MASARDIS, Maine — A fox that bit a dog has tested positive for rabies in Aroostook County and is the farthest north in Maine that the disease has been detected.

The Department of Inland Fisheries & Wildlife reported Monday that the incident occurred Friday in Masardis, about 10 miles south of Ashland. The dog was up to date on its rabies shots and there was no human exposure.

The case marked the second instance of a raccoon variant of rabies being reported in Aroostook County in 2009. Maine reported 71 cases of rabies in 2008 and 20 cases so far this year, with most of the incidents in southern and central parts of the state.
