Cases of rabies have been confirmed in Potsdam and Lisbon, according to the St. Lawrence County Public Health Department.

Health department officials are warning people to be aware of strange, sickly or aggressive animals and to avoid contact with stray dogs, cats or wildlife.

Potsdam police picked up the first, a sickly and aggressive raccoon, just before Christmas. The raccoon was removed from Castle Drive, according to Potsdam Police, and has since tested positive for rabies.

A Lisbon skunk has also tested positive, according to the St. Lawrence County Public Health Department. The skunk was displaying abnormal behavior and approached some dogs.

Do not feed wildlife or trap wild animals for transport to a new location or to keep as pets, health department officials say.

The department also suggests that homeowners take steps to discourage animals from living on their property, such as covering potential entrances in attics or chimneys.

Pet owners should ensure that their pets’ vaccinations are up to date.

The department will host a rabies vaccination clinic Jan. 31 at the Cornell Cooperative Extension Farm, Route 68, Canton, from 1 to 4 p.m. Pets must have a current rabies certificate to receive a three-year vaccination certificate.

Although dogs and cats must be at least 3 months old to be vaccinated, pregnant pets may receive the vaccine.

Questions about rabies or possible exposures may be reported to the St. Lawrence County Public Health Department at 386-2325.
