Usually Campylobacter causes sporadic cases of illness, so having an outbreak is unusual and interesting for Campylobacter researchers. The article, from Food Safety News, states that the cause of the outbreak is still unknown.
“County health officials are not certain what food item might have caused the illnesses. They are still checking samples of cooked foods taken from the restaurant on June 8 and also continuing to investigate the reports of those sickened.”
Poultry, unpasteurized milk, and untreated water are the most common vehicle for Campylobacter transmission. Additionally, cheeses made from raw milk can be sources of infection. While the researchers are testing the cooked food, we also hope that the raw ingredients are being tested as well.
