J Parasit: New application of DNA barcode technology

Using a DNA barcode technology for comparative genomics research, scientists can identify different types of parasitic worms and life cycles, so that researchers can make recommendations on whether people ’s food will violate the Jewish dietary rules. Researchers ’research The results have been published in the International Journal of Parasitology recently. In the article, the researchers revealed that although human food contains some nematodes, it still complies with the Jewish dietary rules.

About 75% of pre-packaged foods must be kosher-compliant clean food. Mark Siddall, director of the Invertebrate Museum, said that many non-Jewish people need to find such rules when preparing food. Illegal food, if you are a food supplier, if you do not have such rules, you will face a lot of trouble. This research started in March last year. The researchers put some sardine and capelin eggs into the museum. The focus of the researchers is to see if the emergence of worms will become a sign, or later in sardines and capelin Whether other compliant content can be added to the fish eggs, if it is so, it can be added later.

The key to deciding whether canned food is compliant is the life cycle of the worm. Researcher Siddall said that some types of worms live in the muscles of fish during the larval period, while other types grow in the intestines of fish in adulthood. If we know the growth cycle of these parasites, then we can determine which types of parasites can be in canned food. In order to conduct research, the researchers used genetic barcode technology to efficiently identify any piece of meat, even parasite populations on leather, in a short time.

In this study, the researchers identified many different types of nematodes. None of these nematodes found live in the intestines of fish, so it once again proved that there are no roundworms in fish meat and eggs. In line with the Jewish dietary rules, another author in the article, Sebastian Kvist, said that for research, we are applying DNA barcode technology to issues of public concern for the first time. Scientific research is to help and serve people.
