Regionally, the highest rates of laboratory reports were recorded in the Northeast, at 10.6 cases per 100,000 population, and the Southwest, at 10.3 cases per 100,000. The Southwest reported the highest number of outbreaks, followed by the Northeast. Children aged 0–9 years accounted for the largest proportion of laboratory reports, at 26.2 percent, followed by adults aged 30–39 years, at 22.5 percent.

UKHSA recorded 29 Cryptosporidium outbreaks in 2025, comparable to the 32 outbreaks reported in 2024, although fewer outbreak-associated cases occurred in 2025. Farm settings remained the predominant setting for outbreaks, accounting for 18 (62.1 percent) of those reported. One small outbreak was linked to pasteurized milk sold at a farm vending machine.

Cryptosporidium and Food Safety

Although Cryptosporidium can be transmitted through routes other than food, the parasite remains important to food safety. Explained by Larry Keener CFS, PA in Food Safety Magazine, Cryptosporidium spp. have been identified among potentially foodborne parasites of importance that are not routinely controlled in food. Parasites can contaminate foods at multiple points in the supply chain, including through contaminated irrigation water and contact with animal or human excrement during cultivation, harvesting, and handling. Additionally, foodborne parasites present challenges for detection, diagnostics, traceback, and control. For Cryptosporidium and other parasites transmitted as fecal contaminants, validated detection methods, survival and infectivity assays, and consensus molecular typing protocols are needed to support quantitative risk assessments and effective control measures.
