Stop & Shop on Tuesday issued a recall for two of its private brand mini muffins after the supplier said there was the potential the products were contaminated with listeria monocytogenes. The recall impacts select stores in Connecticut, Massachusetts, Rhode Island and New York - but not New York City stores, the grocery said. The impacted products are store-brand muffin mini blueberry streusel, sold in 12-ounce 12 packs, with product lot code GBF1C; and store brand G&G corn muffins, sold in 12-ounce 12 packs, with product lot code GBM1C. Customers are urged not to consume these products if they purchased them and to throw them away. A full refund will be issued with the receipt of the purchase at any nearby Stop & Shop or by calling customer service at 800-767-7772. The Centers for Disease Control and Prevention said the germ listeria monocytogenes causes a serious infection called listeriosis. The agency said the disease mostly affects pregnant women, newborns, older adults and people with weakened immune systems. About 1,600 people get listeriosis each year, the CDC said. It is usually a mild illness for pregnant women, but can cause severe disease for the fetus or a newborn baby, the CDC said. Some people with listeria infections, most commonly adults ages 65 and older and people with weakened immune systems, will develop severe infections of the bloodstream or brain. In terms of symptoms, the CDC said, pregnant women typically experience fever and other flu-like symptoms like fatigue and muscle aches. Infections during pregnancy can lead to miscarriage, stillbirth, premature delivery or a life-threatening infection of the newborn, the CDC said. Those who contract a listeria infection who are not pregnant can expect to experience headache, stiff neck, confusion, loss of balance and convolutions in additional to muscle aches and fever, the CDC said. People with listeriosis usually start to see symptoms between one to four weeks after eating food contaminated with listeria, with some reporting symptoms starting as late as 70 days later and some as early as the same day, according to the CDC.
