Hygienic and Sanitary Design for Produce Farms

Hygienic design intentionally creates or improves spaces and equipment so they can be cleaned and sanitized as appropriate.

This joint illustrates how intermittent welds lead to a gap, or sandwich joint that can lead to harborage. A continuous weld that is then ground smooth would lead to a seal and be easier to clean, sanitize, and dry completely.

This post, associated PDF guide and checklist (PDF and Excel) are tools we developed to help apply hygienic and sanitary design practice on produce farms. These tools cover the five key principles of hygienic design for produce farms:

  1. Visible and Reachable Surfaces
  2. Smooth and Cleanable Surfaces
  3. No Collection Points
  4. Compatible Materials
  5. Preventing Contamination

Mighty Clean and Comfortable (Video Series)

Lisa MacDougall has led Mighty Food Farm through start-up, relocation from rented land to owned land, and now through the construction of a brand-new 60 ft x 90 ft wash and pack shed. She’s done this all while producing a diverse mix of organic vegetables, tree fruit and berries on fourteen acres, now, in Shaftsbury.

We’ve already posted a write-up about this case study here, but we just released videos that go along with it! In the playlist below there is an intro video, followed by a video showing the washing process in the new space (2min), the use of a Grindstone Barrel Washer on carrots and beets (2min) as well as the full-length interview (11min) with Lisa about the project.
