There are two types of trans fats found in foods: naturally-occurring and artificial trans fats. ​

Naturally-occurring trans fats can be found in small quantities in animal milk & meat fats, and sheep milk is no exception.​

Artificial trans fats (or trans fatty acids) are created in an industrial process that adds hydrogen to liquid vegetable oils to make them more solid. (e.g. margarine production).​

These artificially-created plant oil trans fats have been linked to cancer and some medical professional recommended avoiding these. The same is not true ​
for naturally-occurring trans fat found in milk.​
