Have a bag of spinach salad in your refrigerator? Be sure to check its code number.

Dole Fresh Vegetables is voluntarily recalling some bagged spinach due to salmonella, according to the Food and Drug Administration.

Random tests by the Michigan Department of Agriculture and Rural development turned up positive for the bacteria.

Look on the bag for the code A27409B and A27409A. The UPC number is 7143000976. It has a sell-by date of October 15.

The spinach was sold in 13 states – Connecticut, Indiana, Kentucky, Maryland, Massachusetts, Michigan, Missouri, New Jersey, New York, Ohio, Pennsylvania, Tennessee and Wisconsin.

Dole is currently reaching out to stores to make sure they pull the product from grocery shelves.

If you do have a bag, the FDA said to throw it away.

Salmonella can cause severe stomach pains, nausea and diarrhea. For people with chronic illnesses, it can make them very sick. The elderly and small children are particularly susceptible to developing more severe symptoms.

Salmonella is a reoccurring problem in the United States. It’s estimated to cause a million illnesses in the country every year, sending 19,000 people to the hospital annually, according to the Centers for Disease Control and Prevention.

People who get sick tend to suffer for four to eight days. Most recover but, on average, 380 people in the U.S. die every year after suffering from salmonella infections.

Have questions about the recall? Dole set up a consumer response center which is open from 8 a.m. to 3 p.m. (PT) Monday through Friday. The number is 800-356-3111.
