Salmonellosis
Salmonella
Salmonellosis is an illness caused by Salmonella bacteria. Salmonella live in the intestines of humans and animals; people get sick with Salmonellosis after swallowing the bacteria when they eat or drink contaminated food or beverages. They can also get sick after touching animals or their environment, or after handling pet food, pet treats, and other items contaminated with the bacteria without washing their hands.
Both animals and people can be carriers of salmonellosis. This means they are infected with Salmonella and can spread the illness to others without showing signs of sickness.

North Bay Parry Sound District Health Unit
Report to the Health Unit within one business day by fax (705-482-0670) or phone at 705-474-1400 or toll free at 1-800-563-2808, ext. 5229 if salmonellosis is suspected or confirmed as per Ontario Regulation 135/18 and amendments under the Health Protection and Promotion Act, R.S.O., c.H.7.
Should one go to childcare, school, or work if they have salmonellosis?
Exclude symptomatic food handlers, childcare workers and attendees, and anyone caring for high-risk individuals (e.g., elderly or those with a weakened immune system) until symptom free for 24 hours or symptom free for 48 hours after discontinuing use of anti-diarrheal medication. This is to ensure diarrhea does not return after the anti-diarrheal medication has been stopped. If antibiotics are used, the person should be excluded until symptom free for 24 hours. If a relapse occurs, exclude again, and seek medical attention as needed.
Follow the direction of your healthcare provider, public health case manager, or occupational health at your workplace.
