator and spreads easily to other foods and surfaces, " the CDC added.
