Background: Although astroviruses (AstV) have been detected in a variety of host species, there are only limited records of their occurrence in deer. One of the most important game species in Europe, due to its meat and antlers, is roe deer. Infected game animals can pose a threat to the health of other animals and of humans, so more attention nee...

The aim of this study was to examine the relationship between clinical symptoms recorded during the antemortem inspection in the lairage and pathological lesions at postmortem inspection of slaughter pigs. If clinical symptoms were an accurate indicator of pathological lesions at postmortem inspection it could be possible to incorporate only those...

Hepatitis E virus (HEV) is a zoonotic virus that can cause acute hepatitis in humans. Besides the fecal–oral route, transmission can occur by consumption of undercooked pig liver. Genotype 3 is the most frequent genotype found in Europe. Studies on HEV in slaughter-age pigs have not been conducted in Serbia so far. Pork meat production and consumpt...

Introduction. This study assessed the effect of farming system, feeding system, floor type, housing density and gender on the occurrence of pathological lesions in slaughtered pigs. Materials and Methods. The study was conducted on 400 pigs from four farms with different housing conditions. The plucks of 100 slaughtered pigs from each farm were exa...

There is no recommended protocol for detecting and isolating Clostridium difficile present in food samples. Here, we have evaluated the recovery of C. difficile in meat samples after incubating them in various enrichment broths. The media were as follows: cycloserine-cefoxitin fructose broth supplemented with taurocholic acid, d-cycloserine, cefoxi...

Background Group A rotaviruses (RVA) are associated with acute gastroenteritis in children and in young domestic and wild animals. A RVA strain was detected from a roe deer for the first time during a survey of game animals in Slovenia in 2014. A further RVA strain (SLO/D110–15) was detected from a roe deer during 2015. The aim of this study was to...
Article
Hepatitis E is a zoonotic viral disease of pigs with increasing public health concern in industrialized countries. Presented broad study of hepatitis E virus (HEV) presence in pigs in Slovenia is the first attempt to overview the HEV situation in pigs entering a slaughterhouse and, further, to analyse the possibility of HEV entering into the food s...

Hepatitis E (HE) is a zoonosis caused by hepatitis E virus (HEV). The disease that used to be problematic only in developing regions with inadequate water supplies and poor sanitary conditions is now considered one of the foodborne diseases in industrialized countries as well. According to current knowledge, the main reservoir of the virus is linke...

Wildlife is usually not exposed to clinically-used antimicrobial agents but can acquire antimicrobial resistance throughout contact with humans, domesticated animals and environments. Samples of faeces from intestines (80 in total) were collected from roe deer (52), wild boars (11), chamois (10) red deer (6) and moufflon (1). After culture on Chrom...

Purpose The purpose of this paper is to study the microbiological quality of raw milk delivered by 17 vending machines (VM) owned by different Slovenian milk producers. Design/methodology/approach For the determination of hygiene-technical conditions of VM, an observation list that included criteria for estimation of hygiene-technical suitabilit...

Antibiotics have always appeared miraculous, saving innumerable lives. However, the unwise use of antimicrobial drugs has led to the appearance of resistant bacteria. The purpose of this study was to evaluate antimicrobial resistance in Escherichia coli (n=160) isolated from food of animal origin. The focus was on E. coli-producing extended-spectru...
Article
Noroviruses (NoVs) and Hepatitis A virus (HAV) are significant agents of foodborne human viral illness worldwide, both as agents of greatest concern from the consumption of shellfish. In the framework of official national monitoring shellfish samples have been collected since 2013 to determine the spread of NoVs and HAV. Contamination of shellfish...

Food-related bacteria are a very diverse population. They can be found in environment where food and feed is produced and handled. Nowadays, the foodborne zoonoses of greatest concern are campylobacteriosis, salmonellosis and Verotoxigenic Escherichia coli, and antibiotic resistance in these pathogens is an emerging health issue. Studies have been...

Noroviruses are a leading cause of viral gastroenteritis in humans and are responsible for many outbreaks worldwide. Mussels are one of the most important foodstuffs connected with norovirus outbreaks, also resulting in multinational dimensions. Two hundred and thirty-eight (238) samples of mussels (Mytilus galloprovincialis) were collected in peri...
Article
Full-text available
In antibiotic residue analyses the first step of screening is just as important as the following steps. Screening methods need to be quick and inexpensive, but above all sensitive enough to detect the antibiotic residue at or below the maximum residue limit (MRL). In the case of a positive result the next step is conducted and further methods are u...
Article
A survey was conducted to collect preliminary data concerning the prevalence of Yersinia enterocolitica in slaughtered pigs in Slovenia. At the same time, culture procedures for its isolation were compared. During the period between January and May 2008, 1490 tonsil swabs from 149 slaughtered herds were taken from slaughterhouses in Slovenia. One s...

The purpose of the study was to explore the relation between the acceptance of genetically modified organisms, basic emotions, general (IQ), verbal (VIQ) and procedural (PIQ) intelligence. The sample comprised 123 students of psychology (N = 65; 52.8%) and pre-service teachers (N = 58; 47.2%). There were 52 (42.3%) females and 71 males (57.7%) from...

The aim of this study was to determine the prevalence of Vibrio parahaemolyticus in shellfish samples harvested along the Slovenian coast. Shellfish samples of Mediterranean mussels (Mytilus galloprovincialis) were collected along the Slovenian coast at four locations (Seča, Piran, Strunjan and Debeli Rtič) between 2006 and 2008. Samples were exami...

Antimicrobial drugs are not allowed for use in honey production in the European Union (EU). There are no maximum residue limits fixed regarding antimicrobial agents in honey. Discussions are however being conducted in order to set working limits at the European level-for oxytetracycline, 25 ppb was proposed. Tetracycline antibiotics are broad-spect...
Article
Noroviruses are the most common source of gastroenteritis in humans. Genetically very diverse group is classified within the Caliciviridae family. People become infected with noroviruses by contact or ingestion of contaminated food or water. The source of infection may be mussels, growing in contaminated water and accumulating contaminants through...
Article
Listeria monocytogenes is a pathogenic bacterium frequently isolated from food. Especially for people belong to risky population can cause severe diseases with high mortality rate. Of particular concern are the so-called ready-to-eat foods with long shelf-life. L. monocytogenes is often isolated from thermally untreated meat products and also in th...
Article
The main source of the microbes that cause zoonotic diseases in humans are the economic domestic animals. More than a third of all infectious diseases are zoonoses. Although the cause of the infection can be a direct contact with an infected animal or contaminated environment, the most common cause of illness is contaminated food. In Slovenia and e...

Antimicrobial drugs have been widely used in dairy industry for more than five decades generally to prevent or treat mastitis. The detection of antibacterial residues in milk requires screening methods that are simple, quick and sensitive at antibiotic concentrations close to the maximum residue limit (MRL). A new competitive receptor test Twinsens...
