This week, local officials in the Florida Keys will decide whether to approve the first ever release of genetically engineered (GM) mosquitoes in the United States. Yes, you read that right: lab-engineered mosquitoes could be released in one of America's favorite tourist destinations very soon, even though it's unclear if any government agency has evaluated the full array of health and environmental risks associated with these new GM insects.
Unfortunately, the Florida Keys Tourist Development Council (TDC) and the Monroe County Board of Commissioners have been conspicuously absent from the conversation about GM mosquitoes even though this experiment could have a direct impact on business in the Keys. The proposal to release millions of these mosquitoes by British company Oxitec is instead being vetted by a small, local board called the Florida Keys Mosquito Control District. This mosquito district has touted GM mosquitoes as a potential boon to tourism in the Keys because they could reduce dengue fever, though the Keys haven't had a case in a half-decade.
Of course, Florida's mosquito problem should not be trivialized. Dengue fever is a leading cause of illness and death for those in tropical and subtropical climates, according to the Centers for Disease Control. But Oxitec has not provided evidence to support that its mosquitoes will be able to effectively control dengue. On the contrary, reports from the field suggest the opposite. Malaysia's Health Minister recently announced that after field-testing Oxitec's mosquitos, the country will not be pursuing the program because it was not cost-effective. Additionally, one Brazilian town was still at the highest alert for dengue fever even after Oxitec's mosquitoes were released there in 2013.
Even if these bugs did successfully wipe out the entire population of the targeted A. aegypti mosquito, the Asian tiger mosquito (also a known vector of dengue and other diseases) could easily take its place. Letting tiger mosquitoes become more commonplace would only make a new dengue fever carrier more prevalent.
Oxitec claims that its mosquitoes are engineered with a lethal gene that is supposed to break the pest's reproductive cycle because its offspring, for the most part, die before reaching adulthood. The company claims this would theoretically reduce the mosquito population and the prevalence of dengue fever without the need for pesticides. But the Mosquito Control District has not done enough to identify insecticide alternatives. Instead of exploring a range of options, they have hastily and aggressively pursued Oxitec's GM mosquito program despite strong public opposition and a lack of peer-reviewed data.
Significant public opposition defeated Oxitec's first plan to release GM mosquitoes in Key West in 2012, but Oxitec is now poised to win approval in Key Haven, a peninsula just a few miles east of Key West. Hundreds of thousands of citizens from across the country have written local, state and federal officials to oppose this plan and last week, hundreds of people called the local tourism council to ask that the Keys be preserved as a national treasure for tourists and residents alike, not for GM mosquito experiments.
It is puzzling that any local official would sit on the sidelines while GM mosquitoes were allowed to potentially tarnish the reputation that most Americans have of the Florida Keys as a pristine island paradise. But that is exactly what the Florida Keys Tourist Development Council and the Monroe County Board of County Commissioners have been doing.
It's high time that local officials took decisive steps to stop this bizarre plan now instead of inheriting the more difficult task of attracting visitors to a place where residents and tourists are the subjects of a science experiment. It's clear now that GM mosquitoes could not only potentially harm public health and the environment -- they may also be bad for business.
