Even in the best run home composter, operated to achieve the highest temps in the largest volume of material, there _will_ be material which doesn't rise much above ambient air temperature. While it is a useful to aim for high temperature compost environments to kill many plant pathogens and weeds (and seeds), do not rely on a compost pile to kill human pathogens. ------- Nicely said, Richard. Also 100% accurate. Thank you for posting this. Catharine/Atlanta, zone 7b
