Safe "Engineered" Fugu, Sans Gene Manipulation 55
zlel writes "Did anyone figure that you could get clean, poison-free Fugu without genetic engineering? According to this story, a group of researchers at Nagasaki University managed to do just that - they bred Fugu by giving them poison-free feed. They tried to get Japan to modify its ban on the sale of Fugu liver - but authorities felt that this was too big a risk - so in the meantime, you gotta trust your chefs." Anyone willing to translate for the Japanese-impaired?
