Public Health Alert Issued
The CDC’s warning comes as part of an active foodborne illness investigation targeting requesón cheese products. According to the CDC’s food safety division, consumers should avoid purchasing or consuming the implicated cheese products until the investigation concludes.
Listeria monocytogenes can cause severe illness, particularly in vulnerable populations including pregnant women, adults aged 65 and older, and individuals with weakened immune systems. The Food and Drug Administration (FDA) reports that Listeria infections during pregnancy can result in miscarriage, stillbirth, premature delivery, or life-threatening infection of the newborn.
Investigation and Response
Health officials are working to identify the specific source of contamination and trace the distribution of affected products. The US Department of Agriculture is coordinating with state health departments to monitor the outbreak’s spread and implement appropriate control measures.
Consumers who have purchased requesón or similar soft ricotta cheese products are advised to check recall notices and dispose of any potentially contaminated items. Those experiencing symptoms of Listeria infection—including fever, muscle aches, nausea, and diarrhea—should seek immediate medical attention, particularly if they belong to high-risk groups.
