Abstract Listeria monocytogenes (in the meat, fish and seafood, dairy fruit vegetable sectors), Salmonella enterica feed, egg low moisture food sectors) Cronobacter sakazakii sector) were identified as bacterial safety hazards most relevant to public health that are associated with persistence in feed processing environment (FFPE). There is a wide range of subtypes these involved FFPE. While some specific more commonly reported persistent, it currently not possible identify universal markers...
Salmonella is the second most commonly reported zoonotic gastrointestinal pathogen in European Union, and a significant proportion of cases are linked to consumption contaminated pork. Reduction at farm level helps mininimise contamination pressure slaughterhouse, therefore number bacteria entering food chain. Cleaning disinfection (C&D) between batches pigs an intervention measure that has potential reduce transmission within farms. In this study, two pig finisher buildings each 10 positive...
Abstract Oak decline is a complex disorder caused by multiple stressors. Although declines have been observed across Europe since 1700, there still lot of uncertainty around the cause, and therefore appropriate management techniques. Using literature from European oak ecosystems, this review perspective discusses key stressors associated with in Quercus robur L. Q. petraea (Matt.) Liebl. newly described acute breaking out United Kingdom (and beyond), view to identifying important evidence...
Within the European Union, Salmonella is frequently reported in food and feed products. A major route of transmission upon contact with contaminated surfaces. In nature, bacteria such as are often encountered biofilms, where they protected against antibiotics disinfectants. Therefore, removal inactivation biofilms essential to ensure hygienic conditions. Currently, recommendations for disinfectant usage based on results efficacy testing planktonic bacteria. There no biofilm-specific...
Fluoroquinolones are a widely used group of antimicrobials in both human and animal medicine, with ciprofloxacin being critically important fluoroquinolone for serious infections. The present study reports on 1-year survey the presence ciprofloxacin-resistant Escherichia coli turkeys from Great Britain. Boot swabs were taken 442 turkey flocks comprised 125 breeding 317 meat 337 different farms over period (2006 to 2007). CHROMagar ECC containing 1 mg/l was obtain isolates. Isolates tested...
Salmonella can enter hatcheries via contaminated eggs and other breaches of biosecurity. The study examined the prevalence distribution in commercial assessed effects providing advice on control. Intensive swab sampling was performed throughout 23 broiler Great Britain (GB). Swabs were cultured using a modified ISO6579:2017 method. After each visit, tailored biosecurity cleaning disinfection procedures provided to hatchery managers. Repeat carried out 10 hatcheries. ranged between 0% 33.5%,...
Four models are presented investigating risks present on Great Britain (GB) turkey farms in breeding and fattening flocks for ciprofloxacin cephalosporin resistance. Risk factors resistance were sourcing of feed from national compounders, antimicrobial use the flock evidence mice. Disinfection floors walls at depopulation, older division with partitions reduced risk. In holding over 10,000 birds, administration fluoroquinolones within last year horses neighbouring farm all increased risk,...
This study compared a novel non-formaldehyde combination product developed for pathogen control in animal feed Finio (A), with panel of three commonly used organic acid additive products: Fysal (B), SalCURB K2 (C) and Salgard (D). Products were evaluated their ability to reduce Salmonella Typhimurium DT104 avian pathogenic Escherichia coli poultry feed. A commercial layer-hen mash was treated each then mixed previously contaminated (via inoculated meat bone meal) either or E. coli. After 24...
Organic acid products are widely used in the UK poultry industry as feed or water additives. Claims for Salmonella control made some of these products, but there few studies comparing anti-Salmonella effect various tests that reflect field application. The present examined effects 13 commercial blends (four and nine products) on Enteritidis Typhimurium strains. Initial screening, nutrient broth, all with strains revealed little variation between respect maximum inhibitory bactericidal...
Abstract Salmonella prevalence in UK pigs is amongst the highest Europe, highlighting need to investigate pig farms which have managed maintain a low seroprevalence. A total of 19 that had consistently (<10%) seroprevalence over 4 years (named Platinum farms) were compared against 38 randomly selected Control farms, chosen match same distribution production types and geographical farms. Each farm was visited floor faeces environmental samples collected. It shown significantly higher...
1. High standards of biosecurity are known to reduce the risk disease outbreaks; however, uptake advice and implementation measures dependent on many factors.2. This study assessed targeted by 60 laying hen farms provided during audit visits. Advice was as bullet point cards focusing specific areas identified benefitting from improvement. These covered site entrance, tidiness, vaccination, boot hygiene, hand house rodent control, fly red mite control cleaning disinfection between flocks....
Salmonella Enteritidis (SE) and, to a lesser extent, Typhimurium (ST) are associated with egg-related outbreaks in people. Recently, monophasic strains of ST (mST; lacking one phase the flagellar antigen) have been described, and they officially classified as variants thus may contribute human exposure contaminated eggs. Currently used vaccination programmes licensed for use against biphasic ST, their efficacy mST has not yet investigated. In this study, effectiveness four currently UK...
In the European Union, statutory control of Salmonella is in place chicken and turkey sectors, but not duck sector. this study, 14 Salmonella-positive farms were sampled before after cleaning disinfection, once houses had been restocked with a new flock. The disinfection programmes used subdivided into two main categories: ones which final formaldehyde step was included (1) it (2). Several types samples collected during faecal those more frequently positive (62% for comparison to 2-23% from...

There has been a rapid rise in the prevalence of cases monophasic Salmonella Typhimurium (mST) both humans and farm animals, it found pigs, cattle poultry. It is therefore vital to have good understanding how efficiently detect infected farms. The objective this project was determine sample type sensitivity detection groups animals on pig (breeder, grower finisher sites) (beef dairy) farms, using data collected from study investigating farms that were positive for mST, explore any variation...
Abstract Mapping polyclonal antibody responses to infectious diseases identify individual epitopes has the potential underpin development of novel serological assays and vaccines. Here, phage-peptide library panning coupled with screening using next generation sequencing was used map bacterial infections. In first instance, pigs experimentally infected Salmonella enterica serovar Typhimurium investigated. IgG samples from twelve were probed in parallel phage binding compared that equivalent...
Salmonella enterica is a causative pathogen of Salmonellosis, zoonosis causing global disease and financial losses every year. Pigs may be carriers contribute to the spread humans food products. persist as biofilms. Biofilms are bacterial aggregates embedded in self-produced matrix known withstand disinfectants. We studied effect glutaraldehyde peracetic acid, two active substances frequently used disinfectant formulations pig industry, on representative biofilm-residing wild-type collected...
In 2010, 81 confirmed cases of Salmonella Typhimurium DT8 were reported across England and Northern Ireland - an increase 26% from 2009 41% since 2008. Five hospitalized one death reported, with a strong association found between the consumption duck eggs. Once present on farms, may become persistent can survive for long periods time in residual organic matter, increasing risk infection follow-on flocks if cleaning disinfection is not carried out effectively. The aim this study was to...
Egg-related outbreaks of salmonellosis are a significant health concern. Although Salmonella Enteritidis (SE) is the major egg-associated serotype, Typhimurium (ST) can also infect hen's reproductive tract and contaminate eggs. Recently, monophasic aphasic variants ST have been reported with increased frequency in Europe, isolation these from laying flocks triggers same legislative restrictions associated biphasic strains. However, little known about colonization, invasiveness persistence...
Abstract Serological surveillance and vaccination are important strategies for controlling infectious diseases of food production animals. However, the compatibility these is limited by a lack assays capable differentiating infected from vaccinated animals (DIVA tests) established killed or attenuated vaccines. Here, we used next generation phage-display (NGPD) 2-proportion Z score analysis to identify peptides that were preferentially bound IgY chickens with Salmonella Typhimurium S ....
Salmonella-contaminated poultry house dust plus 10 g chicken faeces inoculated with Salmonella Enteritidis and then frozen for storage transport were used as candidate external quality assurance test samples. Variations in sample preparation, culture examined initially. This indicated that, within modest limits, the age of inoculating did not affect detection, nor swirling pre-enrichment or extending its duration. Under optimal conditions preparation storage, numbers 70 colony-forming units...
