The traditional meat safety system has significantly contributed to public health protection throughout the last century. However, it been recognised that this suffers many flaws – main being its limited ability control currently most important meat-borne hazards. European Food Safety Authority evaluated inspection in context, prioritised hazards and proposed a generic framework for new, risk-based assurance system. aims combine range of preventive measures, applied at farms abattoirs...
Antimicrobial resistance (AMR) is a major threat to public health worldwide. Currently, AMR typing changes from phenotypic testing whole-genome sequence (WGS)-based detection of determinants for better understanding the isolate diversity and elements involved in gene transmission (e.g., plasmids, bacteriophages, transposons). However, use WGS data monitoring purposes requires suitable techniques, standardized parameters approved guidelines reliable prediction their association with mobile...
Abstract A recently discovered source for infection of slaughter pigs, and thus entry bacteria into the food chain, is installed drinking equipment in lairage pens pig abattoirs. To mitigate this, nano-coating stainless steel, currently used human medicine fields as well other parts appears promising technology. In this study, silicon dioxide was applied to six drinkers one three months a abattoir, while results were compared with those that had not been nano-coated. Laboratory examination...
The increasing prevalence of Campylobacter spp. within broiler populations is a major problem for food safety and consumer protection worldwide. In vitro studies could already demonstrate that are susceptible to lauric acid. purpose this study was examine in vivo the influence acid as feed additive on slaughter parameters, muscle fatty profile, meat quality traits reduction coli inoculated Ross 308 (R308) Hubbard JA 757 (HJA) broilers three independent trials (n = 3). Although parameters did...
ABSTRACT Currently, there is no agreed method available for broth microdilution susceptibility testing of Haemophilus parasuis , one the most important bacterial pathogens in pig production. Therefore, aim this study was to develop a that could be easily performed by diagnostic laboratories and appears suitable harmonized testing. Growth determinations using type strain three field isolates revealed visible growth H. media which have proven fastidious organisms. new medium, cation-adjusted...
The traditional meat inspection system is often found to be inefficient. Meat in European countries a phase of modernisation reflect improvements livestock health and advances understanding safety. key point progress replace the with risk-based inspection, including elements safety assurance (MSAS). Modernisation was launched by Food Safety Authority's (EFSA) opinions recommendations period 2011–2013 consequent amendments EU legislation 2014–2019. For this study, EU-funded RIBMINS COST...
Listeria (L.) monocytogenes is a foodborne pathogen that can cause disease, mainly in elderly, pregnant or immunocompromised persons through consumption of contaminated food, including pork products. It widespread the environment and also be found asymptomatic carrier animals, for example, different tissues pigs. To learn more about their nature, 16 spp. isolates tonsils intestinal content pigs 13 from slaughterhouse were characterized using next-generation sequencing (NGS). A wide...
An increasing number of reported detections methicillin-resistant Staphylococcus aureus (MRSA) in food animals since 2007 has led to the assumption that there is an emerging zoonotic problem with livestock associated (la)MRSA potentially aggravating MRSA humans. It was objective study investigate, whether present clinical specimens pigs collected at post-mortem 2004 and further characterize these isolates. We studied 138 isolates S. between from various pathological lesions necropsy....
Bordetella bronchiseptica causes infections of the respiratory tract in swine and other mammals is a precursor for secondary with Pasteurella multocida. Treatment B. conducted primarily antimicrobial agents. Therefore it essential to get an overview susceptibility status these bacteria. The aim this study was comparatively analyse broth microdilution testing according CLSI recommendations incubation time 16 20 hours longer 24 hours, as recently proposed obtain more homogenous MICs....
Abstract Background Escherichia coli carrying clinically important antimicrobial resistances [i.e., against extended-spectrum-beta-lactamases (ESBL)] are of high concern for human health and increasingly detected worldwide. Worryingly, they often identified as multidrug-resistant (MDR) isolates, frequently including quinolones/fluoroquinolones. Results Here, the occurrence genetic basis fluoroquinolone resistance enhancing determinant qnrB in ESBL-/non-ESBL-producing E. was investigated....
Eight Staphylococcus aureus isolates collected from 117 wild boars were characterized and compared to livestock isolates. They belonged sequence types ST133, ST425, the new type ST1643. The spa t1181, t6782, t6384, t6385, t6386. Antimicrobial susceptibility testing microarray-based genotyping confirmed absence of important virulence/resistance genes.
Respiratory diseases continue to pose significant challenges in pig production, and the assessment of lung lesions at abattoir can provide valuable data for epidemiological investigations disease surveillance. The evaluation slaughter is a relatively simple, fast, straightforward process but variations arising from different abattoirs, observers, scoring methods introduce uncertainty; moreover, presence multiple systems complicates comparisons studies, currently, there are limited studies...
Abstract Background European and national administrative legislation require objective evaluation systems for organ lesions at pig slaughter. These results can be used as basis herd health improvement programs by farmers their consulting veterinarians. Various studies have shown that the current recording of authorized meat inspectors are not reliable produce significant inter-rater disagreement especially lung in pigs. The objectives this study were to increase usability official inspection...
The overall objectives of meat inspection are to contribute food safety, animal welfare, and health. In the European Union (EU), there is a request for modernised system that addresses these in more valid, feasible cost-effective way than does traditional system. One part modernisation deals with coding register findings. Although unified standards set at EU level judgement criteria regarding fitness consumption, different national systems force. question extent differences whether basis...
Background Bacteria that have acquired antimicrobial resistance, in particular ESBL-producing Enterobacteriaceae, are an important healthcare concern. Therefore, transmission routes and risk factors of interest, especially for the carriage E. coli. Since there is enhanced pig slaughterhouse employees to carry associated with animal contact as potential factor, present study investigated occurrence Enterobacteriaceae poultry employees. Due higher level resistant primary production than...
Among the organic acids, lauric acid has shown a high level of in vitro activity against Campylobacter jejuni. The prevalence and intensity C. jejuni excretion at slaughter often becomes lower with increasing age. In higher-aged broilers on farms which use other breeds, turn, is sometimes higher slaughter. question then arises as to whether diet concentrations, age alone or genetic breed might have an effect spread experimental infection vivo. Therefore, two complete diets without 2% from...
Extended-spectrum β-lactamase (ESBL)-producing Escherichia coli and methicillin-resistant Staphylococcus aureus (MRSA) represent major healthcare concerns. The role of wildlife in the epidemiology these bacteria is unclear. purpose this study was to determine their prevalence wild boars Germany characterize individual isolates. A total 375 fecal samples 439 nasal swabs were screened for presence ESBL-/AmpC-E. MRSA, respectively. associations seven demographic anthropogenic variables with...
