McDonald's, the largest fast-food chain in Hong Kong, has decided to switch to a trans-fats-free cooking oil, in line with its American parent.
No details were given on when the replacement would take place or what alternative would be used as a McDonald's spokeswoman in the city said it was still investigating ways to eliminate trans-fats from its outlets.
Krispy Kreme earlier said its Hong Kong outlets would work to develop a zero trans-fats doughnut, but it too gave no details.
The local McDonald's plan was disclosed after it was announced that all 13,700 McDonald's outlets in the US would switch to a canola-based blend after trans-fats were outlawed in restaurants in New York City.
That law will take effect in July but it was not known when the switch would be made across the rest of the country.
KFC in Hong Kong said its cooking oil did not contain trans-fats.
Trans-fats, which have been linked to heart disease, are formed when hydrogen is added to vegetable oils in a process called partial hydrogenation. They are present in margarine and some shortenings and frying oils.
