Officials from the OSPCA have appeared on CP24's Animal House Calls and say that not all of the animals will be euthanized at the Newmarket shelter.

Board chair Rob Godfrey says they have so far identified 20 animals that can be saved and they will continue to assess the animals on a case by case basis.

On Monday, it was revealed that all of the 350 animals at the shelter would be euthanized due to an outbreak of ringworm.

Six shelter workers plus the 350 cats and dogs are infected with ringworm. Ringworm is a highly contagious fungal infection.

Shelter officials believe human error is responsible for the spread of the infection and confirmed on Tuesday that the euthanizing of all the animals had begun.

The OSPCA say many animals will still be put down, because their ability to survive is limited, at best.

Officials are only in the early stages of going "case by case" to see if any others can be saved.

Meanwhile, the person, who was let go at the center amid the outbreak, will not be facing criminal charges, Godfrey says. However, the OSPCA will conduct an investigation.
