The Onondaga County Health Department says 60 people have become ill by Campylobacter because of raw clams served at an event at Hinerwadel’s Grove in North Syracuse.

The Health Department says so far, all of the illnesses have been linked to a clambake September 15th for the CNY Builders Exchange. Approximately 3,800 members attended that clambake.

The reported symptoms are related to Campylobacter, a bacterial infection that causes diarrhea, cramps, and fever. The incubation period for the infection is usually two to five days, but it can last as long as 10 days. Symptoms can last up to two weeks.  In rare instances Guillain-Barré Syndrome may develop.

The Health Department is asking that anyone who ate at the facility and became ill to call (315) 435-6607.

Notably, this is not the first time that Hinerwadel’s has been the source of a large Campylobacter outbreak. Exactly two years before the current outbreak, Hinerwadel’s clams caused a Campylobacter outbreak that sickened at least 236 people. In the 2008 outbreak, tests on Hinerwadel’s clams showed them to be contaminated by vibrio, another dangerous bacteria that lives in salt water, as well as Campylobacter.
