Another one bites the dust! Though, their fries have been pretty crappy for years, maybe they changed earlier in my area. I never eat there anymore:

McDonald’s french fries are now trans-fat-free in all its restaurants in the United States and Canada, the fast-food restaurant chain said Thursday.
McDonald’s has lagged other restaurant operators in switching over to a zero-trans-fat cooking oil out of worries it would compromise the taste of its trademark fries. It has been under increasing pressure from consumer advocates and some public officials to make the change.

Skinner said the company decided not to advertise the changes.

If I were them I wouldn’t advertise either, why advertise that your food has an annoying aftertaste.
