Tanner Park Beach in Copiague and Amityville Beach in Amityville are closed to swimming, as water samples show higher than acceptable levels of bacteria, Suffolk County health officials said Monday.

James Tomarken, Suffolk’s health commissioner, said in a news release that swimming in bacteria-contaminated water can lead to gastrointestinal illness, and eye, ear, nose and throat infections.
