Specific Pathogen Free Sheep

NEO SPF sheep and lambs are validated-free of over 30 disease-producing agents also known as “pathogens”.

What does Specific Pathogen Free mean exactly?

An animal or population of animals that is defined as being without a particular disease-producting agent is considered "specific pathogen free" for that agent. Agents of which a given animal or a group of animals is free should be named and the animal or population of animals should be under ongoing surveillance to demonstrate that the agent continues to be absent in the animal or population.

See the list of specific pathogens for which we routinely screen.

*Zoonotic agents are pathogens that are transmissible from animals to people and are indicated by an asterisk (*) on the list.
