If you have concerns or additional suggestions please contact the UVM Extension Produce Safety Team (firstname.lastname@example.org / (802) 257-7967) or the […]
By Chris Callahan, Hans Estrin, and Andy Chamberlin Summary Efficiency and food safety are integral parts of running a profitable and viable farm, producing high-quality produce, and retaining valuable employees. This integration should start with a vision in the planning stage of all postharvest projects.
I had the pleasure of facilitating a workshop at the 2019 NOFA-MA Summer Conference about Ventilation in Greenhouses and High Tunnels. It provided an opportunity to collect information from various sources, ground truth observations with growers, and to revisit some fundamentals. The big takeaway, for me, is that there are many, many ways to ventilate […]
Hygienic design intentionally creates or improves spaces and equipment so they can be cleaned and sanitized as appropriate. This post, associated PDF guide and checklist (PDF and Excel, instructions) are tools we developed to help apply hygienic and sanitary design practice on produce farms. We also collaborated on a video introduction to hygienic design with […]
The intentional, directional, and reliable flow of water is important to ensure agricultural water is “safe and of adequate sanitary quality”. This post provides information on the importance of backflow prevention and some common practices that help mitigate the risk of backflow. You can also view presentation slides and a recorded webinar on this topic […]
Last Fall we surveyed growers in the region about postharvest topics in preparation for a USDA NE SARE proposal. That proposal has been funded! Growers who responded assigned a high level of importance to aggregated postharvest knowledge (4.5/5.0, n=56) while indicating poor availability of the information (3.3/5.0, n=57). Several ideas for research topics were provided […]
We’ve received a number of inquiries about building germination chambers so we have decided to provide some consolidated resources and guidance. An important first step is to consider what the purpose of the chamber actually is. There are a number of horticultural practices that benefit from dedicated, environmentally controlled spaces. These include germination, starting, propagation/transplanting, […]
There are many options when it comes to constructing a walk-in cooler, cold room, or warm room for on-farm storage. The main goals for construction of any temperature and humidity controlled space are: Insulate the walls to provide for efficiency temperature control against a different outside temperature (which may be an warmer inside space) Seal […]
