WASHINGTON (AP) Genetically manipulated food remains generally safe for humans and the environment, a high-powered science advisory board declared in a report Tuesday.
The National Academies of Science, Engineering and Medicine concluded that tinkering with the genetics of what we eat doesn't produce the "Frankenfood" monster some opponents claim but it isn't feeding the world with substantially increased yields, as proponents promised.
With the line between engineered and natural foods blurring thanks to newer techniques such as gene editing, the 408-page report said, regulators need to make their safety focus more on the end-product of the food that's made rather than the nuts and bolts of how it's made.
The report waltzed a bit around the hot political issue of whether genetically modified food should be labeled. The study's authors said labels aren't needed for food safety reasons but potentially could be justified because of transparency, social and cultural factors, somewhat similar to made-in-America stickers. That stance was praised by some environmental and consumer groups, but criticized by some scientists as unnecessary because the food poses no unique risks.
There's no evidence of environmental problems caused by genetically modified crops, but pesticide resistance is a problem, the report said. Farms that use genetically modified crops in general are helped, but it may be a different story for smaller farmers and in poorer areas of the world, it said.
Most of the modified plants are soybean, cotton, corn and canola; in most cases, genetic tinkering has made them resistant to certain herbicides and insects. When farms switched from conventional crops to the engineered varieties, there was no substantial change in yields. While experimental results suggest that there should be an increase in production, U.S. Department of Agriculture data doesn't show it, the report said.
Many scientists who work on the issue but weren't part of the study team lauded the report as sensible, but not surprising.
Mark Sorrells at Cornell called it "very well balanced, accurate, and reiterates much of what has already been published many times."
"Science is science, facts are facts," emailed Bruce Chassy, an emeritus professor of biochemistry and food science at the University of Illinois. "There's just no sound basis for their opposition just as there was never any scientific basis to believe GM plants should be viewed any differently than any other,"

Genetically-engineered crops are as safe to eat as their non-GE counterparts, they have no adverse environmental impacts, and they have reduced the use of pesticides. Thats according to a comprehensive report released by the National Academy of Sciences todaya group founded by the U.S. Congress to provide expert scientifically-based advice on a wide variety of issues.
But the academy also found that GE or (genetically-modified organisms or GMO) crops didnt increase those crops potential yields, and they did lead to widespread and expensive problems with herbicide-resistant weeds.
The report acknowledges that beyond safety, other issues need to be addressed, including earning the publics trust. It recommends a more transparent and inclusive conversation about GE crops going forward.
The report, two years in the making, is a 388-page, comprehensive look at every aspect of genetically engineered crops. Sweeping statements about GE crops are problematic because issues related to them are multidimensional, the report says right up front, and goes on to dig deep on those dimensions.
The assessment is generally positive, but there are many caveats and notes of caution. For those of you who want just the big takeaways, heres the nutshell version:
- GE crops are safe to eat. There is always uncertainty about safety, of course, but theres no evidence of harm.
- The GE crops in our food system dont improve on the crops potential yields. They have, however, helped farmer protect yields from insects and weeds.
- Both herbicide-tolerant crops and crops with the organic pesticide Bt built in have decreased pesticide use, although those decreases came early on, and some have not been sustained.
- Increased use of glyphosate, the herbicide GE crops tolerate, has been responsible for a widespread and expensive problem of glyphosate-resistant weeds.
- The report found no adverse affects on biodiversity or danger from interbreeding between GE crops and wild relatives.
- Although both the use of GE crops and the employment of farming techniques that reduce tilling have been on the rise, the report finds no cause-and-effect relationship.
- The economic benefits to farmers have been well-documented, although individual results vary.
- Small-scale farmers may have trouble seeing those economic gains because of the price of seed and lack of access to credit.
- Appropriate regulation is imperative, and that regulation should be based on the characteristics of the crop, rather than the technique used to develop it, whether GE or non-GE.
- Ongoing public conversations about GE crops and related issues should be characterized by transparency and public participation.
