I would suspect that, as with many parasites besides the hardcore Trichinella parasites in wild game (cougar jerky, yum!), freezing the meat for a period would likely kill them. The Merck Manual reports:
Experimental work demonstrated that infected pork could be made safe for consumption by cooking at 70°C for 15 min or by freezing at -4°C for 2 days or -20°C for 1 day.

Any uncooked meat I feed to the dogs is frozen at least 3 weeks before giving it to them. And no bear or cougar meat.
😉
Of course just meat isn't balanced. The BARF and raw diets are not just meat...it is meat, bones, organ meats, veggie mashes, all from various sources. Many people also do whole prey model diet.
*waits for Electrophile to get all up in this thread* 😉 I would but I'm sooo friggin busy right now...
You rang?
Regarding completeness, my snakes doesn't eat kibble and they can live 20-40+ years in captivity eating whole mice and rats. So yeah, basically, if you do a raw diet, you'll really to duplicate those prey items. People who claim to be feeding a whole prey model diet but just do chicken necks and quarters and some occcasional liver ain't cutting it. You have to do a veggie blend and/or green tripe, edible bones, and organ meats, just as WTF (haha) said.
Speaking of nutrition software, I ran a week's worth of a typical raw diet through the Zootrition software to turn it into a day's (added up all the stuff I'd feed in average week and divided each ingredient by 7) and it actually came out pretty well, even with really pretty minimal supplementing. The other thing I like about that program is that you can use whole prey items since it's for zoo animals as well as domestic species. One thing that is problematic about nutrition software is that some values for some nutrients for some foods have not really been evaluated, researched, or updated, or there was a small sample size. So there is going to be tremendous variation. I try to look stuff up here when I can:

Also, regarding human nutrition, if a company came out with a granola bar kind of thing that they GUARANTEED could cover your nutritional needs FOR THE REST OF YOUR LIFE (with a kid formula, lactating and pregnant woman formula, and senior formula, of course) because they fed it to 8 people for six months and did very minimal blood work and made sure the people didn't lose more than 15% of their body weight and only 2 died during the trial, would you seriously eat it? Thanks but no thanks! Besides the fact that I'm a foodie at heart, we don't know everything there is to know about human and animal nutrition. About every 5-10 years, there seems to be a paradigm shift in nutrition and I don't want to ever presume to know more than mother nature.
That being said, I don't really do much raw feeding currently for a number of reasons (mostly $$ since I'm the Natura student rep and free is much cheaper than $300-400 a month on 4 dogs), but I have done it successfully for about 4 years now. No perforations, good blood work, good radiographs, I'm not coming down with salmonella or E. coli every other day. I won't go out of my way to recommend it to people, but people are going to do it whether you tsk tsk them or not, so might as well do it correctly, I say.
