Since it is August 20th already, I doubt anything is going to pass this year, let alone require any action this year.
The Federal Register publication of the revised rules came out last year. The comment period for that has been over for a long time. There is nothing more that the FDA needs to do except publish the final rule into the Federal Register and instructing the CFR to be modified. That would take effect immediately since there has been ample opportunities for public comment. Right now, the FDA is working on the support programs for the FSVP which is due to go into effect in October. So they are pretty much done with the Human Food portion of FSMA. The entire FSMA law is a phased implementation, everything is not going into effect at the same time.
Because they were sued by the Center for Food Safety to implement FSMA, and because they entered into a consent decree with the court, it would be difficult to change the Human Food implementation date significantly, because then they could be pulled back into court for contempt. There is nothing that the Judicial Branch of the government likes more than to make the other branches squirm. And the Judicial Branch has the final say in everything.
I believe that FSMA will probably be delayed by a short time, maybe mid September. But they may surprise me. The FDA cannot hire new people until October 1, if they get their budget. And they don't do most of the inspecting themselves, the states do it under contract to the FDA. But if all the sites gets visited before August 31, then they have until the end of the year to visit again.
