Salmonella outbreak possibly associated with reptiles and feeder rodents

July 22, 2022

PROVINCIAL— Alberta Health Services (AHS) is investigating an outbreak of Salmonella infections across the province, with links to reptiles and feeder rodents.

Twelve cases have been identified in four of five AHS Zones (North, Edmonton, Central, and Calgary). Investigation findings have identified exposure to both snakes and feeder rodents (used as reptile food) as a likely source of the outbreak. Investigation into the facilities carrying feeder rodents is still ongoing.

Anyone can become sick with a Salmonella infection, but children aged 5 years and under, older adults, pregnant women or people with weakened immune systems are at higher risk for contracting serious illness.

Most people who become ill from a Salmonella infection will recover fully after a few days. It is possible for some people to be infected with the bacteria and to not get sick or show any symptoms, but to still be able to spread the infection to others.

To prevent direct or indirect spread of Salmonella to yourself or others, follow these simple steps to help reduce your risk of becoming ill from contact with reptiles (including snakes), rodents and their environments:

Symptoms of a Salmonella infection, called salmonellosis, typically start 6 to 72 hours after exposure to Salmonella bacteria from an infected animal, person, or contaminated product.

Symptoms include:

These symptoms usually last for 4 to 7 days. In healthy people, salmonellosis often clears up without treatment. In some cases, severe illness and hospitalization may occur and in others, antibiotics may be required. People who are infected with Salmonella bacteria can be infectious from several days to several weeks. People who experience symptoms, or who have underlying medical conditions, should contact their health care provider if they suspect they have a Salmonella infection.

Even if snakes and rodents appear to be healthy, clean and show no signs of illness, they can still carry Salmonella bacteria. Having indirect contact by touching their environments can put you at risk for developing a Salmonella infection.
