The AgriSafe Network is a organization representing health and safety professionals who strive to reduce health disparities found among the agricultural community. Here is their resources page on safe cleanup after flooding. Floodwater can be contaminated by pollutants, sewage, pesticides, and more. While health isn’t always the first concern after a flood, protecting health is a high priority. Resources include how to deal with wells, chemical and pesticide concerns, animal disposal, stress and mental health, and heat-related illness.
