According to the study, eggs of the alveococcus — a tapeworm capable of causing severe diseases in humans and domestic animals — were found in almost 17% of samples of local strawberries. Experts recommend thoroughly rinsing the berries under running water before consumption. Professor Urmas Saarma from the University of Tartu explained that the adult parasite is only a few millimeters long, but its larvae pose a serious danger. When they enter the human body, they can migrate to the liver, where they form parasitic formations. According to the scientist, among European countries, the highest number of alveococcus eggs was found in samples from Estonia, followed by Latvia in second place and the Netherlands in third. The source of the parasite's spread is dogs, cats, and other members of the canine and feline families. Their feces can contaminate the soil and water, after which the parasite's eggs end up on cultivated berries and vegetables. The authors of the study emphasize that precautions should be taken not only when consuming strawberries but also any berries, fruits, and vegetables grown in gardens or greenhouses. It is recommended to wash all such products thoroughly before eating. For those who grow berries and vegetables themselves, specialists advise limiting access for pets to the areas with the harvest as much as possible.
