Monitoring of Cryptosporidium parvum in fruits, vegetables, herbs and sprout seeds

Popis výsledku v původním jazyce

7th International Giardia and Cryptosporidium conference 23.-26.6.2019 Rouen, Francie – poster, abstract. 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) in samples that come from the markets and farms predominantly from Europe. During five-year monitoring, we tested almost 1100 samples using qPCR assay targeting hsp70. Our results revealed that there were 2.3% positive samples for CP. Fresh vegetables (lettuce, cucumber, carrot) and fresh strawberries were the most contaminated samples with this agent. Even the level of positivity was low this contamination may pose risk of alimentary infection for human health especially for immunocompromised individuals.
