@anxinapp: Four companies process roughly 85% of all the beef in the US today. JBS, Tyson, Cargill, and National Beef make up what's often called the "Big Four" of beef packing. In 1980, that same group handled about a third of the market. Today it's nearly all of it. Whatever brand ends up on the package at checkout, there's a good chance the beef itself passed through one of these four companies somewhere upstream. #foodsafety #foodorigin #knowyourfood #anxinapp
