Urgent Health Alert: Listeria Contamination Prompts Recall of La Serenísima Cream Cheese
Table of Contents
A nationwide health alert has been issued following the detection of Listeria monocytogenes in a batch of Cremón double cream cheese produced by leading Argentinian brand, La Serenísima. Health officials are strongly advising consumers not to consume the affected product, even if it appears to have passed its expiration date.
The alert, jointly issued by the National Administration of Medicines, Food and Medical Technology (ANMAT) and the National Agri-Food Health and Quality Service (SENASA), centers on batch number 2703 of the 500-gram cream cheese. While the batch’s expiration date was November 9, 2025, and its production date was March 7, 2025, authorities emphasize the risk remains for those who may have stored the product, particularly if frozen.
Contamination Confirmed by National Laboratory
The presence of the dangerous bacteria was initially detected through routine health controls. Subsequent analysis by the National Reference Laboratory of the National Institute of Infectious Diseases “Dr. Carlos G. Malbrán” confirmed the findings in an official report dated December 9th, and formally notified last Tuesday. “The microbiological risk is significant, necessitating immediate action,” stated a senior official.
Production Halted, Market Withdrawal Ordered
In response to the contamination, SENASA has ordered immediate and stringent measures at the production plant of Mastellone Hnos. SA, located in Trenque Lauquen, Province of Buenos Aires. These actions include:
- Immediate suspension of all cheese production.
- Full intervention of all cheese batches currently at the facility.
- Comprehensive sampling for Listeria monocytogenes from all intervened batches and the production environment.
- Complete withdrawal of the affected lot (batch 2703) from the entire national market for subsequent destruction.
Additional controls have also been implemented to bolster preventative measures in the production processes.
Understanding the Risks of Listeriosis
Listeria monocytogenes is a particularly concerning pathogen due to its ability to survive and even thrive in refrigerated temperatures. The resulting illness, listeriosis, presents a unique challenge due to its extended incubation period. Symptoms can emerge anywhere from 12 hours to 70 days after infection, with an average onset of around three weeks, making it difficult to trace the source of the contamination.
Initial symptoms are often mild, including fever, general malaise, nausea, vomiting, diarrhea, and fatigue. However, listeriosis can escalate to severe, life-threatening infections such as meningitis or septicemia.
Vulnerable Populations at Highest Risk
Certain groups are particularly susceptible to severe complications from listeriosis. These include:
- Pregnant women: Infection can lead to transmission to the fetus, potentially causing premature birth, abortion, or congenital disabilities.
- Older adults: Individuals over 65 are at increased risk of severe illness.
- Newborns: Infants are highly vulnerable to the effects of listeriosis.
- Individuals with weakened immune systems: Those with conditions like HIV, cancer, or those undergoing immunosuppressive therapy are at significantly higher risk.
Immediate Recommendations for Consumers
Authorities are urging anyone possessing Cremón double cream cheese (lot 2703) to refrain from consumption, regardless of whether it has been fractionated or frozen. Consumers are advised to discard the product immediately. If symptoms develop, or if you have any concerns, prompt consultation with a medical professional is strongly recommended.
Preventing Listeriosis: Kitchen Hygiene is Key
To minimize the risk of listeriosis, health officials emphasize the importance of reinforcing basic kitchen hygiene practices:
- Personal Hygiene: Wash hands thoroughly with soap and water for at least 20 seconds before and after handling food.
- Utensil Cleaning: Sanitize all surfaces and kitchen utensils – including counters, knives, and cutting boards – that have come into contact with fresh food.
- Raw Vegetables: Wash all raw vegetables thoroughly before consumption.
Other foods frequently associated with Listeria outbreaks include cold cuts and sausages, dairy products made with unpasteurized milk, raw vegetables, and raw or smoked fish.
This situation underscores the critical importance of food safety protocols and vigilance in protecting public health.
