History
The contaminated vegetable proteins were imported from China in 2006 and early 2007 and used as pet food ingredients. The process of identifying and accounting for the source of the contamination and for how the contaminant causes sickness is ongoing.
The first recalls were announced by Menu Foods late on Friday, 16 March 2007 for cat and dog food products in the United States. By 30 March the United States began to ban imports of wheat gluten from China. The Chinese government responded on 4 April by categorically denying any connection to the North American food poisonings refusing to allow inspection of facilities suspected of producing contaminated products.
However, on 6 April 2007, the Chinese government told the Associated Press they would investigate the source of the wheat gluten and by 23 April China gave permission to FDA investigators to enter the country. On 25 April Chinese authorities began to shut down and destroy the implicated factories and detain their managers. The following day, China's Foreign Ministry said it had banned the use of melamine in food products, admitting that products containing melamine had cleared customs while continuing to dispute the role of melamine in causing pet deaths. China also vowed to cooperate with U.S. investigators to find the "real cause" of pet deaths.
The United States Senate held an oversight hearing on the matter by 12 April. The economic impact on the pet food market has been extensive, with Menu Foods losing roughly $30 million alone from the recall.
On 24 April 2007, for the first time FDA officials said that melamine had been detected in feed given to animals raised for human consumption within the United States.
As of 7 May 2007, United States food safety officials stated: "There is very low risk to human health from consuming meat from hogs and chickens known to have been fed animal feed supplemented with pet food scraps that contained melamine and melamine-related compounds"
