Police in the Central Highlands town of Da Lat are investigating an alleged food safety violation after cooks at a boarding school found a piece of an apparent injection needle in a piece of pork.
The kitchen staff at Lam Dong School of Hearing Impaired Children said they found the piece of two centimeters long while preparing meals for more than 100 students and teachers at the school on Tuesday.
Police have taken the needle and the pork for testing, Tien Phong newspaper reported.
A source from the school said they have been buying meat and vegetables from a vendor at a local market since 2015.
Lam Dong Province officials have not commented on the case.
Pigs injected with chemicals to increase weight and the proportion of lean meat has been a widespread food safety problem in Vietnam. The substances can be passed on to consumers and cause cancers over several generations.
Starting July farmers who use illegal chemicals in animal farming and sellers who are aware of such practices can be punished with imprisonment, instead of only cash fines.
