One person died and 12 others were hospitalized because of a multistate outbreak of listeria linked to some packaged salads from Dole Foods, the Centers for Disease Control and Prevention said Friday.
Although an investigation into the recent listeria outbreak began in September, the source of the illnesses was not clear until January when tests linked it to packaged salad produced at the Springfield facility, CDC said on Friday.
Salads have been sold under the names Dole, Fresh Selections, Simple Truth, Marketside, The Little Salad Bar and President's Choice. They can be identified by the letter "A" at the beginning of the manufacturing code found on the package.
There is no evidence that salads made at other facilities are contaminated with the bacteria, the CDC said. Symptoms of an infection, which can take up to 70 days after exposure to develop, include stiff neck, headache, muscle soreness and flu-like symptoms that are sometimes preceded by nausea, diarrhea and other gastrointestinal symptoms.
The Ohio Department of Agriculture tested a Dole brand Field Greens packaged salad from a retailer in the state and found that it was contamined with Listeria.
According to the CDC, the ages of those infected range from 3 years old to 83 years old. The strain of listeria was "highly related genetically" to the listeria that had made people sick. These salads were sold under various brand names. It also can cause miscarriage, stillbirth, premature labor, and serious illness or death in newborn babies.
The Public Health Agency of Canada is presently investigating after seven people were hospitalized in a Listeria outbreak affecting five provinces. By state, the case count is as follows: Indiana (1), Massachusetts (1), Michigan (4), New Jersey (1), New York (4), and Pennsylvania (1).
