In a random test conducted by the Michigan Department of Agriculture & Rural Development, one sample tested positive for salmonella. That result prompted Dole to issue the voluntary recall on October 13. No illnesses have been reported.

Salmonella is a bacterium that can make you sick if you eat food contaminated with it, according to the Centers for Disease Control and Prevention (CDC). Symptoms include diarrhea, fever and abdominal cramps, which develop in 12 to 72 hours. The illness usually lasts four to seven days. Most people recover without treatment, the CDC says. Babies, senior citizens and people with weakened immune systems are most likely to get sick.
