This is old news, but since we missed it, we're guessing some of you may have too. 105 CMR 590.009(G) formerly "required certain chain restaurants to post calorie information next to the names of food items they sell. The regulations were to take effect on November 1, 2010, but were explicitly preempted by federal law (PL 111-148, s.4205) on March 23, 2010."
The requirement was removed from 105 CMR 590 on October 1, 2010 in Mass. Register #1166.
