Answer:
The potential risks associated with plant-based pharmaceuticals include: pollen transfer to related species, contamination of non-transgenic crops intended for the consumption by humans, allergic reactions to the drugs produced from the genetically engineered plant, and persistence of genetically engineered material to persist in the environment and accumulate in non-target organisms. Risk assessment of plant-made pharmaceuticals should be reviewed on a case-by-case basis because the plants used to produce proteins each have different risks associated with them. 
 
        
             
        
        
        
A genetically modified organism (GMO) is any organism whose genetic material has been altered using genetic engineering techniques. The exact definition of a genetically modified organism and what constitutes genetic engineering varies, with the most common being an organism altered in a way that "does not occur naturally by mating and/or natural recombination". A wide variety of organisms have been genetically modified (GM), from animals to plants and microorganisms. Genes have been transferred within the same species, across species (creating transgenic organisms) and even across kingdoms. New genes can be introduced, or endogenous genes can be enhanced, altered or knocked out.
