Its baised on export and import. Sorry. I didnt read the atrtical posted. The 40 percent is what we keep, the rest is exported because its higher quality, and we import the lower quality beef. Imports and exports is not consumption. And while not reading the artical the imports were just from one country? And as you stated we import more then we export? So even if your correct we are short 1.8b lbs of beef per year? I may have misremembering the 40 percent. It may have included lamb and veal. That we dont produce anymore , or do at a very low percent. But AI says that beef is the same as veal and lamb imports? I will look at it further in the am.
What "40% of our own beef" are you talking about? Everything I see says we import around 15% of our beef and, per the article discussed above about Australia, it is mostly low-grade beef for hamburger. Data seems to be we import about 4.6B pounds (low-grade hamburger) and export about 2.8B pounds (high-grade steaks).
