What is being called the ‘world’s first ever comprehensive and independent study on the safety of GMOs and their associated pesticides’ is expected to launch in 2015. At a cost of around $25 million, this international effort will be an approximately three year study of rats with the goal of answering these questions:
Are GMOs (or their associated pesticides) toxic to organ systems over the long-term?
Do GMOs (or their associated pesticides) cause cancer?
Do GMOs (or their associated pesticides) reduce fertility or cause birth defects?
Is the mixture of chemicals present in Roundup herbicide more or less toxic than its active ingredient glyphosate?
This is a BIG deal. Monsanto had used a 90 day study which showed no ill effects, while a two year study by others showed tumors in the rats (only detected after around 18 months) – source. A three year study will help address the concerns raised by that two year study, and may also lead to regulators requiring long term studies for future GM products (currently, long term studies are not required in any country).
Thanks to glyphosate-resistant genetically modified seeds from Monsanto, farmers in the US have been able to vastly increase their use of glyphosate (the main ingredient in the weed-killer RoundUp), and hasten the evolution of common weeds into new, herbicide-resistant superweeds. These SuperWeeds are out of control in areas of the midwest and Kansas. Well done, farmers!
This is exactly the sort of outcome logic would predict, so let’s hope they intended to do that and aren’t instead just focused on their short-term profits. Umm, yeah. I think the only surprise would be that the weeds adapted so quickly…I’m sure Monsanto was hoping for a few more decades of profits to be had from that RoundUp/Seed combination!
There’s a new category of genetically modified crops on the horizon that utilize a technique known as RNAi, or RNA interference. For a recap of what RNA does, check out wikipedia, but in summary: it’s primarily a messenger, carrying instructions from DNA to control the synthesis of proteins. RNAi is an attempt to interfere with this process; an insect (the corn root worm, in this case) takes up small siRNA (small interfering ribonucleic acid molecules) from a corn plant, which then turn off the production of critical proteins in those pests, killing them. It’s a pretty amazing technology, and one that’s also being explored in the fight against cancer, to interfere with cell division of cancerous cells.
So there lies the concern. The medical field is looking at ways to help the human body absorb those siRNA molecules. The food industry wants the opposite, for there’s justifiably a lot of uncertainty and concern about the effect this may have on the body. Some scientific studies have indicated that the body might be absorbing this, most find no evidence of that. It seems much of the uncertainty comes from the difficulty in detecting these very small molecules in the first place. There is also uncertainty about what other insects may be harmed by this (one study found that ladybugs were one victim). On the plus side, this has the potential to reduce or eliminate two techniques currently employed – spraying crops with Roundup (that then gets into our food supply), or using corn that is genetically modified to produce BT Toxin (which we then consume).
Monsanto is convinced they’ve studied the issue enough, and have applied for approval to sell this new corn variant. There still seems to be quite a bit of valid scientific debate over that subject…but if history has taught us anything, it’s that big business will win out over science and public health concerns.
With all the news about GMOs…what do you really know about them? Ignoring the health concerns for a moment, it’s good to look at some facts about how widespread they are, and that’s what this article at the WSJ does. Some key points:
GMO crops have grown, on average, by 10 million hectares a year since 1996 (when they were introduced).
Most of the world’s GMO crops consist of four types of plants: soybeans (48%, by acreage)), corn (33%), cotton (15%), and canola (5%).
Five countries are responsible for about 90% of GMO crops. US (40%), Brazil (23%), Argentina (14%), India (6%), and Canda (6%) – leaving other countries at 11% total.
In the US, most major crops are GMOs, more than 90% of our top crops like corn, soybeans, and cotton. I think that goes a long way towards explaining opposition to GMO labeling!
Over 75% of GMO seed designs are owned by 10 companies (some of those are GM, some are non-GM but still considered proprietary). Selling seed is a $34.5 billion business.
You can read more at the WSJ article linked above. I’m a huge fan of using science to improve our lives, but believe it cannot be selective science like GMOs are. What I mean is, new seeds are designed, but long term health effects are not adequately studied before the seeds are introduced to market. Instead, seeds are put on the market, making us all guinea pigs, but without adequate control of the variables, any health concerns that may someday surface cannot be accurately tied to any single crop. There can be no accountability, and with neither accountability nor laws requiring extensive testing, there is no incentive for companies to be sure their products are human-safe. While some GMO efforts are likely benign, the idea of engineering corn to produce poison to kill insects for example (read up on BT Toxin)…and then telling us it’s OK for us to eat that poison…that’s a real stretch.Oh, and that picture of a blue strawberry? That’s not photoshop, that’s GMO at its finest, and you can read more about that here.
High levels of glyphosate (the weed-killing chemical in Roundup) have been found to be present in genetically engineered soy beans (all tested samples were grown in Iowa). It’s not terribly surprising, for one of the main reasons crops like soy are genetically engineered in the first place is to be resistant to Roundup, so that they may be sprayed with that to control weeds. The chemicals get on the food, the food ends up on your plate…simple as that. It’s not something you can just wash off either, as glyphosate is absorbed by the plant, it’s inside your food.
The study (here’s a link to the source) found levels of Roundup to be 9mg per kilogram, which is double what Monsanto themselves deemed ‘extreme’ way back in 1999 (link). The level deemed ‘safe’ by governments is 20mg/kg in the US…but the interesting thing is that it used to be 0.1mg/kg until it was raised in 1999. Europe did the same, raising the ‘safe’ limit from 0.1 to 20mg/kg in 199. Brazil raised their ‘safe’ level from 0.2mg/kg to 10mg/kg in 2004 (but only for soybeans!). There is justifiably concern that the ‘safe’ levels were not raised based on scientific evidence, but rather for business reasons.
The study looked at a total of 31 soy samples, some were GM (qty 10), some were conventional soybeans (qty 10), and others were organic soybeans (qty 10). Without exception, all GM samples showed high levels of glyphosate, and none was detected in the non-GM samples.
So why is this a big deal? Well it’s not a chemical that has been scientifically shown to be safe…and quite the opposite, there are concerns that there may be a link between glysphosate and digestive issues, obesity, autism, Alzheimer’s, depression, Parkinson’s disease, liver disease, and cancer. Note that none of that is proven, just that there does appear to be some biological disruption caused by glyphosate, and that sort of biological disruption may explain the above. There’s a bunch of health-related information at this link or this one.
This trend of shipping untested product like this and making us all human guinea pigs is really disturbing. The reality is that if there IS any link here ever proven, it will be impossible to hold anyone accountable. Hence no incentive for people to do real, scientific testing beforehand.
It probably goes without saying, but…I recommend buying organic food whenever you can!
Well I think the title says it all…Monsanto’s Roundup herbicide is really nasty stuff that studies are showing has a link to some really nasty human diseases. Add to that the increased use of crops that have been genetically modified to be roundup-resistant, and you should start being concerned about the safety of your food supply. Do yourself a favor and either buy organic foods, or grow your own vegetables! (read more at The Good Human)
It’s hard enough to avoid GMO foods when there are no laws requiring the labeling of them, but it’s harder once you learn that other common ingredients may be manufactured from GMOs. For example: if you see maltodextrin in the list of a product’s ingredients, know that most of that is made from GMO corn (unless the product is labeled as “USDA Organic”). Vitamin C is another GMO corn product (mostly). Same with ascorbic acid. Will these GMO products cause you harm? That’s the big question, and frankly until the scientific testing has been done to show that a particular GMO crop is safe to eat, it’s best to avoid this stuff (IMHO).
