The role of Cryptosporidium parvum as a foodborne pathogen has not been well documented. Epidemiological features of this parasitic protozoon lead to the assumption that the incidence of cryptosporidiosis due to contaminated food is under-estimated. The high prevalence of C. parvum among dairy herds has increased the spread of oocysts in the farm environment, and their potential presence in raw milk and other raw foods. In October 1993, the first well-documented foodborne outbreak was reported in Maine, USA, and was caused by contaminated hand-pressed apple cider. Although various cases of cryptosporidiosis among humans have pointed to raw milk and other raw foods as possible sources of infection, a conclusive demonstration of foodborne cryptosporidiosis has rarely been established. The limited numbers of oocysts in the suspected samples and the lack of sensitive detection methods adapted for oocyst detection in food contribute to this under-reporting. This review paper discusses various aspects of Cryptosporidium spp. and cryptosporidiosis, including the routes of transmission, the control of oocysts in food, and the available detection methods. The polymerase chain reaction (PCR) combined with DNA probe hybridization is a promising detection method. Recent knowledge on the molecular biology of the parasite for the development of new PCR assays and their potential use in the detection of C. parvum in food are described.

    • ...As a source for many domestic outbreaks, the prevalence of C. parvum in cattle presents a continual threat to domestic water sources, raw beverages, and fresh produce (7, 9). Epidemiological studies have implicated contaminated raw milk and apple cider in many outbreaks of this gastrointestinal disease (2)...
    • ...Indirectly, fresh produce, such as leafy vegetables, has also been implicated as a result of washing with suspected contaminated water (9, 20)...

    • ...Cryptosporidiosis in humans is also associated with foreign travel, food, and direct contact with infected humans, farm animals, and wild animals [1, 7, 9]. It comprises 2 main genotypes [10]: genotype 1 (human type), which occurs virtually exclusively in infected humans, and genotype 2 (animal type), which occurs in farm animals as well as in humans...
