The US House of Representatives passed by a vote of 306 to 117 a bill that establishes mandatory, nationwide labeling requirements for food products containing bioengineered ingredients. The Senate passed the bill by a 63 to 30 vote on July 7. The bill was sent to President Barack Obama for his signature. It was expected the president will sign the bill into law. The bill nullifies the Vermont mandatory GMO labeling law that took effect July 1. The bill requires food manufacturers to disclose the presence of bioengineered ingredients in one of three ways: text on the package, a symbol on the package or a link to a web site (a quick response code or similar technology).
