Making Mealtime Meaningful: Discover how we're giving back with the 12T Cares program →

While we would normally encourage you to get in as many green veggies as you can, right now we’d advise you to look into tossing them out instead. Mann Packing, a major produce supplier out of California, has issued a voluntary recall of their products due to a positive test result for listeria. The recall is widespread and affects packaged products sold in stores such as Walmart, Whole Foods, Meijer, and Trader Joe’s throughout the U.S. and Canada.

To date, no illnesses have been linked to the products in question but it’s still important to be cautious. The recall includes fresh packaged produce such as bags of broccoli, cauliflower, Brussels sprouts, salad kits, slaw, “nourish bowls,” and veggie trays with “best if used by” dates from October 11th through October 20th. One of Mann’s products received a positive result for listeria after a random sampling was tested by the Canadian Food Inspection Agency. Gina Nucci, the marketing director for Mann, encourages any customers who purchased the affected product to return it to the store where it was purchased.

A full list of recalled products can be found on the Food and Drug Administration website or in the Mann’s press release.

Listeria affects over 1500 people per year, and kills over 250 people annually, according to the US Centers for Disease Control and Prevention. While the listeria bacteria usually only causes fever, headache, stiffness, nausea, abdominal pain, and diarrhea, it can be very dangerous for children, the elderly, or those with weakened immune systems. It is also particularly dangerous for pregnant women, who are 10 times more likely to become infected. It can cause stillbirths or miscarriages and can also be passed on to the developing fetus.

People who have purchased recalled products are urged to discard them or return them to the place of purchase for a full refund. Those with questions can reach Mann Packing at their 24-hour consumer line, 888-470-2681, or visit veggiesmadeeasy.com/products.
