Diseases from Farm Animals
Farm animals including cows, sheep, pigs, chickens and goats, can pass diseases to people.As you know, farm animals are not like house pets and do not have places to rest or eat that are away from where they pass manure. Therefore, you should thoroughly wash your hands with running water and soap after contact with them or after touching things such as fences, buckets, and straw bedding, that have been in contact with farm animals, adults should carefully watch children who are visiting farms and help them wash their hands well.
Different types of farm animals can carry different diseases. For example, cows and calves can carry the bacterium Escherichia coli O157:H7, often called E. coli (ee COH-lie). This germ can cause bloody diarrhea in people. In addition children can develop kidney failure due to E. coli 0157:H7 infection. Pigs can carry the bacterium Yersinia enterocolitica (yer-SIN-ee-ah en-TER-o-koh-LIH-tee-kuh), which causes the disease yersiniosis (yer-SIN-ee-OH-sis). Chickens can carry bacteria such as Salmonella, (sal –mon – Nell – ah) which causes the disease salmonellosis. Many of these germs are in farm animal manure.
