Final answer:
When a new transgenic plant or GE microbe is approved by the EPA for marketing, it is considered 'deregulated,' meaning it has passed safety assessments and can be commercially used without stringent regulations.
Step-by-step explanation:
When a new transgenic plant or GE microbe has been evaluated by the EPA and approved for marketing, it is said to be deregulated. This implies that the plant or microbe has undergone rigorous testing and has been deemed safe for environmental release and commercial use.
These organisms, often created through genetic engineering to possess new genes that code for traits beneficial to humans, are initially regulated to prevent ecological harm and ensure safety for human consumption. The process includes an assessment of potential risks to human health and the environment.
Evaluations by reputable organizations, including the US National Academies of Sciences, Engineering, and Medicine (NASEM), and findings mentioned in the NASEM's GE Crop Report, play a significant role in determining the safety of these genetically engineered crops.
Once deemed safe and approved, these transgenic crops can enter the market and be grown without the strict oversight previously required during their regulated phase.
