The European Union summary report on surveillance for the presence of transmissible spongiform encephalopathies (TSEs) in 2017.

ABSTRACT: This report presents the results of surveillance on transmissible spongiform encephalopathies (TSEs) in bovine animals, sheep, goats, cervids and other animal species, as well as genotyping in sheep, carried out in 2017 in the European Union (EU) according to Regulation (EC) 999/2001, and in Iceland, Norway and Switzerland. In total, 1,312,714 cattle were tested by the 28 EU Member States (MSs) which is a decrease of 3% compared with 2016; 18,526 were tested by the three non-MSs. For the first time since bovine spongiform encephalopathy (BSE) has been reported, no cases of classical BSE were reported in 2017. Six atypical BSE cases were reported by three different MSs: Spain 1 H-BSE/2 L-BSE; France 1 H-BSE/1 L-BSE; and Ireland 1 L-BSE. Over the year, 314,547 sheep and 117,268 goats were tested in the EU. In sheep, 933 cases of scrapie were reported: 839 classical and unknown (145 index cases) by eight MSs and 94 atypical (89 index cases) by 13 MSs. Fourteen ovine scrapie cases were reported by Iceland and Norway. Of all classical scrapie cases, 98.2% occurred in sheep with genotypes of susceptible groups. The genotyping of a random sample in 21 MSs showed that 26.5% of the genotyped sheep carried genotypes of the susceptible groups. In goats 567 cases of scrapie were reported: 558 classical (42 index cases) by seven MSs and nine atypical (seven index cases) by five MSs. In total, 3,585 cervids were tested for TSE by ten MSs, mostly by Romania. All results were negative. Eleven cases of chronic wasting disease (CWD) cases were reported in cervids by Norway: nine wild reindeer, one moose and, for the first time ever, one red deer. In total, 185 animals from five species other than cattle, small ruminants and cervids were tested by three MSs, with negative results.

Project description:BackgroundAs there is limited information about the clinical signs of BSE and scrapie in goats, studies were conducted to describe the clinical progression of scrapie and BSE in goats and to evaluate a short clinical protocol for its use in detecting scrapie-affected goats in two herds with previously confirmed scrapie cases. Clinical assessments were carried out in five goats intracerebrally infected with the BSE agent as well as five reported scrapie suspects and 346 goats subject to cull from the two herds, 24 of which were retained for further monitoring. The brain and selected lymphoid tissue were examined by postmortem tests for disease confirmation.ResultsThe sensitivity and specificity of the short clinical protocol in detecting a scrapie case in the scrapie-affected herds was 3.9% and 99.6%, respectively, based on the presence of tremor, positive scratch test, extensive hair loss, ataxia and absent menace response. All BSE- and scrapie-affected goats displayed abnormalities in sensation (over-reactivity to external stimuli, startle responses, pruritus, absent menace response) and movement (ataxia, tremor, postural deficits) at an advanced clinical stage but the first detectable sign associated with scrapie or BSE could vary between animals. Signs of pruritus were not always present despite similar prion protein genotypes. Clinical signs of scrapie were also displayed by two scrapie cases that presented with detectable disease-associated prion protein only in lymphoid tissues.ConclusionsBSE and scrapie may present as pruritic and non-pruritic forms in goats. Signs assessed for the clinical diagnosis of scrapie or BSE in goats should include postural and gait abnormalities, pruritus and visual impairment. However, many scrapie cases will be missed if detection is solely based on the display of clinical signs. PrPd accumulation in the brain appeared to be related to the severity of clinical disease but not to the display of individual neurological signs.

Project description:This report of the European Food Safety Authority and the European Centre for Disease Prevention and Control presents the results of zoonoses monitoring activities carried out in 2017 in 37 European countries (28 Member States (MS) and nine non-MS). Campylobacteriosis was the commonest reported zoonosis and its EU trend for confirmed human cases increasing since 2008 stabilised during 2013-2017. The decreasing EU trend for confirmed human salmonellosis cases since 2008 ended during 2013-2017, and the proportion of human Salmonella Enteritidis cases increased, mostly due to one MS starting to report serotype data. Sixteen MS met all Salmonella reduction targets for poultry, whereas 12 MS failed meeting at least one. The EU flock prevalence of target Salmonella serovars in breeding hens, laying hens, broilers and fattening turkeys decreased or remained stable compared to 2016, and slightly increased in breeding turkeys. Salmonella results on pig carcases and target Salmonella serovar results for poultry from competent authorities tended to be generally higher compared to those from food business operators. The notification rate of human listeriosis further increased in 2017, despite Listeria seldom exceeding the EU food safety limit in ready-to-eat food. The decreasing EU trend for confirmed yersiniosis cases since 2008 stabilised during 2013-2017. The number of confirmed shiga toxin-producing Escherichia coli (STEC) infections in humans was stable. A total of 5,079 food-borne (including waterborne) outbreaks were reported. Salmonella was the commonest detected agent with S. Enteritidis causing one out of seven outbreaks, followed by other bacteria, bacterial toxins and viruses. The agent was unknown in 37.6% of all outbreaks. Salmonella in eggs and Salmonella in meat and meat products were the highest risk agent/food pairs. The report further summarises trends and sources for bovine tuberculosis, Brucella, Trichinella, Echinococcus, Toxoplasma, rabies, Coxiella burnetii (Q fever), West Nile virus and tularaemia.

Project description:The data on antimicrobial resistance in zoonotic and indicator bacteria in 2017, submitted by 28 EU Member States (MSs), were jointly analysed by EFSA and ECDC. Resistance in zoonotic Salmonella and Campylobacter from humans, animals and food, and resistance in indicator Escherichia coli as well as meticillin-resistant Staphylococcus aureus in animals and food were addressed, and temporal trends assessed. 'Microbiological' resistance was assessed using epidemiological cut-off (ECOFF) values; for some countries, qualitative data on human isolates were interpreted in a way which corresponds closely to the ECOFF-defined 'microbiological' resistance. In Salmonella from humans, as well as in Salmonella and E. coli isolates from fattening pigs and calves of less than 1 year of age, high proportions of isolates were resistant to ampicillin, sulfonamides and tetracyclines, whereas resistance to third-generation cephalosporins was uncommon. Varying occurrence/prevalence rates of presumptive extended-spectrum beta-lactamase (ESBL)/AmpC producers in Salmonella and E. coli monitored in meat (pork and beef), fattening pigs and calves, and Salmonella monitored in humans, were observed between countries. Carbapenemase-producing E. coli were detected in one single sample from fattening pigs in one MS. Resistance to colistin was observed at low levels in Salmonella and E. coli from fattening pigs and calves and meat thereof and in Salmonella from humans. In Campylobacter from humans, high to extremely high proportions of isolates were resistant to ciprofloxacin and tetracyclines, particularly in Campylobacter coli. In five countries, high to very high proportions of C. coli from humans were resistant also to erythromycin, leaving few options for treatment of severe Campylobacter infections. High resistance to ciprofloxacin and tetracyclines was observed in C. coli isolates from fattening pigs, whereas much lower levels were recorded for erythromycin. Combined resistance to critically important antimicrobials in both human and animal isolates was generally uncommon but very high to extremely high multidrug resistance levels were observed in S. Typhimurium and its monophasic variant in both humans and animals. S. Kentucky from humans exhibited high-level resistance to ciprofloxacin, in addition to a high prevalence of ESBL.

Project description:Data on antimicrobial resistance (AMR) in zoonotic and indicator bacteria from humans, animals and food are collected annually by the EU Member States (MSs), jointly analysed by EFSA and ECDC and reported in a yearly EU Summary Report. The annual monitoring of AMR in animals and food within the EU is targeted at selected animal species corresponding to the reporting year. The 2017 monitoring specifically focussed on pigs and calves under 1 year of age, as well as their derived carcases/meat, while the monitoring performed in 2018 specifically focussed on poultry and their derived carcases/meat. Monitoring and reporting of AMR in 2017/2018 included data regarding Salmonella, Campylobacter and indicator Escherichia coli isolates, as well as data obtained from the specific monitoring of ESBL-/AmpC-/carbapenemase-producing E. coli isolates. Additionally, some MSs reported voluntary data on the occurrence of meticillin-resistant Staphylococcus aureus in animals and food, with some countries also providing data on antimicrobial susceptibility. This report provides, for the first time, an overview of the main findings of the 2017/2018 harmonised AMR monitoring in the main food-producing animal populations monitored, in related carcase/meat samples and in humans. Where available, data monitoring obtained from pigs, calves/cattle, broilers, laying hens and turkeys, as well as from carcase/meat samples and humans were combined and compared at the EU level, with particular emphasis on multiple drug resistance, complete susceptibility and combined resistance patterns to critically important antimicrobials, as well as Salmonella and E. coli isolates exhibiting presumptive ESBL-/AmpC-/carbapenemase-producing phenotypes. The outcome indicators for AMR in food-producing animals, such as complete susceptibility to the harmonised panel of antimicrobials in E. coli and the prevalence of ESBL-/AmpC-producing E. coli have been also specifically analysed over the period 2014-2018.
