WASHINGTON, Aug. 30 The U.S. Food and Drug
Administration is weighing whether to allow a genetically
engineered Atlantic salmon to be the first such animal to be
sold as food. [ID:nN3090447] The fish is made by Aqua Bounty
Technologies Inc ABTX.L
The following are four other genetically engineered animals
in development or approved by the FDA.
University of Guelph scientists are awaiting word from the
FDA on their Enviropig, a type of Yorkshire pig with genes
altered to affect digestion. They hope it will be the second
FDA-approved genetically engineered food animal.
The pig is engineered with a mouse protein that affects its
saliva. The aim is to create more environmentally friendly
manure by reducing the amount of phosphorous the pig excretes
after eating cereal grain. Phosphorous can leach into waterways
and increase the amount of fish-killing algae.
MAD COW RESISTANT CATTLE
Hematech Inc in Sioux Falls, South Dakota, is developing
cows that are resistant to "mad cow" disease (bovine spongiform
Called TC Bovine, the cows could help researchers develop
treatments for some human illnesses, according to Hematech,
which has said the cow could be a food source.
Researchers said they developed the cow by "knocking out"
the prion protein gene that can trigger "mad cow" disease.
Hematech is a subsidiary of Kirin Holdings Co Ltd's
(2503.T) Kyowa Hakko Kirin Company.
In February 2009, the FDA approved GTC Biotherapeutics
Inc's GTCB.OB modified goats used to produce an anti-clotting
therapy for people with a rare disorder called hereditary
antithrombin deficiency. The drug, Atryn, is made with human
protein from female goats bred to express it in their milk.
The company, in Framingham, Massachusetts, has said its
roughly 200 goats are bred using cells injected with human DNA.
The drug is licensed in the United States to Lundbeck Inc
In December 2003, the FDA said there was no reason for it
to regulate the GloFish, a zebra danio fish genetically altered
with fluorescent colors, because it was not intended for food
and posed no environmental threat.
The fish was originally developed to help detect polluted
waterways using a fluorescent protein gene that occurs
naturally in other marine organisms, according to Yorktown
The company sells the fish nationwide except in California,
which required a formal environmental study that Yorktown said
was too expensive.
