Avoiding Contamination from Manure
To help avoid potential hazards of contamination by human pathogens such as as E. Coli O157:H7, Salmonella, and Cryptosporidum, make sure that all manure has been aged before application to your garden. Harmful bacteria can persist for up to six months in manure or in the soil and on plants treated with fresh manure, especially during cooler months. At least 180 days should be elapsed from the time of exposure before the planned crop is harvested. For example, a crop requiring 90 days from planting to harvest should not be planted until at least three months (90 days) have elapsed from the application of manure. Sometimes delaying planting or growing a longer season or lower risk crop (one that is cooked before eating) can help ensure food safety.
Avoiding Contamination from Flood Waters
Flood waters can sometimes carry harmful pathogens from feedlots or other sources of contamination, even as far as 10 miles away. If your garden has been flooded, follow the guidelines for manure above.
