Officials from Erie County issued a warning to select groups of people to not eat fish that has been caught in local waterways.

The New York State Department of Health has issued a recommendation that women under 50 years old and children under 15 years old should not eat any fish caught from the Buffalo River, Buffalo Harbor, Cayuga Creek, Delaware Park Lake/Hoyt Lake, the Erie Canal or Eighteenmile Creek.

Also, additional restrictions are placed on fish coming from Lake Erie and the Niagara River.

The advisories are based on the potential that those fish could be contaminated with PCBs, dioxins and other pollutants that can cause disease, hormonal imbalances, and immune system impairment.
