Contra Costa Health Services (CCHS) has now identified two additional people who fell ill soon after eating food from a Thanksgiving charity event in Antioch.

All people who became ill developed symptoms within 24 hours of ingesting food served at the charity event and we don’t expect to see new cases.

These two newly discovered people didn’t seek medical attention and have recovered. There are now 19 total people known to have fallen ill—including three people who died—after eating food served at the Antioch American Legion auditorium, 403 West Sixth St., on Thanksgiving.

Anyone with leftover food from this event should not eat it and throw it away. Anyone who ate food from the Thanksgiving Day event and is now feeling sick should immediately contact their medical provider and also call CCHS at 925-313-6740.

Tests of biological samples from the reported cases came back negative for 21 foodborne diseases, including salmonella, E. coli and norovirus. CCHS is sending samples to the Centers for Disease Control & Prevention (CDC) to test for other agents that are common but testing is not locally available. Results from the CDC tests may not be available for months.
