Raw Tuna fish slices -  how do you choose for 100% safety ?? 
     No  too beautiful-color ones !    No dark brown (tan) ones !

 

University studies (高雄海科大) found that 80% of raw fishes (Cobia, Tuna, Sword-Fish, Tilapia 鯛) in Taiwan market were stained ――  business men pump CO. (carbon monoxide) into those fishes in an enclosed space for beautiful or bright color look /  CTS TV news, 2-20-'06
Fishes adding CO is illegal in Europe, Canada, Korea, Japan, Singapore, etc, because of possible food-poisoning, or even causing Sepsis to die / Epoch Times, 2-20-'06 

TVBS 8-15-2018: M.D.江守山 commented Taiwanese government ignoring pumping CO into fishes which is illegal in Taiwan (法律禁止  政府未執法) ,  therefore Taiwanese have risk of eating slough and some unknown consequences.   Some other business people used chemical addictives (e.g., 檸檬酸鈉) to keep raw-fish's color unchanged.   Red meat fishes after being frozen are still "bright red" colour might be "processed" meat.  (ref. to 《食在安心》book by 江守山)
