You don't get mad cow from eating red meat. You can however get it from eating part of the nervous system of INFECTED cows. It's almost unheard of in this country, unlike salmonella. If you ever had it, you would change your mind very quickly. I'm just amazed at the justifications that people use. I'm sure you wear seatbelts in you car even if you've never been in an accident right? You may not think you know anyone that this has happened to but it's a fact that a percentage of eggs are infected with salmonella. But there are lots of people who get food poisoning every year, thinking it is just a stomach bug. The ones you hear about are those that are hospitalized and die which does happen. The 1 in 6 number I posted about food poisoning was just reported out in the last few weeks by the CDC I think. I didn't make it up. I have never met anyone who hasn't had food poisoning at some point in their life. Even if it's just a mild case. I was sick for 8 days this past summer with it from a restaurant and believe me, it's not something I ever want to get again. You wouldn't either.
BTW, I love steak and don't see a risk of eating properly prepared beef so that argument is just weird.
