People can now eat some fish caught in the Lower Hudson River for the first time in 50 years following a decline in harmful chemicals, according to the New York State Department of Health.

Officials say testing found lower levels of PCBs in certain species, including striped bass, leading to updated consumption advisories.

The advisory change applies only to the Lower Hudson River, which runs from the Rip Van Winkle Bridge in Catskill to the Battery in New York City.

Health officials say carp and smallmouth bass from the river are still not recommended for consumption.

Officials stress proper preparation is important before eating any fish from the river.

PCBs stay in the fatty parts of fish, so health officials recommend removing the skin and fat and cooking the fish so the fat drips off.

They say those steps can reduce PCB exposure by about half.

Consumption limits differ by group.

Sensitive populations, including pregnant women and children 15 and younger, are advised to limit consumption to one 8‑ounce meal per month.

The general population is advised they can eat up to four meals per month of approved fish species from the Lower Hudson River.

Officials urged anglers to continue checking local guidelines before eating what they catch.
