Campylobacter in Milk: Denver's Food Safety Response

Campylobacter Outbreaks and Denver's History

Campylobacter jejuni and Campylobacter coli are thermophilic bacteria commonly found in poultry, cattle, and other animals. Raw milk can become contaminated during collection if proper sanitation protocols aren't followed, and the bacteria survive in milk stored at refrigeration temperatures. The CDC and CDPHE have documented multiple Campylobacter outbreaks in Colorado linked to raw milk consumption and unpasteurized dairy products. Denver-area residents have been affected by these outbreaks, which typically cause severe diarrhea, fever, and abdominal cramps lasting 2–10 days. DPHE works with state and federal partners to investigate cases, identify sources, and issue public health warnings when necessary.

How Denver Health Departments Respond

The Denver Public Health and Environment coordinates outbreak investigations with the Colorado Department of Public Health and Environment, FDA, and CDC when multi-state incidents occur. DPHE conducts epidemiological investigations to trace contamination sources, collects environmental and product samples, and issues recalls or advisories through official channels. The Colorado Department of Agriculture enforces milk safety regulations and inspects dairy facilities for compliance with pasteurization and sanitation standards. Consumer complaints and physician reports of Campylobacter illness trigger rapid response protocols. Real-time monitoring platforms allow public health officials to detect clusters early and communicate risks to healthcare providers and the public quickly.

Consumer Safety Tips for Denver Residents

Avoid raw milk and unpasteurized dairy products, which carry higher Campylobacter risk than pasteurized alternatives. Ensure milk is labeled "pasteurized" or "ultra-pasteurized" and store it at 40°F or below. Wash hands thoroughly after handling raw poultry or animals, and keep raw meat separate from ready-to-eat foods to prevent cross-contamination. Cook poultry to an internal temperature of 165°F, as Campylobacter from animal sources is a common infection pathway. If you develop severe diarrhea, fever, or abdominal pain after consuming dairy products, seek medical care and report the illness to Denver Public Health (720-913-5000) so it can be investigated as a potential outbreak.
