1 MALTA The Report referred to in Article 9 of Directive 2003/ 99/ EC TRENDS AND SOURCES OF ZOONOSES AND ZOONOTIC AGENTS IN HUMANS, FOODSTUFFS, ANIMALS AND FEEDINGSTUFFS IN 2007 including information on foodborne outbreaks, antimicrobial resistance in zoonotic agents and some pathogenic microbiological agents

2 INFORMATION ON THE REPORTING AND MONITORING SYSTEM Country: Malta Reporting Year: 2007 Malta 2007

3 PREFACE This report is submitted to the European Commission in accordance with Article 9 of Council Directive 2003/ 99/ EC 1. The information has also been forwarded to the European Food Safety Authority (EFSA). The report contains information on trends and sources of zoonoses and zoonotic agents in Malta during the year The information covers the occurrence of these diseases and agents in humans, animals, foodstuffs and in some cases also in feedingstuffs. In addition the report includes data on antimicrobial resistance in some zoonotic agents and commensal bacteria as well as information on epidemiological investigations of foodborne outbreaks. Complementary data on susceptible animal populations in the country is also given. The information given covers both zoonoses that are important for the public health in the whole European Community as well as zoonoses, which are relevant on the basis of the national epidemiological situation. The report describes the monitoring systems in place and the prevention and control strategies applied in the country. For some zoonoses this monitoring is based on legal requirements laid down by the Community Legislation, while for the other zoonoses national approaches are applied. The report presents the results of the examinations carried out in the reporting year. A national evaluation of the epidemiological situation, with special reference to trends and sources of zoonotic infections, is given. Whenever possible, the relevance of findings in foodstuffs and animals to zoonoses cases in humans is evaluated. The information covered by this report is used in the annual Community Summary Report on zoonoses that is published each year by EFSA. 1 Directive 2003/ 99/ EC of the European Parliament and of the Council of 12 December 2003 on the monitoring of zoonoses and zoonotic agents, amending Decision 90/ 424/ EEC and repealing Council Directive 92/ 117/ EEC, OJ L 325, , p. 31 Malta 2007

10 2. INFORMATION ON SPECIFIC ZOONOSES AND ZOONOTIC AGENTS Zoonoses are diseases or infections, which are naturally transmissible directly or indirectly between animals and humans. Foodstuffs serve often as vehicles of zoonotic infections. Zoonotic agents cover viruses, bacteria, fungi, parasites or other biological entities that are likely to cause zoonoses. Malta

Salmonellosis in humans Reporting system in place for the human cases hopsital and private physician and laboratory mandatory notification system Case definition Clinical description: Clinical picture compatible with salmonellosis, e.g. diarrhoea, abdominal pain, nausea and sometimes vomiting. Laboratory Criteria for Diagnosis: Isolatin of Salmonella from a clinical specimen. Case definition: Probable: A laboratory confirmed isolate without clinical information or a case with clinical symptoms that has an epidemiological link. Confirmed case: A clinically compatible case that is laboratory confirmed. Diagnostic/ analytical methods used Isolation of Salmonella from a clinical specimen Notification system in place notification system as above History of the disease and/ or infection in the country Salmonellosis has been persistently prsent in Malta for many years. there has been a persistent decline since 1994 to about 15/ 10,000 population. National evaluation of the recent situation, the trends and sources of infection see above Relevance as zoonotic disease Still of relevance as the zoonotic disease causes a considerable amount of human illness Malta

20 Salmonella serovars and phagetype distribution The methods of collecting, isolating and testing of the Salmonella isolates are described in the chapters above respectively for each animal species, foodstuffs and humans. The serotype and phagetype distributions can be used to investigate the sources of the Salmonella infections in humans. Findings of same serovars and phagetypes in human cases and in foodstuffs or animals may indicate that the food category or animal species in question serves as a source of human infections. However as information is not available from all potential sources of infections, conclusions have to be drawn with caution. Malta

23 Antimicrobial resistance in Salmonella isolates Antimicrobial resistance is the ability of certain microorganisms to survive or grow in the presence of a given concentration of antimicrobial agent that usually would kill or inhibit the microorganism species in question.
