Welcome to the Food Borne Disease Site. The sources of the foodborne illness pathogens are ubiquitous. Food and food products will always be contaminated with low levels of pathogens. At low levels, pathogenic microorganisms cause no problems. At illness thresholds, however, they can make people ill and cause death.

Cryptosporidium parvum

Taxonomically Cryptosporidium parvum belongs to the phylum Apicomplexa, claas Sporozoasida, subclass Coccdiasina.

Cattle are infected with two species of C. parvum, which colonizes the small intestine of young claves and C. andersoni presents in the abomasum of cattle greater than 5 months of age.

The parasite was linked with diarrheal disease in variety of animal species and eventually in 1976, two humans cases were described, one in an immuno-competent child and the other in an immuno-suppressed adult.

C. parvum is zoonotic, apparently lacking host specificity among mammals. Opportunities for such infection increase with close human-to-human contact and during care of infected livestock, zoo animals and companion animals. Contracting C. parvum by drinking contaminated water was recognized from earlier reports human infections.
