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.
