Growers Express Farms and Trader Joes is recalling many different varieties of fresh vegetable products for possible listeria contamination.

Butternut squash, cauliflower, zucchini and select veggie bowls are included in the voluntary recall and were sold under the Green Giant Fresh, Trader Joe's and the Signature Farms brands, according to a recall notice posted on the Food and Drug Administration website Monday.

The products came from a Growers Express production facility in Biddeford, Maine.

According to the notice, one sample tested positive for Listeria by the Massachusetts Department of Health and there have been no reported illnesses.

Most of the products are labeled with a “Best if Used By” date for June 26 through June 29, the notice said. No Green Giant canned or frozen vegetables are affected.

“The safety of our consumers is our first priority,” Tom Byrne, president of Growers Express, said in a company statement. “We are deep sanitizing the entire facility and our line equipment, as well as conducting continued testing on top of our usual battery of sanitation and quality and safety tests before resuming production.”

Listeriosis is a serious infection caused by the bacterium Listeria monocytogenes, according to the Center for Disease Control and Prevention. Symptoms can include fever, diarrhea, stiff neck, confusion and muscle aches. People usually report symptoms one to four weeks after infection.

Listeria can also cause miscarriages and stillbirths among pregnant women.
