How does Norovirus get oysters? (It's quite gross)



Red oysters from Canada are linked to an outbreak of norovirus that is sick over 200 people, according to healthcare officers.

On Tuesday, May 1, the California Department of Public Health (CDPH) warned consumers to avoid eating oyster oysters from British Columbia involved in the outbreak. So far, the outbreak has sank about 100 people in California and 172 people in Canada, says CDPH.

But how does norovirus become in oysters?

Norovirus is a highly contagious virus that causes sudden vomiting and diarrhea. The virus can be spread from person to person, or by eating contaminated foods; and oysters and other seafood are common causes of outbreaks of norovirus, according to Centers for Disease Control and Prevention.

Exactly how norovirus makes its way to oysters is quite unappetizing: It may happen when sea shells are exposed to "untreated human sewage and spy," according to the Washington State Department of Health. Sewage can enter the ocean in several ways: for example, by leaky septic systems, incorrect sewage treatment plants, or even beachgoers using the ocean as a toilet.

Because the seafood filter seawater through their bodies for food, norovirus particles contained in the water can accumulate in shellfish, the Washington State Department of Health said. Although many types of seafood can transmit norovirus, eruptions are usually associated with oysters as they are usually eaten raw, the health department said.

In order to prevent norovirus diseases associated with eating seafood, CDPH recommends to cook seafood until the food reaches an internal temperature of at least 145 degrees Fahrenheit (63 degrees Celsius).
