Manufacturers cannot add ANY transfats anymore. So the rounding
down thing is kinda defunct. Foods can still have transfats
naturally, such as meat, but those aren't required to be listed
As for the OP, you missed The Wagon by about a year. EVERYBODY in
the U.S. is on the TransFats bandwagon now since they're not
supposed to exist anymore.
There is still 5 grams of transfats per pound of 80% ground beef
(less in pork, lamb, and butter), but the jury hasn't quite
determined if they're as dangerous as the manufactured transfats.
