(Dec. 21, 2011) A private firm is planning to release potentially harmful genetically engineered mosquitoes in the Florida Keys as early as January, endangering human health and the environment in what would become the first-ever U.S. release of these engineered bugs.

The genetically engineered mosquitoes, Aedes aegypti, are produced by UK-based biotechnology company Oxitec so their offspring will die at a young age in an effort to lower mosquito populations and limit the spread of dengue fever.

While attempts to limit the spread of disease are laudable, health, environmental and ethical challenges face what would be the first-ever release of genetically engineered mosquitoes in the U.S.

Genetically engineered mosquitoes have already been released by Oxitec in the Cayman Islands, Malaysia and Brazil. Despite claims that its mosquitoes are sterile and have eradicated dengue fever the mosquitoes are in fact fertile and Oxitec has never successfully eradicated dengue fever from any population.
