    Jessiesmom- Thanks for the great info on cysts and bacteria and how cold the temperatures have to be to kill them by freezing. The only thing is, do regular freezers get that cold?

     
      I checked ours by putting a thermometer in it and it's 0 degrees, and our fridge is over 20 years old. I worry about the safety of raw food as much as you do which is why I checked to see if parasites could be killed by freezing the meat; I still worry some about bacteria. I won't feed raw eggs because of this;  [linkhttp://forum.dog.com/asp/tm.asp?m=133398&mpage=1&key=raw%2Ceggs%2Cbacteria𠤢]http://forum.dog.com/asp/tm.asp?m=133398&mpage=1&key=raw%2Ceggs%2Cbacteria𠤢[/link] .

    Thank you Jessiesmom- You've really helped me! I think I just have one more question; if freezing the food below a certain temp. kills bacteria and cysts, does it also kill the enzymes and other good things about raw food? [8|]

       You're welcome;[:D] I had that information bookmarked because I was concerned about feeding raw food to Jessie. Actually, you misread my earlier post; freezing kills parasites except for trichinosis which isn't a problem if you don't feed raw pork, but it does not kill bacteria according to the USDA website I linked, but most dogs don't have a problem with bacteria. If you look at that website under enzymes, it says that freezing slows them down, so I guess it doesn't kill them.

    Freezing doesn't damage most biological materials. It will kill living organisms because ice crystals form and burst the cells, but the proteins and so on aren't damaged. In the lab when we froze bacterial cultures or other materials we wanted to revive later, we'd add "antifreeze" to prevent the formation of ice crystals.
