The feed ban was designed to eventually eradicate the disease, but federal veterinarians say the potential for rare random cases to develop will remain.

该禁止令的目的是最终根除疯牛病，但是联邦素食协会的人说个别案例还会发生。

The cow involved in the latest case never entered the human food or animal feed chain. It was the fourth case to be discovered in Canada, and came more than a year after the last one.
