Why this genetically modified mushroom gets to skip USDA oversight
Key Excerpts from Article on Website of Washington Post

For the first time, a food product created using CRISPR a promising but controversial gene-editing technique could be on track to be sold and eaten. And it might be the first of many. Last week, the U.S. Department of Agriculture (USDA) confirmed that it will not regulate the cultivation and sale of a white-button mushroom created using CRISPR. The decision came in the form of a letter to Yinong Yang, a plant pathologist at Pennsylvania State University who created the new mushroom. Yang's frankenfungi is a simple Agaricus bisporus, the kind of white-button mushroom you could buy at any grocery store. But Yang targeted several genes that code for the protein that causes mushrooms to turn brown as they age or get bruised. The result is a mushroom more resilient to automated harvesting and long storage periods. If you support the labeling of GMOs, the USDA's decision to wave this shroom in without a second thought might strike you as scary. If Yang had tackled mushroom browning by adding bits of genetic code from another organism, it would have been subject to USDA scrutiny as other non-browning produce has been. Until recently, genetic modification required the insertion of foreign viruses or bacteria, but CRISPR is more advanced than that. Because of that loophole, it's not under the USDA's jurisdiction. The EPA only regulates GMOs designed for pest control, and the FDA considers all GMOs to be safe. That leaves this non-browning mushroom cleared for take-off.
