RENOUS, N.B. -- A union representing prison guards says its members should be told an inmate's medical history if they come into contact with their bodily fluids.

The Union of Canadian Correctional Officers says prisoners at the Atlantic Institution in New Brunswick have attacked guards with blood, urine and excrement in recent weeks.

The group says guards are not allowed to know if an inmate has a disease that could jeopardize their health.

The union is pushing for a blood samples act that would reveal an inmate's medical information following such an attack.

Doug White, the union's Atlantic regional president, says WorkSafeNB has rejected members' complaints.

He says guards are holding a demonstration at the institution and are calling on WorkSafeNB to reconsider its decision.
