Research on the prevalence of Salmonella and Campylobacter in Icelandic chicken products on the consumer market 

With the adoption of most of the food rules and EU food legislation (178/2002 and 102/2010), it is clear that the import of fresh meat products to Iceland could become a reality, but so far the government has banned such imports altogether. In this context, there is a need to obtain data on the safety of Icelandic products on the market with regard to microbial contamination. Extensive data are available on the frequency of Salmonella and Campylobacter in poultry farming in Iceland and at slaughter in recent years, but there has been a lack of information on the state of affairs in the consumer market. The aim of this study was therefore to investigate the frequency of these pathogens in Icelandic fresh chicken products on the market. A total of 537 samples were taken over a 12-month period from May 2012 to April 2013 from the country's three largest producers. 183 packs of whole chickens, 177 packs of breasts and 177 packs of wings were examined. All samples in the study were negative for both Salmonella and Campylobacter. It is therefore clear that the situation in these countries is very good and as good or better than what is happening in other countries.

With the adoption of the main parts of the EU food legislation (178/2002 and 102/2010) it is evident that import of fresh meat and poultry could be possible even though at present it is still prohibited by the Icelandic government. In this respect it is advisable to keep data on the safety of Icelandic products already on the market for current reference. Extensive data are available of the frequency of Salmonella and Campylobacter at the breeding and slaughtering steps in the poultry supply chain in Iceland but no systematic data collection has been done at the retail level in recent years. The aim of this study was therefore to estimate the frequency of contamination of the above mentioned pathogens in consumer packs of Icelandic poultry production. A total of 537 samples were collected in a 12 month period from May 2012 to April 2013 from the three largest domestic producers. Total of 183 packs of whole chicken were analyzed, 177 packs of fillets and 177 packs of wing cuts. All samples measured negative both for Salmonella and Campylobacter. It is therefore confirmed that the monitoring scheme and intervention policy in Icelandic poultry production is effective and that the status of contamination of these pathogens in fresh retail poultry packs is as good as, or better than in other EU states.

24-hour detection of undesirable microbes in food / 24-hour detection of undesirable microbes in food

The aim of the project was to develop and establish methods for rapid detection of undesirable bacteria in agricultural and marine products as well as other foods. With traditional methods as used today, results are obtained after 3 and up to 7 days, but with the methods developed in this project, it is possible to get results in a few hours or within 24 hours. The method is based on real-time PCR methodology and specific amplification of the genetic material of pathogenic bacteria and other undesirable bacteria. Diagnostic methods have been developed for major pathogens (Salmonella, Campylobacter, Listeria monocytogenes, Vibrio parahaemolyticus) in milk, meat and fish products as well as for specific spoilage bacteria in food. The results of the project will improve services to the food industry in Iceland by detecting unwanted microorganisms much earlier so that it is possible to intervene in production processes and thereby increase consumer safety in agricultural and fish products.

The aim of this project was to develop and set up new methods for rapid identification of undesirable bacteria in food and feed. With today's conventional and accredited culture methods results can be expected after 3 and up to 7 days. With the new methods to be taken in use and was developed in this project, the time of diagnostic procedure will decrease to few hours or to one working day. The detection methods are based on real ‐ time PCR technology and a specific amplification of genetic material of the undesired bacteria. Diagnostic methods for the most common pathogens (Salmonella, Campylobacter, Listeria monocytogenes, Vibrio parahaemolyticus) in meat‐, milk and fish products were developed through as well as quantitative assays for the main spoilage bacteria in fish. The results of the project will be used to improve the service for the Icelandic food industry on the domestic‐ and overseas markets by having rapid diagnostic methods for bacterial contamination at hand.
