摘要：You might have heard that animal experiments are performed in scientific research and wonder why. Regardless of your personal opinion on animal use in research, you have certainly already benefited from it. This is because all substances that end up in food or medicine have to be thoroughly tested for potential to cause harm. For this, the substance must be tested in animals before being tested in human volunteers or approved for general use, although animal testing for cosmetics has not been allowed within the EU since 2009. However, it would be ideal to find a better way of testing whether a substance is harmful or not. In this article, we will briefly summarize why animals are used in research and what kind of alternatives might potentially be used in the future.
