Food poisoning? It was likely a restaurant worker, says CDC

Approximately 20 million people fall ill every year due to norovirus, according to a new report from the Centers for Disease Control and Prevention, which says the food service industry could do much to decrease that number.

Restaurants and catering services are the most common sources for norovirus outbreaks from contaminated food, according to the report. "Infected food workers are frequently the source of these outbreaks, often by touching ready-to-eat foods served in restaurants with their bare hands," CDC experts wrote.

Norovirus is the most common cause of acute gastroenteritis - often called a stomach bug - in the United States, according to the CDC. Symptoms generally include stomach pain, nausea and diarrhea.

Norovirus particles spread whenever an infected person vomits or defecates. Because swallowing just 18 norovirus particles can sicken a new host, the virus spreads easily, especially when the infected patient is preparing food for a lot of people.

Norovirus is also hardy: It can live for up to two weeks on countertops, survive freezing temperatures, and is resistant to many disinfectants and hand sanitizer.
