Food safety impacts UK Salmonella cases
Food safety programmes, led by the British Lion egg scheme, has had a major contribution to improving public health due to the ‘remarkable decline’ in the instance of non-typhoidal Salmonella in the UK, a new research paper suggests.
The paper, titled ‘The “decline and fall” of non-typhoidal Salmonella in the United Kingdom’, has been published in Clinical Infectious Diseases and plots how the fall in incidences of Salmonella cases has coincided with the introduction of measures including an industry-led vaccination programme in broiler-breeder and laying poultry flocks.
The report states: “The incidence of Salmonella has been falling since 1997 and levels of Salmonella have fallen to pre‐epidemic levels and have stayed low. When Salmonella peaked in 1993 in the UK, over 18,000 laboratory‐confirmed cases of illness were recorded in national surveillance statistics, yet by 2010 this had fallen to just 459. Thus the decline in non‐typhoidal salmonellosis witnessed in the UK in recent years reflects this major contraction in reports of Salmonella.”
The report also found that, when analysing the source of outbreaks where raw shell eggs were involved, nearly 50% of foodborne Salmonella outbreaks occurred in the food service sector.
The report also notes that there have been national outbreaks of Salmonella linked to imported raw shell eggs in recent years. The report concludes that the relationship between vaccination programmes and the reduction in human disease is compelling and suggests that these programmes have made a major contribution to improving public health. “If success in public health is defined by illnesses averted then the story of Salmonella in the UK, which has come down and stayed down, is good news,” it says.
Andrew Joret, Chairman of the British Egg Industry Council, welcomed the report, saying: “This report further underlines the success of the British Lion Scheme in effectively eradicating Salmonella in UK eggs but it also highlights the importance of food manufacturers, retailers and caterers ensuring that they take extra care when purchasing eggs or egg products. This is even more important when you consider that illegally produced eggs, from non-compliant cages, are still being produced in the EU.
“The British Lion Code of Practice assures all those who specify Lion eggs and egg products that they can avoid these issues because they are using a product that is produced to the highest food safety standards.”
