yer-sin-ee-o-sis) is a relatively uncommon infection that people
can get by eating undercooked meat products (especially pork) or by drinking unpasteurized
milk or contaminated water.
More to Know
Yersiniosis is caused by bacteria that can infect the digestive
tracts of humans, cats, dogs, pigs, cattle, and goats. People can get yersiniosis
by eating or handling contaminated foods or drinking untreated water or unpasteurized
milk that contain the bacteria. Infants can sometimes get yersiniosis if a parent
or caretaker handles contaminated food and then doesn't clean up properly before handling
the baby's toys, bottles, or pacifiers.
Symptoms of yersiniosis usually appear 4–7 days after exposure to the bacteria
and can last up to 3 weeks. Symptoms include fever, stomach pain, nausea, vomiting,
and bloody diarrhea. Sometimes, older kids can also get pain in the lower right side
of the abdomen that may seem like appendicitis. Anyone can get yersiniosis, but it
is most common in young children.
Keep in Mind
Usually, people with yersiniosis recover within a few days without medical treatment.
In some cases, a doctor may prescribe antibiotic medications to treat the infection.
Most yersiniosis cases can be prevented by following rules for safe
food handling, drinking only treated water and pasteurized milk, and washing
hands frequently with soap and water.
