Title Food Company in California Recalls Cheese Distributed Nationwide Due to Potential Listeria Contamination
Introduction LA Testing provides laboratory services to identify Listeria, E. coli, Salmonella, and other pathogens and contaminants to help prevent foodborne illnesses and costly product recalls.

Huntington Beach, CA, February 19, 2024

Last month, the U.S. Food and Drug Administration (FDA) posted information about the recall of hundreds of cases of Aged Cotija Mexican Grating Cheese by a cheese manufacturer in the San Joaquin Valley. The recall occurred after routine sampling by the Hawaii State Department of Health’s Food and Drug Branch revealed the product contained Listeria monocytogenes.

According to the recall notice, Listeria monocytogenes is an organism which can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems. It also warns that although healthy individuals may suffer only short-term symptoms such as high fever, severe headache, stiffness, nausea, abdominal pain and diarrhea, infection can cause miscarriage and stillbirths among pregnant women.

“The Centers for Disease Control and Prevention (CDC) estimates about 1,600 people get listeriosis, the name of the infection usually caused by eating food contaminated with Listeria monocytogenes, each year in the U.S.” said Michael Chapman, Laboratory Manager of LA Testing’s Huntington Beach facility. “Tragically, CDC also reports that about 260 die annually from the infection. At LA Testing, we are dedicated to helping companies and public health officials in their efforts to prevent contaminated foods from reaching the public. With multiple laboratories in California, our food scientists offer testing services to identify a wide range microbial pathogens and chemical contaminants. These services are instrumental for testing raw ingredients and finished products, as well as for evaluating harvesting equipment, production surfaces, and for confirming disinfection procedures at processing and manufacturing facilities.”
