pathogen-free
Without infectious agents
Pathogen-free describes an environment, organism, or substance that contains no disease-causing agents such as bacteria, viruses, or parasites.
The term appears most often in scientific and medical contexts, particularly in laboratory animal research where specific pathogen-free mice are bred and raised in controlled conditions to ensure reliable experimental results.
Food processing and pharmaceutical manufacturing also aim for pathogen-free products to protect consumer health.
