Dozens of people are sick after eating raw oysters in this state

More than 40 restaurants and retailers were advised to stop serving raw oysters linked to a new norovirus outbreak in
California. Although the exact source of the outbreak has not yet been identified, an estimated 44 people were reportedly
sickened after eating “Sweetwater” and “Atlantic” oysters distributed by Hog Island Oyster Company, Food Safety News
reports. Hog Island is one of the West Coast's most-respected oyster producers — the company owns popular oyster bars
in San Francisco's Ferry Building Marketplace and in Napa's Oxbow Public Market and supplies many other restaurants.
According to the Centers for Disease Control and Prevention, norovirus is a highly contagious virus spread through
contaminated foods and surfaces. Symptoms include vomiting, diarrhea, nausea and stomach pain. It’s a leading cause of
foodborne illness, but luckily it normally lasts just one to three days and typically doesn’t require any sort of medical
treatment.

The California Department of Public Health has shut down the company's oyster farming operations in Tomales Bay until
the investigation comes to a close. Hog Island locations will remain open and continue serving oysters and shellfish from
trusted growers based in Washington state, well outside the affected area .

“This is a temporary situation. Oysters will flush themselves of all viruses,” Hog Island said in a release. “We are working
with local, state and federal health departments to test and ensure the safety of our shellfish and we will resume harvesting
when the bay reopens.”

Oysters are highly susceptible to carrying norovirus, but the way they contract it is pretty gross. According to the
Washington State Department of Health, it “makes its way into the marine environment through untreated sewage (poop)
and vomit.” This happens by way of leaky septic systems, faulty waste and water treatment plants, and boaters and
beachgoers using the ocean as their toilet. Shellfish eat by filtering water through their bodies to get food floating in it, so
when norovirus particles are in the water, oysters end up sucking the virus right in.

To protect yourself from norovirus, the CDC recommends that you practice proper hand hygiene, handle and prepare food
safely, clean and disinfect surfaces and wash laundry thoroughly. To be most prepared, make sure you follow all of our tips
for avoiding food poisoning.
