Vermont Gov. Peter Shumlin on Thursday signed a bill that makes the state the first in the U.S. to require labeling of biotech foods. The law will take effect July 1, 2016. BIO, which is supporting a proposal that would nullify any mandatory biotech food labeling efforts in the U.S., said such labeling would raise food costs, confuse consumers and imply that biotech foods are not safe for consumption. "Scientific bodies and regulatory officials around the world recognize that foods made from genetically modified (GM) crops are as safe as their non-GM counterparts. GM crops have enabled farmers to produce more on less land with fewer pesticide applications, less water and reduced on-farm fuel use," said Cathleen Enright, BIO's executive vice president for food and agriculture.
