Trans fat does occur naturally in some meat and dairy products and not in trace amounts either. But the trans fat found in meat and dairy products is vaccenic acid and not elaidic acid. Elaidic acid is a trans fat that's converted from oleic acid, a monounsaturated fat, like olive oil. Elaidic acid is the main type of trans fat found in hydrogenated vegetable oils. Vaccenic acid, on the other hand, comes from polyunsaturated fats found in the cow's diet. The bacteria residing in compartments of the cow's stomach actually hydrogenate and convert the polyunsaturated fats into saturated and transfat.

And the good thing about vaccenic acid is that humans do a pretty good job converting it into CLA, the healthy fats found in butter.

And the study citing our effectivness at converting vaccenic acid to CLA can be found here

Turpeinen, A.M., et al., Bioconversion of vaccenic acid to conjugated linoleic acid in humans. Am J Clin Nutr, 2002. 76(3): p. 504-510.

So, long story short. The naturally occurring trans fats are not bad for you in normal doses and may even be beneficial.
