"The arrests came as Cadbury recalled Dairy Milk bars and other chocolates from across the Far East after traces of melamine were found in its Chinese made chocolates.
State media Xinhau reported that more than 480lb of the industrial chemical melamine was seized during raids.
The arrests took place in Hebei province and Chinese media reported that a police investigation showed that melamine had been produced in underground plants and then sold to farms and milk purchasers.
Cadbury had earlier said it was recalling 11 types of Chinese made products after tests found they contained melamine.
A Cadbury spokesman said it was too early to say how much of the chemical was in the chocolates."
