No one got sick. The state issued no consumer advisory. A well-known California oyster farm still pulled almost a month of its own harvest.
Hog Island Oyster Co. shared that a hotel septic leak reached a creek feeding Tomales Bay. The state closed the bay to shellfish harvesting as a precaution. The leak was about 15 miles from the farm.
This is what raw-oyster safety looks like when the system works:
1. The state closes first, before anyone gets sick. Certified growing areas have a management plan ready, and oysters filter the water they live in, so a water problem becomes an oyster problem.
2. Every oyster is traceable. Harvest tags record where and when each lot was harvested, so a withdrawal can target exact dates instead of everything.
3. Oysters are cleaned before they leave. Harvested oysters sit in filtered, UV-sterilized seawater for at least 24 hours.
4. The farm went beyond what was required. This isn't a recall. It's a voluntary withdrawal, made before there was any evidence of a problem.
Raw oysters aren't safe because of lemon or hot sauce. They're safe because of systems like this. It's always fair to ask where your oysters came from and when they were harvested.

We want to share that Tomales Bay is under a precautionary, temporary state closure to shellfish harvesting following a septic leak at a hotel near Olema. No illnesses have been reported to the California Department of Public Health (CDPH), the county, or any growers in Tomales Bay, and the state has not issued a consumer advisory.
The closure is the state’s management plan working as designed. The leak discharged into Olema Creek, a tributary that feeds into the southern end of the bay, was 15 miles from our farm in Marshall. We don’t believe it poses a food safety concern. Even so, we’ve decided to take extra steps by voluntarily withdrawing all shellfish harvested from our Tomales Bay growing areas between September 14 and October 12, 2026. We’ve asked our restaurants and wholesale partners to pull any product they may still have from those dates. Please note, this is not a recall. It’s a precaution, taken out of an abundance of caution.
The health and safety of our customers is our top priority, which is why we’ve chosen to take these additional safety measures. We follow strict food safety practices regularly: every oyster is tagged and tracked from harvest to plate, all harvested oysters are held in tanks with filtered, UV-sterilized seawater for a minimum of 24 hours, and we work with state regulators who monitor water quality across the bay. When the state’s management plan calls for a closure, we follow it, and we’re working with CDPH to keep everyone safe.
In the meantime, our Humboldt Bay farm remains fully operational. Highwaters and Kumamotos from Humboldt will stay on our menus, alongside oysters from partner farms in other certified growing areas.
We’ll keep working closely with CDPH on testing and will only resume harvesting once we’ve been cleared to do so.
Thank you for your continued support.
