This globally recognized food safety standard covers agricultural businesses such as fresh produce, field crops, livestock production, plant propagation and compound feed manufacture. It improves farm management practices and compliance with legislation in the key areas of food safety, protection of the environment, worker health and safety, and animal welfare. It is also:

  • Implemented on more than 100,000 farms in more than 100 countries
  • Well-known, proven and practical to adopt
