When was the last time there was a large scale die-off of US citizens from food products? Almost all the food poisoning that occurs is from improperly prepared foods, not the foods themselves. "Organic" may sound great, but it really means the crop was fertilized by animal waste (manure) and not other types of fertilizer. In many countries, you can get Organic vegetables fertilized with good old human waste, Yummy. Horse meat wouldn't be dangerous, what is appalling to most people is the though of eating good ole Trigger. But to keep the slaughterhouses from becoming a reality, it is better to allege safety issues as opposed to arguing you should only eat meat from unpopular animals.
