Distributed by the New Jersey–based Lakeside Refrigerated Services, the products under investigation include ground beef patties and loose ground beef sold at retailers, including Walmart and Winn-Dixie, under brand names such as Thomas Farms, Naturally Better, Nature’s Reserve, and Marketside Butcher. Several of the items are labeled “grass-fed” or “Wagyu.” All the meats subject to recall bear establishment number “EST. 46841” inside the USDA mark of inspection. The complete list of products and product codes (PDF) for the beef items that are subject to recall, as well as the labels for the ground beef products (PDF) are on the USDA’s website. Because the products were made between February 1 and April 8, 2022, health authorities are worried that some of the ground beef may already be in consumers’ refrigerators or freezers. These items should not be eaten. They should be disposed of immediately or returned to the place of purchase. Although there have been no confirmed reports of illness or adverse reactions, the type of bacteria (Escherichia coli O103) detected can cause consumers to become seriously sick with diarrhea (often bloody) and vomiting. Symptoms may appear two to eight days after ingesting the organism. Some infections can lead to life-threatening conditions, such as a type of kidney failure called hemolytic uremic syndrome (HUS), which is most common in children under 5 years old, older adults, and persons with weakened immune systems. Severe illness may cause high blood pressure, chronic kidney disease, and neurologic problems. Many infected with E. coli show no symptoms or infections resolve without medical treatment within five to seven days. In general, recommended treatment involves intensive rehydration and other supportive care. If experiencing any symptoms, individuals are urged to contact a medical care provider. Infection is usually diagnosed by testing of a stool sample.
