Sushi that glows in the dark

Daily Mail : Glowing sushi is reportedly a growing fad in the US. The novelties are made with genetically modified zebrafish, called GloFish , sold by Yorktown Technologies in Austin, Texas. Available in an array of colors, including Electric Green, Starfire Red, and Cosmic Blue, the fish were first bred to help detect environmental pollutants but are now available to hobbyists. Their color is produced by a naturally occurring fluorescent protein gene, derived from marine organisms. According to the Glowing Sushi website, one can create a number of interesting dishes with the fish, such as Stop and Glow Nigirizushi, Kryptonite Roll, and Not in California Roll (apparently, California is the only state in the US that does not allow the sale of GloFish). Interestingly, the GloFish website does not support their use as a foodstuff: “GloFish fluorescent fish, like all ornamental fish, are not intended for human consumption. Accordingly, GloFish should not be eaten.”
