This paper describes the current situation of animal tuberculosis in Portugal, reviewing the accomplishments and constraints of the 2001-2009 period. Notwithstanding the substantial progress achieved with the implementation of a comprehensive test and cull scheme, notification, postmortem inspection and surveillance at slaughterhouses, herd and animal prevalence have unexpectedly increased in 2...

Toxoplasma gondii has frequently been named as one of the most important foodborne pathogens, in terms of its impact on human health. EFSA advised to include serological testing of pigs on T. gondii infections and audits of pig farms on risk factors for T. gondii infection (EFSA, 2011). In order to generate knowledge about the epidemiology and prevalence of T. gondii infections in pig herds we ...

Foot-pad dermatitis is a major welfare concern of broilers caused by ammonia irritation from the bedding material. In Denmark, an action plan to control the condition was implemented in 2002 with monitoring through a foot scoring system at slaughter and with predefined limits that trigger sanctions. The objective of the present study was to study time trends and to identify predisposing factors...

The relation between occupational exposure to cattle and prevalence of antibodies against Pasteurella multocida was evaluated in 680 workers. Three groups of exposed workers in abattoirs and slaughterhouses (S), in industrial breeding (I), and in traditional breeding (T) were compared with control workers not exposed to cattle or chicken (C). The prevalence of antibodies against capsular antige...

Control or eradication of Taenia solium cysticercosis has been achieved to date only in Europe and North America. Significant improvements in sanitary conditions and developing functional slaughterhouse control systems were primarily responsible for control in these regions. Conversely, in endemic areas of developing countries control is limited by economic and sanitary conditions: the life cyc...

This paper presents a quantitative risk assessment method based on the portrayal of risks using scenario trees, the translation of evidence into probability curves and the aggregation of scenarios using Latin Hypercube simulation. An example of a quantitative risk assessment on the importation of swine for slaughter illustrates the interpretation of evidence of two swine disease risks: pseudora...

Uzbekistan is endemic of cystic echinococcosis (CE). In order to estimate endemicity of CE, we collected data from emergency surgery due to CE in 2002-2010 and also investigated the prevalence of hydatid cysts in the liver and lungs of sheep at an abattoir in Uzbekistan from July 2009 to June 2010. In 14 emergency hospitals, 8,014 patients received surgical removal or drainage of CE during 2002...

The Danish pork Salmonella control program was initiated in 1993 in response to a prominent pork-related outbreak in Copenhagen. It involved improved efforts at slaughter hygiene (postharvest) and on-farm (preharvest) surveillance and control. After 10 years, 95 million Euros, significant reductions in seropositive herds, Salmonella positive carcasses, and pork-attributable human cases (PAHC), ...

Anaerobic digestion is the most suitable option for the treatment of high strength organic effluents. The presence of biodegradable components in the effluents coupled with the advantages of anaerobic process over other treatment methods makes it an attractive option. This paper reviews the suitability and the status of development of anaerobic reactors for the digestion of selected organic eff...
