US meat processor Tyson Foods has said that it has begun the process of removing trans fat ingredients from its fully-cooked retail and school foodservice products.

Tyson began implementing the changes this week with Tyson-brand breaded chicken products, such as nuggets and patties, and the company expects to phase in the remaining changes over the next three months.

Tyson said that although its chicken, beef and pork are naturally low in trans fat, the substance can be found in certain added ingredients, such as breading and cooking oils.

"We know today's consumers are more health- conscious than ever before, with increasing awareness of the nutritional composition of the food they eat. Our goal is to provide consumers with a wide array of food options, and the information to make choices that are appropriate to their own lifestyles," said chief marketing officer Bob Corscadden.
