Still Undecided About GMOs?

Me too.

On one hand, Genetically Modified Organisms seem great. Altered seeds like Bt Cotton produce plants that protect themselves from their biggest pest therefore reducing the need for insecticides. On both hands, Roundup Ready seeds that allow big farms to spray entire fields with herbicides, which is convenient for them and reduces the need for tilling and the accompanying soil compaction, but has also eradicated Vitamin A-rich weeds in nations whose people depend on them. Then there is Golden Rice - Monsanto's promise to feed and nourish the Vitamin A-deficient folks. While I remain undecided on modified seeds and the controversial patent laws that accompany any discussions around them, I just discovered a whole other wing of GMOs to ponder: Bird Flu Resistant Chickens. Popular Science reports:

Generating flu-resistant birds may be more effective than giving vaccinations to an entire flock, said Dr. Laurence Tiley, a veterinarian and lecturer in molecular virology at the University of Cambridge, England, one of the authors of the chicken study. Vaccinated birds may not develop flu, but the virus can still replicate in their bodies and be transmitted to other unvaccinated fowl, he explained in a podcast with the journal Science, which publishes the study tomorrow. Besides, just like with human influenza, there are plenty of strains, and vaccines don’t cover all of them.

The new genetic modification is basically the opposite — birds will still get sick and die, but they won’t pass on the virus to other birds, a major advancement for animals that generally live in very close quarters. The lack of transmission also means the virus will be less likely to spread to people.

Questioning safety of Roundup

New research has revealed that an inert ingredient in the popular weed-whacking herbicide, Roundup, can also suffocate human cells, particularly embryonic, placental and umbilical cord cells, in a laboratory. Crystal Gammon, for Scientific American, reports:

Glyphosate, Roundup’s active ingredient, is the most widely used herbicide in the United States. About 100 million pounds are applied to U.S. farms and lawns every year, according to the EPA.

Until now, most health studies have focused on the safety of glyphosate, rather than the mixture of ingredients found in Roundup. But in the new study, scientists found that Roundup’s inert ingredients amplified the toxic effect on human cells—even at concentrations much more diluted than those used on farms and lawns.

The research team suspects that Roundup might cause pregnancy problems by interfering with hormone production, possibly leading to abnormal fetal development, low birth weights or miscarriages.

Monsanto, the product's manufaturer, contends that the study does not reflect realistic usage and conditions of the product. And the EPA classifies classifies glyphosate as a Group E chemical, which means that there is fairly strong evidence it does not cause cancer in humans.

As with any data and contraversy, I feel obligated to err on the side of caution and suggest that expecting mothers steer clear of Roundup.
