New data from a simple survey of 55 vendors in 14 states indicates farmers are planting more GMO sweet corn for the fresh market (corn on the cob) than previously thought. IRT volunteers visited both farmer’s markets and grocery stores. 31 vendors confirmed the sweet corn was GMO; 24 confirmed that it was conventional non-GMO. Not included in the data is the availability of organically grown sweet corn.
In several instances (not included in the results), the origin was unknown, or the vendor did not want to say it. While the data is by no means conclusive, or representative of the entire U.S., one thing is clear: before you buy those roasting ears, you really should ask, “is this non-GMO?”
Data for frozen or canned corn is very difficult to obtain because processors combine batches of raw corn from several suppliers. You may almost be assured that fresh frozen or canned corn – especially yellow corn – is mostly GMOs. Certified organic is the way to go.
Sweet corn varieties have more sugar and less starch. Raw sweet corn is classified as a vegetable.
Field corn is also used to make corn chips and tortillas, cereals too! Choose organic or visit Non-GMO Project for verified non-GMO brands.
Over 94 million acres of field corn were planted in the U.S. in 2016. Of that, approximately 92% was planted with GMO biotech varieties including both herbicide-tolerant and Bt traits. For detailed use of field corn, see this report from the National Corn Growers Association.
The researchers, affiliated with the Committee for Independent Research and Information on Genetic Engineering (an independent, nonprofit association dedicated to studying the impacts of genetically modified organisms), published their detailed critique of the Monsanto studies in the International Journal of Biological Sciences (2009; 5:706-726). They concluded that the data — which Monsanto claimed proved the corn varieties were safe to eat — actually suggest potential kidney and liver problems resulting from consumption of all three modified corn varieties, as well as negative effects on the heart, adrenal glands, and spleen. The findings confirm a 2007 report from the same researchers on a single variety of modified corn.

Sweet corn is a beloved staple in many kitchens, known for its crisp texture and naturally sweet flavor. To enjoy it at its best, it's important to know how to choose and store it properly. Here are some tips to ensure your sweet corn stays fresh and delicious. Choosing the Perfect Sweet Corn Look for Green Husks: When picking sweet corn, start by checking the husks. They should be green color and tightly wrapped around the cob. If you notice any brown or dried-out husks, it's a sign that the corn isn't fresh. Feel for Firm Kernels: Give the corn a gentle squeeze through the husk. The kernels should feel firm and plump. If they’re mushy or shriveled, put that cob back – it’s past its prime. Check the Silk: The silk (those thread-like strands coming out of the top) should be slightly sticky to the touch and look fresh. Depending on the variety of sweet corn, the color can range from light to dark, so focus more on its condition rather than the specific color. Check for Insects: Look for any small holes or damaged areas on the husk. These could be signs of insect infestation. A clean, undamaged husk is what you’re aiming for. Storing Sweet Corn Refrigerate Immediately: Corn starts to lose its sweetness as soon as it’s picked, so refrigerate it as soon as possible to preserve its flavor. According to the University of Illinois Extension, corn can lose up to 50% of its sugar within 24 hours if not refrigerated. Keep the Husks On: Store the corn with the husks still on. They act as a natural protective barrier and help retain moisture. Reader testimonial: “I’ve always kept the husks on my sweet corn before storing it, and it’s remained fresh and flavorful for several days.” Use a Plastic Bag: Place the ears of corn in a plastic bag to keep them from drying out. Make sure the bag is closed tightly. Freeze for Long-Term Storage: If you can't use the corn within a few days, remove the…
