I did have time to dig around just now, and found most of the answer to our question on the FAQ page:
In response to one of the FAQs re. ideal time and temperature required for destruction of weed-seed potential (at https://www.compostingcouncil.org/contact/faq.php ), this is the response. (NOTE: I've copied it over without any spelling correction or other edits, to preserve the integrity of the reference w/regard to copyright.)
"Research has shown that maintaining tempertures over 131 F for several weeks with multiple turnings during that time will eliminate almost all weeds (if you are handling feedstocks with human pathogen potential, like manure, post-consumer food scraps or biosolids, you are required to maintaing that temp for two weeks with 5 turnings duing that time). However, the only way to keep the compost weedfree is to cover the compost with a breathable fabric before it finished cooling off."
I didn't find any other public info about minimum periods of time for destruction of pathogens in animal manures. Given the other info I did see on their website, though, the USCC is anticipating feed-lot manures or other commercial sources, but this would include pigs as well as cattle, since both are subject to CAFO (concentrated animal-feeding operations) or "factory farming" in this country. The FAQ immediately previous to this one mentioned windrow technology, so the USCC standards are clearly aimed at large-scale, commercial compost generation.
It doesn't seem to have occurred to them that dedicated private citizens who truly want to reduce their own contributions to the waste stream might like to have access to health and safety information.
