Old Grouch, deplorable & reprehensible.
I do quite a bit of composting. One of the things I have come up with is a pretty good culture of thermophilic bacteria and molds that get organic material 'plumb hot' (up in the 160/170 degree Fahrenheit range) for making sure that e.coli and its kin get killed off. Given sufficient dry cellulose material, it makes a handy disposal for defunct critter carcasses. Have used it with dead horses and cattle.
