How Is This A New Regulation?!?!?!?

The US Department of Agriculture has proposed a new regulation that will require meat processors to wait for test results (regarding foodbourne pathogens) to come back before sending the meat. That's right as of right now, meat processors can allow meat to come to your local grocery store without knowing whether the meat is carrying any pathogens. While the USDA claims that most big processors do wait for the test results, it also claims that the lack of meats that waited for test results was responsible for about 44 class 1 recalls in a two year span. This new proposal would specifically target E coli, Listeria and Salmonella. While I am by no means saying this is a bad proposal, I am just simply shocked that it took so long for this to be proposed...
