As much as 40 percent of the samples of smuggled chicken meat and liver taken randomly from markets have been contaminated with Chloramphenicol and Tetracycline residues, said the Food Safety Department. These antibiotics, which are banned from use in breeding and aquaculture, have been detected in more than 10 of the 28 samples of smuggled chicken meat and liver, the department that conducted the testing said. The Ministry of Agriculture and Rural Development previously conducted another inquiry in which the proportion of samples that tested positive for banned substances was lower, at 20 percent. Another test is underway to confirm whether smuggled chicken meat and liver contain growth stimulating hormones, as suspected, or not, the department said. In a related development, market management officers and police in Hanoi have seized a truck that was carrying about 4 tons of live, poor-quality chicken smuggled from China. The seizure was made at the Quang Minh ferry quay in Ba Vi District, Hanoi yesterday morning. Ha Thi Phuc, the goods’ owner, a resident of Hanoi’s Chuong My District, confessed that she had bought the smuggled chicken from a trader named Tien in northern Cao Bang Province. Phuc said she bought these chickens for only VND40,000 (US$1.92) per kilogram, but she could sell them for about VND100,000 per kilogram to traders in the capital. Many traders have engaged in trading illegally imported chicken due to such an attractively high profit rate, concerned agencies said.
