In the field of bioethics, the introduction of traits such as antibiotic resistance or toxin production into organisms through genetic engineering raises significant ethical concerns regarding safety and potential harm.12

The primary ethical imperative is to protect human and environmental health from unintended consequences. When microorganisms or other organisms are modified to carry these traits, there is a risk that such characteristics could spread or cause unforeseen ecological and health impacts. Ethically, the scientific community and regulatory bodies must prioritize the principle of non-maleficence—the obligation to do no harm—by ensuring that these risks are mitigated through rigorous safety testing and extensive regulatory oversight.21

While these technologies offer potential benefits, such as disease-resistant plants or improved agricultural yields, the ethical challenge lies in balancing innovation with the responsibility to prevent the accidental release of harmful traits into the environment. Consequently, ongoing public and scientific debate remains essential to ensure that the development of genetically engineered organisms adheres to strict ethical standards.13
