toxic yellow croakers purposefully dyed a fresh yellow were seized .....

Their seizure comes in the wake of the incident at the end of last year, in which fish in Shanghai were dyed a toxic malachite-green. It is widely being seen as yet another serious case of the lack of food safety......

Tinting fish and animals a certain color to increase market appeal is apparently a common practice in China.

Another reason to question the safety of importing food from China.
