Webinar: Compost and the FDA Produce Safety Rule

Date: 14 Aug 2023 | posted in: Composting | 0 Facebooktwitterredditmail

Are you a farmer who uses compost on their fields? A composter who sells to the farming community? A regulator who oversees rules relating to compost quality or on-farm compost use? This webinar will dive into FDA Produce Safety Rule Subpart F, which affects any farm applying stabilized compost to fields producing crops for human consumption in the United States.

Soil amendments are any material growers add to the soil to improve its physical or chemical properties and promote better crop growth, including compost and fertilizer. Subpart F focuses on biological soil amendments of animal origin (BSAAO), or amendments that contain animal-derived feedstocks, like manure or animal mortalities, and can include pre- and post-consumer waste like table scraps. Proper use of soil amendments is critical for managing soil fertility, improving soil quality, and often results in healthier and tastier crops. However, soil amendments, particularly BSAAOs, that are untreated or inadequately treated prior to application can contain harmful human pathogens that can cause foodborne illness in consumers. Though the current focus of Subpart F is on BSAAOs, composts made with post-consumer food wastes may be affected in the future.

In this webinar, Adriana Jimenez Lopez, Produce Safety Expert at the FDA, will provide an overview on the Food Safety Modernization Act Produce Safety Rule and draft guidance from the FDA to understand the current regulatory framework and requirements regarding soil amendments, with a focus on compost. This webinar will

  • Help growers understand risks and benefits of using BSAAOs and how to comply with the current requirements. This topic is especially relevant to growers of specialty crops that are typically eaten raw and produce covered by the Food Safety Modernization Act Produce Safety Rule (PSR).  
  • Help growers and compost producers understand farmers’ annual documentation requirements to demonstrate a valid composting process was used, and that the compost was handled, conveyed and stored in a manner and location to minimize the risk of re-contamination.  
  • Touch on how FDA’s Supbart F interfaces with USDA’s National Organic Program standards for time intervals between the application of untreated BSAAO on cropland. 

A recording will be provided for all registered attendees.
