Its typically just the Tuna that will be available at that grade.
On the pork side though, the common pork available is much safer than it was years ago - at least in terms of danger from Trichinosis. In fact, if you compare cookbooks & meat thermometers over the decades, you will see that the pork temperature has been decreased by over 40°F.
And for common supermarkets, I know Albertsons tends to have good quality meat, I still wouldn't eat the pork raw, maybe the beef - but I'd prefer other sources.
