The qualified presumption of safety (QPS) approach was developed to provide a regularly updated generic pre-evaluation the biological agents, intended for addition food or feed, support work EFSA's Scientific Panels. It is based on an assessment published data each agent, with respect its taxonomic identity, body knowledge, concerns and antimicrobial resistance.

The qualified presumption of safety (QPS) was developed to provide a pre-assessment within EFSA for microorganisms. Strains belonging QPS taxonomic units (TUs) still require an assessment based on specific data package, but status facilitates fast track evaluation. TUs are unambiguously defined biological agents assessed the body knowledge, their and end use. Safety concerns are, where possible, be confirmed at strain or product level, reflected as 'qualifications'. Qualifications need...
The provisional molecular approach, proposed by EFSA in 2013, for the pathogenicity assessment of Shiga toxin-producing Escherichia coli (STEC) has been reviewed.Analysis confirmed reported human STEC infections EU/EEA (2012-2017) demonstrated that isolates positive any toxin (Stx) subtypes (and encoding stx gene subtypes) may be associated with severe illness (defined as bloody diarrhoea (BD), haemolytic uraemic syndrome (HUS) and/or hospitalisation).Although strains stx2a showed highest...
The role of food-producing environments in the emergence and spread antimicrobial resistance (AMR) EU plant-based food production, terrestrial animals (poultry, cattle pigs) aquaculture was assessed. Among various sources transmission routes identified, fertilisers faecal origin, irrigation surface water for were considered major importance. For animal potential consist feed, humans, water, air/dust, soil, wildlife, rodents, arthropods equipment. those, evidence found introduction with feed...
An increase in confirmed human salmonellosis cases the EU after 2014 triggered investigation of contributory factors and control options poultry production. Reconsideration five current target serovars for breeding hens showed that there is justification retaining Salmonella Enteritidis, Typhimurium (including monophasic variants) Infantis, while Virchow Hadar could be replaced by Kentucky either Heidelberg, Thompson or a variable serovar national prevalence targets. However, incorporates...
The qualified presumption of safety (QPS) approach was developed to provide a generic pre-evaluation the biological agents.

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...

The qualified presumption of safety (QPS) process was developed to provide a assessment approach for microorganisms intended use in food or feed chains. QPS is based on an published data each taxonomic unit (TU), with respect its identity, the body relevant knowledge and concerns. Safety concerns identified TU are, where possible, confirmed at species/strain product level reflected by 'qualifications'. In period covered this Statement, no new information found that would change status...
Water used in post-harvest handling and processing operations is an important risk factor for microbiological cross-contamination of fruits, vegetables herbs (FVH). Industrial data indicated that the fresh-whole FVH sector characterised by very variable operational cycle duration (between 8 900 h), large product volumes (e.g. more than 6000 tonnes) process water at 2.8-25.0°C. Intervention strategies were based on disinfection treatments, mostly using chlorine-based disinfectants....
A dynamic mass balance model was developed to simulate contamination dynamics in the process water of fresh and frozen fruits, vegetables herbs (ffFVH) during processing handling operations. The relates flux product a wash tank number microbial cells released water, inactivated by disinfectant or transferred from back product. Critical variables describing are: (i) chemical oxygen demand (COD), as an indicator concentration organic matter; (ii) free chlorine (FC) particularly its...
Abstract Microsatellites are promising genetic markers for studying the demographic structure and phylogenetic history of populations. We present theoretical arguments indicating that usefulness microsatellite data these purposes may be limited to a short time perspective relatively small The evolution selectively neutral is governed by interaction mutation random drift. Mutation pressure has inherent tendency shift different populations same distribution alleles. Hence, homogenizing force,...
SUMMARY We estimated the true incidence of campylobacteriosis and salmonellosis in European Union (EU) 2009. The estimate was based on disease risks returning Swedish travellers, averaged over years 2005–2009, anchored to a Dutch population-based study aetiology gastroenteritis. For 27 EU member states about 9·2 (95% CI 2·8–23) million cases, while 6·2 1·0–19) cases. Only 1/47 14–117) cases one 1/58 9–172) were reported EU. rate varied between 30 13 500/100 000 population significantly...
As a major foodborne pathogen, Campylobacter jejuni receives much attention in quantitative risk assessment. To date, all dose-response assessments have been based on single human feeding study which unfortunately provides incomplete and possibly biased information the relation. An incident at dairy farm, where several children from school class became ill as result of drinking raw milk contaminated with C. jejuni, appeared to show very clear relation between amount consumed attack rate....
Parasites are important food-borne pathogens.Their complex lifecycles, varied transmission routes, and prolonged periods between infection symptoms mean that the public health burden relative importance of different routes often difficult to assess.Furthermore, there challenges in detection diagnostics, variations reporting.A Europe-focused ranking exercise, using multicriteria decision analysis, identified potentially parasites importance, currently not routinely controlled food.These...
This Opinion considers the application of whole genome sequencing (WGS) and metagenomics for outbreak investigation, source attribution risk assessment food-borne pathogens. WGS offers highest level bacterial strain discrimination investigation source-attribution as well potential more precise hazard identification, thereby facilitating targeted management. improves linking sporadic cases associated with different food products geographical regions to a point can facilitate epidemiological...
The 2011 EFSA opinion on Campylobacter was updated using more recent scientific data. relative risk reduction in EU human campylobacteriosis attributable to broiler meat estimated for on-farm control options Population Attributable Fractions (PAF) interventions that reduce flock prevalence, updating the modelling approach caecal concentrations and reviewing literature. According PAF analyses calculated six options, mean reductions could be achieved by adoption of each these individually are...
Food legislation in the European Union and elsewhere includes both hazard- risk-based approaches for ensuring safety. In hazard-based approaches, simply presence of a potentially harmful agent at detectable level food is used as basis and/or risk management action. Risk-based allow consideration exposure assessing whether there may be unacceptable risks to health. The advantages disadvantages safety chemicals, allergens, ingredients microorganisms were explored an ILSI Europe workshop. It...

High-pressure processing (HPP) is a non-thermal treatment in which, for microbial inactivation, foods are subjected to isostatic pressures (P) of 400-600 MPa with common holding times (t) from 1.5 6 min. The main factors that influence the efficacy (log10 reduction vegetative microorganisms) HPP when applied foodstuffs intrinsic (e.g. water activity and pH), extrinsic (P t) microorganism-related (type, taxonomic unit, strain physiological state).
