Monitoring of selected zoonotic parasites in fruits and vegetables

Original language description

Hygiena Alimentorum, 15.-17.5.2019, Štrbské Pleso (Slovakia) – lecture and text in peer-reviewed proceedings. Fresh vegetables, fruits, herbs and sprout seeds are usually prepared and consumed raw, without cooking or heating that leads to a risk of foodborne infection. Besides bacterial and viral agents these infections may also be caused by parasitic agents. These parasitic infections are often referred as neglected, although such infections may have had serious consequences for human health. Our goal was to assess the parasitic contamination of vegetables, fruits, herbs and sprout seeds, either raw or frozen. Specifically, the work focused on the detection of Cryptosporidium parvum (CP), Giardia intestinalis (GI) and Toxoplasma gondii (TG). During five-year monitoring, almost 1100 samples of fresh or frozen fruits and vegetables, herbs and sprout seeds were collected and analyzed. Samples originated from fields, fruit farms and markets from Czech Republic but also from other EU countries. We tested the samples using qPCR assay targeting hsp70 (CP), β – giardin gene (GI) and B1 and 529rep loci for TG. Our results revealed that there were 2.3% positive samples for CP. 1.7% of the samples were found positive for GI. DNA of TG was detected in 8.7% of samples. Fresh vegetables (lettuce, cucumber, carrot) and fresh strawberries were the most contaminated samples with these agents. Although the positivity of the samples was not high the occurrence of the parasitic stages is still relevant for human health and can cause clinical illness.
