Public Health and Food Safety

New Mexico health officials say a newborn died of listeria in a case they believe was most likely caused by the mother drinking raw (unpasteurized) milk during pregnancy, and are urging residents to avoid unpasteurized dairy. The investigation could not pinpoint the precise exposure but, based on the timing of the infection and the mother’s reported raw‑milk consumption, concluded unpasteurized milk was the probable source. Listeria can cause miscarriage, stillbirth, preterm birth or fatal infections in newborns even when the mother has only mild symptoms. The warning comes as raw‑milk sales and advocacy have grown nationwide, helped by social‑media promotion and Health Secretary Robert F. Kennedy Jr.’s "Make America Healthy Again" push for less‑processed foods, raising concern among public‑health experts that more vulnerable people may be exposed to high‑risk products. Officials emphasize that pasteurization — briefly heating milk to high temperatures — dramatically reduces the risk not only of listeria but of other serious pathogens such as E. coli, salmonella and campylobacter.

The New Mexico Department of Health has issued a public warning against consuming raw (unpasteurized) dairy products after a newborn in the state died from a Listeria infection that officials say most likely stemmed from the mother drinking raw milk while pregnant. In a Tuesday statement, deputy state epidemiologist Dr. Chad Smelser urged pregnant women to consume only pasteurized dairy, noting that Listeria is the third‑leading cause of U.S. foodborne‑illness deaths and is especially dangerous for fetuses, newborns, young children, seniors and people with weakened immune systems. State agriculture secretary Jeff Witte emphasized that New Mexico’s dairies rely on pasteurization to deliver safe products and encouraged high‑risk consumers to avoid raw milk, even as raw dairy has gained popularity amid HHS Secretary Robert F. Kennedy Jr.’s Make America Healthy Again push that promotes full‑fat and less‑processed foods. The article situates the case in a broader pattern of raw‑milk outbreaks — including a 2023 E. coli and Campylobacter cluster tied to a Florida farm that sickened 21 people — and underscores that, despite a long‑standing FDA ban on interstate sales, state‑level legalization and online promotion have made unpasteurized milk far easier for U.S. consumers to obtain.
