Fish products, especially fish, have an important place in human nutrition. Fish meat is an important potential in terms of increasing population and meeting the need for animal protein, but in addition to its benefit, fish meat has risks due to various factors. These risks, in particular, lead to poisoning and infections in humans due to residues, and break the body's resistance to cancer. Therefore, the antibiotics used in the farms and the associated residual risks threaten human health.

Antibiotics in animals are used to treat some diseases. In addition, antibiotics are given to healthy animals in order to increase growth rates and increase feed yield. The antibiotic used in this way passes into the milk by mixing with the blood, especially in animals that give milk. Drugs containing antibiotics are excreted from the body of the animals after a certain period of time. However, there is antibiotic residue in the milk taken from animals during this period. In fact, these milk should not be used.

In the milk containing antibiotics, bacteria that do not develop fermented products such as cheese, yoghurt cannot develop, or because the process is not fully realized, low quality products are obtained and product losses occur. In addition, various microorganisms in the human body gain resistance and treatment with antibiotics becomes difficult when it is really needed.

For this reason, any kind of food producer companies or farms are required to carry out some test and quality control studies at various stages of production until the products reach the consumers.

In laboratories, Elisa method is also used for antibiotic tests within the scope of chemical tests. The Elisa test is used to quantitatively detect antibiotic residues in human muscle and liver tissues, fish, shrimp and crab tissues, or foods such as milk, eggs and honey. In these studies, the standards prepared by local and foreign organizations are complied with.
