Florida shoppers and food businesses are being told to check for Mon Sire Brie, a soft-ripened French cheese recalled because of possible Listeria monocytogenes contamination. The recall by Optimus Inc., doing business as Markys Caviar, appears in the FDA's enforcement report database and covers two lots of 1-kilogram cheeses distributed in Florida.
The U.S. action follows recalls of the same brand in Australia and New Zealand in early September. Those recalls involved different dates, and no public notice has linked them to a single confirmed source.
The practical concern falls on specific households. Listeria can cause serious illness in pregnant people, newborns, adults 65 and older, and people with weakened immune systems. Other people can be infected but rarely become seriously ill, and symptoms can appear weeks after eating contaminated food.
Lot Codes and Dates to Check
The Florida recall covers Mon Sire Brie in 1-kilogram packages with lot 00000ZRAA1, expiring Aug. 15, 2026, and lot 00000ZUAD2, expiring Aug. 18, 2026, according to a recall roundup from eFoodAlert that links to the FDA entry.
Both expiration dates have passed, which lowers the chance that the cheese is still for sale. It does not rule out leftovers in home refrigerators or freezers. Large wheels of brie are often cut into smaller wedges at cheese counters, so a shopper may have a wrapped portion without the original lot label.
The FDA classifies recalls by hazard level, with Class I reserved for situations with a reasonable probability of serious harm. A classification for this recall was not included in the materials MedicalDaily reviewed. The notices also did not report any illnesses linked to the Florida product or list specific retail stores.
A Brand Recalled Overseas
In Australia, Bottega 1995 recalled 1-kilogram Brie Mon Sire with a best-before date of Oct. 13, 2026, according to a Food Standards Australia New Zealand recall notice.
New Zealand's food safety regulator issued its own notice on Sept. 4. New Zealand's Ministry for Primary Industries said Sabato Limited recalled Mon Sire Brie, imported from France and sold in various weights, with a best-before date of Sept. 26, 2026. "Affected product should not be consumed," the ministry said, adding that there had been no reports of illness.
The sequence matters because imported cheese moves through international distribution networks, and Listeria can survive and multiply at refrigerator temperatures. Whether the recalls stem from one production problem remains unconfirmed, and no agency has announced an expansion to other U.S. states. The international pattern is a reason for Florida importers and delis to double-check inventory, not evidence of wider U.S. exposure.
Pregnant People and Older Adults Face the Greatest Risk
Listeria is especially harmful for certain groups, according to CDC's Listeria overview. In pregnancy, infection may cause only fever, fatigue, and muscle aches but can lead to miscarriage, stillbirth, premature delivery, or life-threatening infection in a newborn. Adults 65 and older and people with weakened immune systems, including those receiving chemotherapy or taking transplant medications, are more likely to develop invasive illness.
In people who are not pregnant, severe illness may cause headache, stiff neck, confusion, loss of balance, or convulsions in addition to fever and muscle aches. Symptoms of severe illness usually start within two weeks of eating contaminated food but can begin the same day or as late as 70 days later. Anyone at higher risk who ate the recalled cheese should tell a clinician even if they feel fine now.
People at higher risk who develop a fever after eating the cheese should not wait for symptoms to become severe. Clinicians can test for Listeria and treat invasive infection with antibiotics, and pregnant patients should tell their obstetric provider about the exposure. Florida's county health departments can help residents without a regular doctor find care.
Steps for Shoppers, Delis, and Restaurants
Anyone with Mon Sire Brie matching the recalled lots should not eat it. Throw it away or return it to the place of purchase. Listeria can survive freezing, so frozen portions should be discarded as well. If a wrapped wedge has no lot label and was bought in Florida this summer, it is reasonable to ask the store which lots it sold.
Cleaning matters as much as disposal, because Listeria can spread to other foods and surfaces in the refrigerator. Wash refrigerator shelves, drawers, containers, and cutting boards that touched the cheese with hot, soapy water.
Restaurants, caterers, and cheese counters in Florida should check invoices and cold storage for the two lots and clean slicers and surfaces used for the product. Pregnant people and others at higher risk can also ask about pasteurization and handling when buying cut soft cheeses.
The next step is whether the FDA publishes a recall classification or a fuller company announcement. MedicalDaily will update this report if new lots, states, or illnesses are identified, details that would change the risk for Florida households.
