Norovirus causes about one fourth of all food poisoning cases in Canada each year, according to a new study published in the May issue of the journal Foodborne Pathogens and Disease. About 4 million Canadians, one in every eight, are sickened by food poisoning each year, according to the study. Norovirus is also the leading cause of food poisoning in the U.S. where one in six people, or about 48 million, are stricken by foodborne illness each year.
The Canadian study looked at illnesses reported from a variety of sources including: the Canadian Notifiable Disease Surveillance System, the National Enteric Surveillance Program, enhanced national listeriosis surveillance, the provincial reportable disease surveillance system, national studies on gastrointestinal illness and C-EnterNet surveillance. Most of the illnesses reported, about 60 percent of them, were from unspecified agents.
