Really any uncooked meat can pose a risk to many animals. You shouldn't really have to worry about it as long as you cook your meat very well for consumption. There are only a few things that can survive high levels of heat and most of these diseases form during storage like botulism and clostridium.
I know I won't change anyone's opinion on this matter if they are already set in what they believe, but if you provide your pigs with adequate food, water, shelter, and a relatively stress free environment, you should never have an issue with cannibalism no matter what you feed. You'll always have anomalies, and perhaps feeding raw might present a slightly (and I refer to a VERY small) higher risk of turning pigs cannibalistic, but if you think about it, dogs that are fed a raw diet are really no more likely to go and antagonize a cow because it ate a roast for dinner than a dog fed dog food.
