Final Produce Safety Rule

  • FSMA Final Rule on Produce Safety

  • Produce Safety Alliance http://producesafetyalliance.cornell.edu/
    From the website:  The PSA is developing a nationwide curriculum to increase understanding of the principles of Good Agricultural Practices (GAPs) and to facilitate the implementation of food safety practices on fresh fruit and vegetable farms and in packinghouses.

Agricultural Water and Soil Amendment Framework Documents

The Western Center for Food Safety was asked by the U.S. Food and Drug Administration to facilitate the development of research protocols for scientific studies that evaluate the persistence of foodborne pathogens in the environment and on the edible portions of fresh produce following:

  • application of potentially contaminated untreated soil amendments of animal origin to land used to grow fresh produce or
  • application of potentially contaminated agricultural water applied to the edible portion of the crop

The Agricultural Water and Soil Amendment framework documents were developed by two committees through a series of webinars, e-mail communication and a workshop that was held in Davis, CA in October 2011. Additional academic, government and industry food safety experts reviewed the draft documents prior to submission to the Journal of Food Protection.

Agricultural Water

The Produce Safety Rule (PSR) requires growers to initially establish a Microbial Water Quality Profile (MWQP) for each untreated surface agricultural water source and conduct annual surveys for that water source in subsequent years. The water quality profile is based on the levels of generic E. coli in your agricultural water.

The initial MWQP must be established with a minimum of 20 water samples collected as close to harvest as possible over a period of at least 2 to a maximum of 4 years. Geometric mean (GM) and Statistical Threshold Value (STV) are calculated from these 20 samples (minimum). The GM and STV are your MWQP and should be compared to the microbial quality criteria provided in the Produce Safety Rule.

These tools were developed to make it easy to calculate the GM and STV and to determine if your water meets the standards for unrestricted application to produce before harvest. The tools were also designed to assist you with making food safety management decisions if your water does not meet the standards in the proposed rule.
