Massasauga rattlesnake bites Toronto Zoo worker

An employee at the Toronto Zoo was taken to hospital after she was bitten by a massasauga rattlesnake on Sunday morning.

The 45-year-old woman was in serious, but stable condition when she was transported, a Toronto EMS spokesperson told CBC News.

The zoo's website says that its massasauga rattlesnakes are housed in the Americas pavilion.

Prior to Sunday, a half-dozen massasauga rattlesnake bites had been reported in Ontario this summer, according to statistics from the Ministry of Natural Resources.
