Health authorities in Chile have taken action following the detection of Listeria contamination in dairy products. Initially, the Los Lagos regional health authority ordered the closure of a dairy processing and distribution plant in Frutillar. This decision followed an investigation linking a case of septicemia to Listeria and revealing structural, operational, and wastewater disposal deficiencies at the facility.

Subsequently, the Ministry of Health issued a food alert regarding the brand La Rotunda. Microbiological surveillance in the Valparaíso region identified Listeria monocytogenes in a specific batch of 300g sliced mantecoso cheese (batch T3180726, produced July 30, 2026). Authorities have initiated a sanitary summary process and are working to withdraw the affected product from the market, advising consumers to avoid the batch due to risks of serious conditions such as sepsis or meningitis.
