Campylobacteriosis is an infection caused by bacteria you can get from contaminated food and water. It causes diarrhea. When people worry about eating undercooked chicken, they usually focus on getting sick from salmonella bacteria. But another common type of bacteria called campylobacter can also make you ill if you eat poultry that isn’t fully cooked.
Causes
Touching poop: you can also get the bacteria from accidentally touching the waste (poop) of an infected animal. Cats and dogs can both carry Campylobacter. And some people have gotten infected after handling puppies for sale at a pet store. Always make sure you wash your hands after cleaning up after an infected pet or handling unfamiliar animals.
Age: Older people and the very young have the highest infection risk.
Immune system: people with weaker immune systems can more easily get infected. Weakened immune systems can come from cancer treatment, immunodeficient states, being a smoker or drinking a lot of alcohol.
Uncooked or undercooked food
Campylobacter infection starts after someone eats or drinks something with the bacteria. Uncooked or undercooked food can lead to an infection.
And finally, If your immune system is weakened by HIV or by medications to treat cancer, the bacteria can cause a serious infection in your bloodstream. See your doctor soon after diarrhea and other symptoms appear. Always see your medical provider for proper diagnosis and treatment.
