Portland Foodborne Illness Outbreak Tracker

Common Pathogens in Portland Outbreaks

Salmonella remains the most frequently reported pathogen in Portland area outbreaks, often linked to poultry, eggs, and cross-contaminated produce. E. coli O157:H7 cases also occur regularly, primarily traced to ground beef and leafy greens. Listeria monocytogenes poses serious risk in ready-to-eat foods like deli meats and soft cheeses, particularly threatening pregnant women and immunocompromised individuals. Campylobacter contamination frequently appears in undercooked chicken and unpasteurized dairy. Norovirus spreads seasonally through institutional settings and foodservice operations across the Portland metro area.

How Multnomah County Health Investigates Outbreaks

When multiple cases of illness are reported, Multnomah County Health Department epidemiologists conduct case interviews to identify common exposures and foods consumed. They work with the Oregon Health Authority and CDC to confirm pathogens through laboratory testing and genetic fingerprinting (whole genome sequencing). Health inspectors conduct immediate facility investigations, reviewing food handling practices, temperature controls, and sanitation protocols. The agency issues public health alerts and, when necessary, recalls affected products in coordination with the FDA and FSIS. Investigation timelines typically span 2–4 weeks from initial case reporting to public notification.
