SAFAKNA TURKEY – KU Faculty of Fisheries, Department of Fundamental Sciences of Fisheries, Associate Professor, Assoc. Dr. Sedat Gündoğdu studied 33 different brands of tuna from 7 producers in the Turkish market to identify the presence of microplastics in processed seafood. Gundogdu studied tuna in the laboratory using a light microscope and a micro Raman microscope.
Assoc. Dr. Gündogdu said: “Based on the hypothesis that processed seafood may be contaminated, we collected 33 different varieties of tuna from 7 different producers to understand the extent of this situation in Turkey. We investigated the presence of microplastics in them. We have determined that every can of tuna contains at least one microplastic, even if the amount is small compared to samples in the world. “The results showed that packaging and manufacturing processes are the main possible sources of microplastics.”
FROM PLASTIC TO PACKAGING
Pointing out that the plastic pollution found in tuna is mainly caused by packaging, Assoc. Dr. Gündogdu continued, “When we analyze the packaging materials separately, the structure of the microplastics coming out of the tuna, especially the metal packaging
We have seen that the materials used in covering the inner surface of the js have the same structure. This study showed once again that it is necessary to move away from plastic in packaging and use materials that do not harm the environment and human health. Chemicals used in the production of plastics may come into contact with food due to such packaging. Similarly, we can say that microplastic pollution comes from the sea in processed seafood produced from the sea. The main problem here is related to the intensive production and use of plastic.”
HORMONAL DISTURBANCES AND CARCINOGENIC CONSEQUENCES
Claiming that the work environment is also an important source of pollution, Assoc. Dr. Gündogdu said that in some samples they came across pieces of gloves used during work. Assoc. Dr. Gündogdu explained that it is necessary to eliminate the main sources of environmental pollution in terms of microplastics, as well as pay attention to hygiene in terms of bacterial and microbiological aspects.
Emphasizing that plastics also contain chemicals that destroy hormones and have a carcinogenic effect, Assoc. Dr. Gundogdu noted that such a situation can cause various problems with human health.
