Campylobacter Outbreak Response in Baltimore

How Campylobacter Spreads in Baltimore

Campylobacter jejuni is the most common bacterial cause of foodborne illness in the United States and spreads primarily through undercooked poultry, unpasteurized milk, and contaminated water. In Baltimore, raw or undercooked chicken remains the leading source, as the bacteria colonizes poultry intestines without making the birds sick. Cross-contamination occurs when raw poultry juices contact ready-to-eat foods, kitchen surfaces, or utensils. Unpasteurized milk products sold through informal channels or farm stores pose additional risk, particularly to vulnerable populations. Person-to-person transmission is rare but possible, making proper kitchen hygiene critical during active outbreaks.

Baltimore City Health Department Outbreak Response

The Baltimore City Health Department (BCHD) coordinates outbreak investigations under authority of Maryland's Health-General Article and works with the Maryland Department of Health to detect and respond to Campylobacter clusters. When cases are reported by healthcare providers and laboratories, BCHD epidemiologists conduct interviews to identify common exposures, food sources, and at-risk populations. The department issues public health advisories through official channels and collaborates with food establishments and distributors to remove contaminated products. Investigation findings are shared with healthcare providers to improve clinical recognition and reporting. Real-time monitoring platforms like Panko Alerts aggregate BCHD notices, FDA recalls, and CDC outbreak announcements, enabling residents to receive alerts as soon as investigations are confirmed.

How Baltimore Residents Can Stay Informed and Protected

Cook all poultry to an internal temperature of 165°F (74°C), use separate cutting boards for raw meat and produce, and wash hands, utensils, and surfaces immediately after handling raw poultry. Avoid unpasteurized milk and dairy products, and only consume water from approved municipal sources or properly treated private wells.
