There’s a whole bunch of folks who like to protect the reputation of raw oysters, and we’ve heard from them before.

But it’s raw, and carries risks.

Based on blog reports, the San Francisco Oysterfest last month featured raw oysters, beer and a lot of barf.

"I am calling this event Salmonella-fest" wrote one yelper who, not surprisingly, gave the event just one star. Others wrote of suffering high fevers, shaking and even visiting the emergency room.

The Department of Public Health was on the case — and has determined the culprit was "campylobacter."

Eileen Shields, spokeswoman for the health department, said investigators couldn’t determine whether the bacteria was in the oysters, beer or any number of other food items served at the fest. After all, the food was all gone by the time word of food poisoning had gotten out.

But rest assured, oyster lovers. Shields said there’s no ongoing concern.

Maybe San Fran should follow how close the human shit comes to oyster beds. Or how often food service employees wash their hands.
