NSF International provides a variety of audits for farmers and growers of all sizes. Whether you’re looking for entry-level food safety guidance or more rigorous audits of your facilities, our experienced and knowledgeable auditors provide the feedback you need for regulatory compliance and retail acceptance.

Good Agricultural Practices

Implementing GAPs can help you meet retail and food buyers’ requirements and open more market opportunities. NSF companies offer a variety of GAP services to meet your sites’ and buyers’ specific needs, such as Tomato GAP, GLOBALG.A.P. and CanadaGAP. By utilizing GAP guidelines for safe farm management, growing and harvesting techniques and inputs, you take proactive steps to minimize your risk of microbial contamination.

United Fresh Produce Harmonized Audit

This single unified standard represents the harmonization of non-certification GAP audits in the U.S. and:

  • Focuses on food safety practices of pre-farm gate produce operations
  • Includes risk-based, science-based, attainable, auditable and verifiable requirements
  • Considers all potential microbiological, chemical and physical hazards, consistent with U.S. FDA regulatory guidance
  • Is scalable, applicable to fresh produce operations of various sizes
  • Accounts for regional and commodity-specific food safety needs
  • Accepts equivalent food safety practices


NSF provides audits to several GLOBALG.A.P. standards.

GLOBALG.A.P. Primary Farm Assurance

This entry-level standard for fruit and vegetable producers covers fundamental food safety for local and domestic markets and is:

  • Scalable, providing a stepwise improvement plan toward the full Integrated Farm Assurance (IFA) food safety standard
  • Recognized as one of the oldest farm certification programs on the market and accepted in over 100 countries by leading retailers
  • Market-driven, preferred by leading international retailers as a route for small suppliers to gain access to attractive markets

GLOBALG.A.P. Produce Safety Standard (PSS) Certification

This certification is ideal for producers supplying U.S. and Canadian retailers who are primarily concerned with the food safety of fresh produce. The certification:

  • Is scalable, serving as a stepping stone to IFA certification
  • Applies to fruits and vegetables for human consumption featured in the GLOBALG.A.P. product list

GLOBALG.A.P. Integrated Farm Assurance (IFA)

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:

  • A Good Agricultural Practice (GAP) standard with food safety requirements recognized by retailers and foodservice buyers worldwide
  • Implemented on more than 100,000 farms in more than 100 countries
  • Well-known, proven and practical to adopt
  • Recognized by the Global Food Safety Initiative (GFSI) as a primary production scheme


One of the most rigorous audits we offer, the PrimusGFS scheme is focused on food safety of fresh or minimally processed products from the agricultural sector that are designated for human consumption. Covering the scope of the supply chain, from pre- and post- farm gate production, PrimusGFS is a Global Food Safety Initiative (GFSI) benchmarked and fully recognized audit scheme covering HACCP, both GAP and GMP scopes, and food safety management systems.
