Trichinosis is the parasite passed by raw pork.
No one actually knows whether all this stuff about 'all bacteria get killed in the gut' is true for dogs -- and home freezers will NOT kill bacteria or worm eggs. But there are studies that show far from killing bacteria in their stomachs, dogs simply excrete it so that collecting feces becomes essential with raw-fed feces potentially risky to children, the elderly or immune compromised people. A healthy dog probably has no problem passing certain bacteria through its system (just as most healthy people can tolerate certain levels while others can get quite ill).
I would just caution again: websites are NOT necessarily a reliable source of TRUE information on raw feeding giving both pros and cons, and most that I have read, from back when I tried a regular RMB diet, were to me obviously not just wrong but worryingly incorrect and unwilling to even consider for a nanosecond anything other than a rabidly pro-raw viewpoint. None for example look at any of the studies showing questionable hygiene in feeding raw and discount them in self-righteous terms. I note none ever mention the warnings from a leading wolf specialist who says it is inane to talk about a raw diet of raw bones being more natural and safe because it is what wild canids eat... because setting aside that they do know of captive wolves who have died from eating raw bones, and that wild canids like wolves are also eating skin, thick fur, feathers and meat that cushion the bones through the intestine, they also cannot tell how many wild wolves die from the same cause -- ruptured stomach/intestine/rectum -- that is definitely known to cause death in domestic dogs fed raw bones. In addition he reminds people, as do many vets, that the lifespan of a captive wolf fed meat (but not generally raw bones) is about 3 times the length of a wolf in the wild.
Please use common sense and a lot of skepticism when reading websites full of so-called 'truth' about any particular approach to feeding. Most of these places suppress studies and stories of the deaths animals have suffered when fed raw bones (a balanced raw meat diet -- and BALANCED is important here as meat alone is not 'balanced' -- to me is fine). But any vet will tell you how often they see fractured teeth and serious gastric problems and occasional deaths from feeding raw bones. You need to weigh up what you think the benefits are -- and whether those same benefits are not available from any range of chews -- and decide whether those outweigh the potential suffering and death of your dog (and eating kibble does NOT cause more choking deaths than eating raw bones -- yet another ridiculous story). Many raw feeders grind bone into meat rather than feed RMBs.
Deaths may be rare -- but no more rare than other things we carefully protect our dogs from. So to me an RMB diet needs careful consideration on what level of risk you feel comfortable with. Most vets I have spoken to have had serious cases of RMB fed dogs having emergencies or fatalities. Of course more occur from dogs being off lead, for example -- but there is a risk that should be considered.
I actually like raw meat diets though... think they can be of great benefit to dogs having problems with commercial diets ... and wish there were a commercially prepared one available here. I don't have freezer space to prepare large amounts and small amounts are too time consuming and messy to get right (for me!). PS I do on occasion give supervised raw bones -- but not regularly. I think regular feeding raises the risk element too high for my comfort zone, especially after last summer when I got first hand details of an RMB-fed rottie's horrible death from the vet caring for it.
