When I did some research earlier on this subject, I came across this info:
http://www.wisc.edu/fri/briefs/crypto.htm
"However, oocysts are more resistant to cold and freezing temperatures (20). Oocysts suspended in water retained their infectivity after 168 hours storage at 5°C and at –10°C. At colder temperatures, infectivity was destroyed: at –15, –20, and –70°C, no infective cells remained after 168, 24, and 1 hour of storage, respectively."
-15°C is the same as 5°F and I was under the impression that most freezers were capable of going to 0°F (http://lancaster.unl.edu/food/ftmay04.htm#recommended).
Please let me know if I'm wrong about this. Right now I don't have any herp eaters, but if I do end up with one, I wouldn't want to proceed under the delusion that I'm killing everything by freezing.
Thanks,
Alice
