If you want to introduce new food items, drugs, or any such thing, you have to get them tested before you apply them on humans. And as per the current status of development in the biological sciences, we don't have any other opinions other than testing them on animals.

In order to launch any new consumable products, whether it is any food item or any medicine, they are to be tested in any way prior to applying on human to prevent any harm on them, nevertheless, scientists have at best choice of applying new things on animals. This essay opines that this argument is logical provided that human being is too invaluable to get affected by any negative consequence of brand new foodstuffs which were not tested prior with evidence. Moreover, If new food items/ medicines are to apply on individuals without any prior experiment result, it could hamper individual's inner body indirectly and might pass any disease on their next generation. Initially, it is frightening for many that any new foods/ medicine items would be applied on human at first because there is possibility for them to be infected, if not all, but a percentage for sure. Despite the fact that adept professionals are allowed to introduce any new medications or food items, it cannot be believed that the creations are 100 percent error free and can be consumed with blind eye. Even if one person is impacted through any virus or harmful object through the creations, they won't be trusted at all. Therefore, the new project might fall apart as well. To illustrate this, British scientists injects a potion to rabbits before introducing to public so that they can rectify any mistakes if any infection happens to those animals and then they launch them to world. Following this, because the scientists would have no proofs that the the original foods/ drugs will not impact individuals body indirectly as well if they don't test them before, they might cause harm to a person's gene and the danger could travel through the affected individual's descendants. Any latest medications or edibles may contain any unknown disease that might consequence in, if applied to a human, transferring that illness to his next generation. For instance, There was an experiment going on in Bangladesh after 1971 injecting a polio virus dose to children aged five to 10, where, 10% seemed to have some physical ailment afterwards. Furthermore, 2 percent of them have had physically challenged children in next twenty years. To recapitulate, new foodstuffs or medicines are required to be experimented on animals beforehand because it might transfer disease to generations ahead, if firstly tested on human, and they may infect human as well.
