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 O157: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.

Some people are more likely than others to get diseases from farm animals. A person's age and health status may affect his or her immune system, increasing the chances of getting sick. People who are more likely to get diseases from farm animals include infants, children younger than 5 years old, organ transplant patients, people with HIV/AIDS, and people who are being treated for cancer. Special advice is available for people who are at greater risk than others of getting diseases from animals. Click here for information on health risks associated with chicks.

Many organizations support the health benefits of animals. These groups provide information on how pets can help people be healthy.

Backyard Poultry

Keeping backyard poultry (chicks, chickens, ducks, ducklings, geese, and turkeys) is becoming more and more popular. People enjoy raising baby chicks and having fresh eggs from their established flocks. Though keeping chickens can be fun and educational, poultry owners should be aware that chickens and other birds used for meat and eggs can carry germs that make people sick.

Horses

Although horses can pass diseases to people, you are not likely to get sick from touching or owning them. However, when you do common chores with horses, such as cleaning stalls, grooming them, and picking out their feet, you are probably touching manure without knowing it. To protect yourself from getting sick, you should thoroughly wash your hands with running water and soap after contact with horses or their manure.
