Nine sick in Salmonella outbreak linked to pet guinea pigs
The Centers for Disease Control and Prevention has reported nine cases of Salmonella infection across eight states that are linked to pet guinea pigs. No deaths have been reported, but one person has been hospitalized.
According to an outbreak advisory
issued by the CDC, illnesses started on dates ranging from July 17, 2015, to Dec. 15, 2017. In December 2017 the CDC identified a cluster of three Salmonella
Enteritidis infections that whole genome sequencing
showed were closely related genetically.
“This outbreak is a reminder that pet rodents such as guinea pigs, regardless of where they are purchased or adopted, can carry Salmonella
bacteria even when they look healthy and clean,” according to the CDC advisory.
States involved in the outbreak include Colorado with two cases and one case each in Indiana, Iowa, Massachusetts, Michigan, New York, Virginia and Vermont. Public health officials interviewed seven people, and four of the seven people interviewed reported contact with a guinea pig or its habitat in the week before getting sick.
According to the CDC, the outbreak strain of Salmonella was identified in a sample collected from an ill person’s pet guinea pig in Vermont.
“This result provides more evidence that people in this outbreak got sick from contact with pet guinea pigs,” the CDC reported.
Anyone who has had contact with pet rodents such a guinea pigs and developed symptoms of Salmonella infection should seek medical attention and tell their doctors about the possible exposure so that the proper diagnostic tests can be performed.
Illness from Salmonella usually lasts four to seven days, and most people recover without treatment. However, in some people, the diarrhea may be so severe that the person needs to be hospitalized. Salmonella infections are more likely to be severe for children younger than 5 years, older adults and people with weakened immune systems, such as people with cancer, diabetes, and liver or kidney disease.
While contracting Salmonella, E. coli, Campylobacter and other bacteria from pets such as rodents is relatively easy, the following preventive measures recommended by public health officials are important and simple to follow, according to the CDC.

Pet rodents, including guinea pigs, are not recommended for families with children younger than 5 years, pregnant women, elderly adults, or people with weakened immune systems because these groups are at greater risk for serious illness.
