Q. I like to feed the birds but am concerned about offering genetically engineered seeds. Are any birdseeds engineered?

A. Genetically engineered varieties of most birdseed ingredients have not been commercialized. An exception would be any mix containing corn; genetically engineered corn is widely planted.

The Union of Concerned Scientists (www.ucsusa.org/food_and_environment/genetic_engineering/engineered-foods-allowed-on-the-market.html) lists the following crops as having genetically-engineered varieties on the market, so you can check birdseed ingredients:

alfalfa
canola
chicory
corn (sweet, pop and field)
cotton
flax
papaya
potato
rice
soybean
squash
sugar beet
tomato

Two excellent resources for keeping up with issues surrounding genetically-engineered crops are GE Free Maine (www.gefreemaine.org) and The Organic & Non-GMO Report (www.non-gmoreport.com).
