BEIJING: Animal feed producers in China commonly add the
industrial chemical melamine to their products to make them appear higher in
protein, state media reported Thursday, an indication that the scope of the
country's latest food safety scandal could extend beyond milk and eggs.
The practice of mixing melamine into animal feed is an "open secret" in the
industry, the Nanfang Daily newspaper reported in an article that was
republished on the Web sites of the official Xinhua News Agency and the
Communist Party mouthpiece People's Daily.
Publicizing such a problem is rare for the Chinese media and appears to be a
tacit admission by China's central government that melamine contamination is
widespread.
The news comes after four brands of Chinese eggs were found to be
contaminated with melamine, which agriculture officials have speculated came
from adulterated feed given to hens. The discovery of the tainted eggs followed
on the heels of a similar crisis involving compromised dairy products that sent
tens of thousands of children to the hospital and was linked to the deaths of
four infants.
That scandal was triggered by dairy suppliers who added melamine, a chemical
used to make plastics and fertilizer, to watered-down milk in order to dupe
quality control tests and make the product appear rich in protein.
Health experts say ingesting a small amount of melamine poses no danger, but
in larger doses, it can cause kidney stones and lead to kidney failure.
It is forbidden to deliberately add melamine to food and animal feed, but its
apparent prevalence highlights the inability of authorities to keep the food
production process clean of toxins despite official vows to raise safety
standards.
The Ministry of Agriculture and the General Administration of Quality
Supervision, Inspection and Quarantine did not immediately respond to faxed
requests for comment. Phones rang unanswered at the Ministry of Health.
Chemical plants used to pay companies to treat and dispose of excess
melamine, but about five years ago began selling it to manufacturers who
repackaged it as "protein powder," the Nanfang Daily report said, citing an
unnamed chemical industry expert. Melamine is high in nitrogen, and most protein
tests test for nitrogen levels.
The inexpensive powder was first used to give the impression of higher
protein levels in aquatic feed, then later in feed for livestock and poultry,
the report said.
"The effect far more exceeds the milk powder scandal," the newspaper
said.
In the past week, melamine has been discovered in at least four brands of
Chinese eggs, and officials in China's largest city, Shanghai, said they had
begun checks on all eggs sold in local markets.
No one has been sickened and it was not immediately clear how many eggs have
been recalled.
China's leading egg processor, Dalian Hanwei Enterprise Group, was among the
companies found producing tainted eggs, which were first identified by Hong Kong
food safety regulators.
The government in the northeastern city of Dalian has said it was first
alerted to the problem of melamine-tainted eggs on Sept. 27. City authorities
recalled problematic eggs, suspended exports and sent inspectors to the company,
according to a notice on the provincial animal health inspection administration
Web site.
Hanwei eggs that Hong Kong authorities found to be tainted came from a batch
produced on Sept. 6, the notice said.
However, mainland authorities have not explained why they didn't immediately
announce the contamination.
The reputation of Chinese products has come under fire in the past year after
high levels of chemicals and additives were found in goods ranging from
toothpaste to milk powder. Chinese authorities and a leading dairy producer
delayed reporting the contamination of milk products for months.
The scandal dealt a huge blow to the Chinese dairy industry. Shanghai-based
Bright Dairy and Food Co. reported a net loss of $39.6 million in the third
quarter, compared to a profit of $57 million in the same quarter a year earlier,
Xinhua said Thursday.
Two other major dairy companies, Mengniu Dairy Group Co. and Yili Industrial
Group Co., saw sales plummet by more than 90 percent after news of the
contamination became public, and expected to suffer losses for the year, Xinhua
said.
The Ministry of Health said Wednesday that 2,390 children remained
hospitalized after drinking tainted milk, including one in serious condition,
and 48,514 had been treated at hospitals and released.
