Salmonella and pig production

serious about salmonella

The Food Standards Agency's strategic plan for 2005-2010 states our aim to achieve a further significant reduction in foodborne illness. This includes the more specific target of working with industry to achieve a 50% reduction in the numbers of pigs testing positive for salmonella at slaughter by 2010.

Salmonella – background

Salmonella can infect a wide range of animals, including pigs and humans. In pigs, weaners and growers are most commonly affected but symptoms are rarely seen, making infection difficult to recognise. It is these animals that risk spreading infection to the rest of the herd and may cause salmonella to enter the food chain.

Salmonella can cause salmonellosis in humans and is the second most common cause of food poisoning in the UK after campylobacter. Pork and pork products have been identified as a significant source of salmonella; therefore a reduction in the risk associated with these products will contribute to the protection of human health.

Abattoir surveys and ZAP

In 2003, Defra conducted a survey of animals at slaughter in Great Britain to determine the faecal carriage of pathogens, including salmonella in pigs. This study was similar in design to a previous abattoir survey conducted in 1999-2000. In the 1999-2000 survey salmonella was isolated from 23% of caecal samples taken from slaughter pigs and from 5.3% of carcasses. No improvement in levels of salmonella was found during the second survey in 2003, with 23.4% of caecal samples testing positive.

The results from these surveys indicate the need to take action. The industry recognised this need and the British Pig Executive (BPEX), together with the FSA and the Department for Environment, Food and Rural Affairs (Defra), launched the Zoonoses Action Plan (ZAP) in June 2002. The overall aim of this scheme is to monitor trends in the levels of salmonella on pig farms so that action can be taken to reduce the prevalence in pigs presented for slaughter. More details on the ZAP scheme, including annual reports and access to the ZAP database, can be accessed using the link at the bottom of this page.

Salmonella legislation

Following the introduction of the Food Hygiene Regulations in January 2006 (Regulation (EC) No. 852/2004, 853/2004, 854/2004), the responsibility for the production of safe food now lies with the food business operator. This responsibility extends from the primary producer up through the food chain to the consumer; a farm-to-fork approach.

The EU Zoonoses Regulation (EC) No 2160/2003 requires Member States to take effective measures to detect and control salmonellas in specified animal species, including pigs. An EU survey of pigs at slaughter is being carried out in the UK by Defra in partnership with the FSA, and will establish baseline data on the incidence of salmonella in the EU. The Agency has also provided funding for additional testing of caecum samples from the UK pigs. The outputs from these surveys are likely to form the basis of new legislation setting targets for the reduction of salmonella, to be achieved through the implementation of National Control Plans.

Back to basics campaign

The 'Serious about Salmonella' campaign was launched at a conference held in March 2007. It is targeted at those involved in the primary stage of the pig production chain, highlighting the need to be proactive in terms of on-farm biosecurity to control salmonella risk.

To promote the campaign's key messages, the Agency will run a number of regional workshops in early 2008 and will also be exhibiting at the Pig and Poultry Fair in May 2008. A copy of the advertisement and invitation for the regional workshops, as included in Pig World, can be found at the link at the bottom of this page.

Key Messages

Five key messages underpin the back to basics campaign, practising these can help control salmonella and help improve herd health generally; positively effecting general performance and productivity on the unit. These key messages are:
