Lethal salmonella outbreak

Salmonella London - Arabstoday One person has died and at least 50 more have fallen ill from salmonella poisoning which may be linked to watermelons imported from Brazil. The outbreak, which began in December, is believed to involve packs of ready-to-eat sliced watermelon. Health chiefs say the public can protect themselves by washing all types of fruit and vegetables. However many are unlikely to wash packs of ready-to-eat fruit, which have become enormously popular and are often sold as a healthy lunchtime snack. Seventy per cent of the victims are female and include a six-month-old baby and pensioners. The one British fatality was suffering from a number of other underlying health problems. Details of the outbreak – involving the Salmonella Newport form of the bug –  were revealed by the Health Protection Agency, which is investigating the source alongside the Food Standards Agency. Thirty five of the cases were in the UK, with 26 in England, five in Scotland, three in Wales and one in Northern Ireland. The same strain of the bug has been identified in a further five cases in the Republic of Ireland and 15 in Germany. The presence of salmonella was first identified by HPA scientists carrying out routine sampling of a range of foods for the presence of listeria. The watermelon sampled was imported from Brazil and between ten and 15 of the victims reported eating the fruit in the two to three days before they fell ill. However the HPA stressed it cannot be certain the victims ate watermelon from Brazil and it is too soon to identify the source. Brazil is the largest supplier of imported watermelons sold in the UK accounting for around 12 per cent of the total, which equates to around 6,100 tonnes. Virtually all the major supermarkets import them from Brazil at this time of year. Last night Tesco, Sainsbury’s, Morrisons, Waitrose and the Co-op insisted their watermelons were not affected. Dr Bob Adak, head of gastrointestinal diseases at the HPA, said: ‘Early indications suggest that a number of people became unwell after eating watermelon. ‘It’s important to remember the risk of becoming unwell after eating watermelon is very low. These cases only represent a very small proportion of total consumption. ‘It is always advisable to wash fruits and vegetables – including watermelon – before consumption to reduce the risk of illness.’ Dr Paul Wigley, an expert in food borne diseases based at the University of Liverpool, said: ‘As Salmonella Newport is often associated with cattle or horses, contamination from animal manure used as fertilizer is a potential source. ‘As this appears to be a problem in pre-sliced melon, contamination on the surface could be transferred to the flesh when cut, or contaminated water may have been used in washing the melons. ‘Fruit and vegetables are not the main source of infection which is usually meat or unpasteurised dairy products, but they can be contaminated with salmonella in production or processing.’ Alison Gleadle, director of food safety at the FSA, said: ‘We are working closely with the European Commission, other countries, local authorities and the food industry, to investigate further.’
