McDonalds recalled its ‘Shrek’ drinking glasses this morning in a frenzy to prevent consumer sickness. The cups have been found to be made with cadmium, a chemical that may cause lung disease. The U.S. Consumer Product Safety Commission is working with the world’s biggest restaurant chain to recall the products.

The cups come in four variations, from the main characters of the DreamWorks movie: Shrek, Princess Fiona, Puss n’ Boots and Donkey. Cups were wrongly deemed safe by an independent laboratory.

Business Week reported:

No injuries have been reported, and McDonald’s is advising customers to stop using the 16-ounce glasses, which sold for about $2, according to the statement from the CPSC.

“McDonald’s determined in an abundance of caution that a voluntary recall of the Shrek Forever After glasses is appropriate,” the company said.

The recall doesn’t affect the U.K., the company’s British press office said in an e-mailed statement. The “Shrek” glasses were originally intended to be sold in McDonald’s stores from May to June, according to the CPSC. McDonald’s began offering Happy Meals tied to the movie last month in a cross-promotion effort.
