Listeria in Cheese: What Denver Residents Need to Know

Listeria Outbreaks Linked to Cheese in Colorado

The CDC has investigated several Listeria outbreaks associated with soft cheeses and imported dairy products that have affected Colorado residents, including Denver metro areas. These outbreaks typically involved raw-milk or unpasteurized cheeses produced at facilities without adequate sanitation controls. Listeria monocytogenes survives refrigeration and can multiply slowly, making contaminated cheese particularly dangerous. The FDA and FSIS conduct routine inspections of cheese manufacturing facilities, but detection often occurs only after illnesses are reported and traced back through epidemiological investigations.

Denver Health Department Response & Monitoring

Denver Public Health and Environment coordinates with the Colorado Department of Public Health and Environment (CDPHE) and the FDA to investigate suspected Listeria cases and recall contaminated products. When a recall is issued, the department distributes alerts through public channels and works with retailers to remove affected items from shelves. Local health officials maintain databases of implicated facilities and track distribution patterns to prevent further exposures. Residents can report suspected foodborne illness to the Denver Health Department hotline, which triggers investigation and reporting to state and federal agencies.

Consumer Safety Tips & Real-Time Alerts

Avoid unpasteurized and raw-milk cheeses, especially soft varieties like brie, camembert, feta, and queso fresco if you're pregnant, over 65, or immunocompromised. Always check product labels for "pasteurized" and store cheese at 40°F or below.
