Special Issue Information

Dear Colleagues,

Over the last few years, foodborne and waterborne parasites (FBPs and WBPs) have received less attention than bacteria and viruses and represent a neglected pathogen group. To date, they are increasingly being recognized as a global public health challenge. In fact,  not only have food items and water been found to be contaminated by pathogenic parasites, many of zoonotic concern, in several studies available in the literature, but a significant number of outbreaks linked to their consumption have been reported over the years.

Many changes taking place worldwide can contribute to the spread of FBPs and WBPs: globalization and the movement of people due to tourism or emi-/immigration and the international trade of food products have inevitably increased the risk of acquiring exotic infections.

Social changes are also involved: the growing demand and increased consumption of raw foods and animal products from organic and/or animal friendly breeding environments has led to a rise in parasitic infections.

On the other hand, the lack of harmonized surveillance systems at the national and supranational level and the inadequacy of the currently available diagnostic techniques and reporting systems mean that the spread of foodborne and/or waterborne infections is probably widely underestimated.

Therefore, given the need for scientific research on these neglected pathogens from several points of view, we invite you to submit review or original research articles related to foodborne and waterborne parasites, ranging from surveillance, epidemiology and public health to sampling strategies and detection methods, from diagnosis to prevention and control and from the assessment of viability and infectivity of the parasitic forms contaminating food and water to traditional and innovative methods for decontaminating them.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Pathogens is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Contaminated, raw or undercooked vegetables can transmit parasitic infections. Here, we investigated parasitic contamination of leafy green vegetables sold in local markets in the Tripoli district, Lebanon, during two consecutive autumn seasons (2020–2021). The study involved the microscopic examination of 300 samples of five different types of vegetables (60 samples per type) and used standardized qualitative parasitological techniques for some protozoa and helminths. The results showed that 16.7% (95% interval for p: 12.6%, 21.4%) (50/300) of the vegetable samples were contaminated with at least one parasite. The most frequently detected parasite was Blastocystis spp. (8.7%; 26/300); this was followed in frequency by Ascaris spp. (3.7%; 11/300). Among the different vegetable types, lettuce (23.3%; 14/60) was the most contaminated, while arugula was the least contaminated (11.7%; 7/60). The statistical analysis did not reveal any significant association between the prevalence of parasitic contamination and the investigated risk factors, which included collection date, vegetable type, market storage status, and wetness of vegetables at the time of purchase (p > 0.05). The high prevalence of parasitic contamination also suggested the potential presence of other microbial pathogens. These findings are important because leafy green vegetables are preferentially and heavily consumed raw in Lebanon. Thus, implementing effective measures that target the farm-to-fork continuum is recommended in order to reduce the spread of intestinal pathogens. Full article
