Genetically Modified Microorganisms Threaten Human and Soil Health; Full Extent of Hazards Not Regulated
An article in Microorganisms by researchers from the U.S., Israel, and Australia analyzes the adverse health and environmental effects of genetic engineering and genetically modified organisms (GMOs), specifically genetically modified microorganisms (GMMs). As the authors state, the prevalence of genetic engineering has “accelerated the creation and large-scale environmental release” of GMMs, which “present unique, long-term risks to human and environmental health.” One of the authors, André Leu, DSc, spoke at the first session of Beyond Pesticides’ National Forum Series: Forging a Future with Nature in 2023.

This review provides risk scenarios of GMMs, showing the threat to ecological systems, particularly within the soil, and human health. As GMMs are “biologically active, self-replicating entities capable of rapid mutation and global dispersal” they present greater risks, and current regulatory frameworks do not adequately assess their potential harm. Genetically altering microorganisms, the most complex and diverse systems in biology, and creating new gene combinations with unknown implications, “has the potential to disrupt the functions, diversity, interactions, and impacts of microbes and microbiomes,” the researchers note.
