So far, no meat products in the city have been found to contain clenbuterol, said Liu Yaqing, deputy head of Beijing's municipal agriculture bureau.
By Thursday, meat products from Jiyuan Shuanghui had been taken off the shelves in many major supermarkets after they received suspension notices in cities including Beijing, Shanghai and Guangzhou.
In a branch of Ito Yokado, a Japanese-invested supermarket chain, products made by other companies affiliated to Shuanghui had also been moved to the side.
"No one came to purchase this morning and sales have fallen sharply during the past few days," said an unnamed employee.
Some customers said they no longer consider the meat producer a safe bet.
"I will never buy any of their products again, even if they have been tested and passed fit," said a female customer surnamed Ge.
