WISCONSIN — Six people have fallen ill after consuming shelled peas from Wisconsin farmers markets and farm stands, according to the Wisconsin Department of Health Services.

Wisconsin DHS said the ongoing investigation has uncovered six salmonella cases linked to shelled peas produced by Green Barn Farm Market in Ripon, Wis. The loose peas have been sold at Green Barn Farm Market farm stands, as well as farmers markets in Ripon, Green Bay, Madison and Fond du Lac. The peas were also sold at Green Valley Acres Farm and Company’s farm stand in Neenah.

Wisconsin DHS also said three people have been hospitalized after consuming the peas, which are linked to salmonella infections.

Wisconsin DHS and the Department of Agriculture, Trade and Consumer Protection said they are working with local health departments to investigate the salmonella cases.

Wisconsin DHS said anyone who purchased loose peas from Green Barn Farm or Green Valley Acres Farm since July 1, 2022 should not eat them. Wisconsin DHS said the vegetable should be thrown away, even is it was frozen.

Anyone who consumed the peas and is experiencing symptoms of salmonellosis is advised to contact a doctor as soon as possible. Wisconsin DHS said to let the doctor know you may have been in contact with salmonella.

Salmonella infection symptoms include diarrhea, fever, abdominal pain and vomiting that persists for several days. Wisconsin DHS said it can cause bloodstream infections, but noted that is rare. Children, elderly and those with weakened immune systems are more likely to have more serious symptoms.

Salmonellosis is caused by salmonella bacteria, which are spread by eating or drinking contaminated food or water. It can also be spread by direct or indirect contact with faces from infected people or animals. Wisconsin DHS said most people can recover from salmonellosis on their own but some may need extra fluids to prevent dehydration.
