Poisonous plants are a major cause of economic loss to the livestock industry. Two poisonous plants common to Oregon are poison hemlock and Western water hemlock. Ingestion of either by humans or livestock typically results in death.
Mature cattle grazing in pastures with rapidly growing grass are sometimes afflicted with a disease called grass tetany. The cause is a lack of magnesium in the grass. Here's what to look for and how to treat it.
Hand-washing is important to prevent the spread of disease, but it's important that it's done properly. High Speed Hand Washing is designed for groups to wash hands thoroughly and quickly. Here's how to demonstrate.
Silage-making has been used to reduce the concentrations of toxins in a variety of crops. But in the case of poison hemlock, the opposite is true — making silage out of it actually increases one of its toxic alkaloids.
The intent of this add-on exercise is for PSA grower course trainees to think through various harvest and post-harvest scenarios and consider implications related to produce safety in the context of real production environments. Each group of trainees (4-6 per group) is given a set of the printed photos to work through. They are asked specific questions, and given 15-20 minutes to work in their groups. Following group discussions, trainers go through the slide deck and ask participants to share what they discussed in their groups about each scenario.
