The CDC is investigating another salmonella outbreak. About 400 people in 42 states have gotten sick over the past three months, but investigators still don't know the source, Reuters reports. The usual culprits for this particular strain are cheese and undercooked poultry and eggs. Of those sickened, about 70 had to be hospitalized. Ohio has reported 51 cases, but no details were available on other hot spots.
"Because foods of animal origin may be contaminated with salmonella, people should not eat raw or undercooked eggs, poultry, or meat," said a CDC spokesman. People "also should not consume raw or unpasteurized milk or other dairy products. Produce should be thoroughly washed."
