Two individuals have died and nearly 500 people have been infected with salmonella in the United Kingdom, according to health officials. The UK Health Security Agency (UKHSA) reported a significant increase in cases over the past month, with 259 confirmed infections and one death noted last week, bringing the total to 474 across three major outbreaks.
Investigations are ongoing, but health authorities believe imported eggs are the likely cause of the current crisis. The cases in the UK have primarily been linked to consumption at small cafes, restaurants, and takeaway businesses. Similar salmonella cases are also being reported in seven other European countries, including Austria, Belgium, Denmark, France, Germany, and the Netherlands, as public health officials work to pinpoint the exact origin.
While the UKHSA has identified a connection to imported eggs, Dutch health officials are investigating chicken products as a potential source. Salmonella infections can lead to severe symptoms such as stomach cramps, diarrhea, dehydration, blood poisoning, organ failure, and in rare cases, death. Vulnerable populations, including those over 65, pregnant women, and children under five, have been advised to avoid undercooked eggs when dining out.
More than a third of confirmed salmonella patients in Britain, ranging from infants to individuals as old as 92, have required hospitalization. In two instances, the infection spread from the gut into the bloodstream, a potentially life-threatening complication. Although most cases have emerged in recent weeks and months, some samples date back to August of the previous year. England has seen the majority of infections, with London and Yorkshire and the Humber being the most affected regions.
Despite the rising numbers, health officials maintain that the overall risk to the general public remains low. Hannah Charles, lead epidemiologist at UKHSA, stated that investigations are continuing in collaboration with the Food Standards Agency (FSA) and other public health bodies. She emphasized that while a link to imported eggs is indicated, the investigation is ongoing and further common sources will be explored if identified.
Professor Ian Young, chief safety adviser to the FSA, reiterated that thoroughly cooked eggs handled hygienically pose no food safety risk. Commercial hens supplying UK supermarkets are vaccinated against common salmonella strains, making an outbreak originating within Britain unlikely. Nevertheless, overall salmonella cases have been on an upward trend, with 10,406 recorded cases last year, marking a decade high.
Experts stress that salmonella should not be underestimated. When the bacteria, which can reside in the intestines of farm animals, breaches the gut wall and enters the bloodstream, it can lead to bacteraemia and serious complications. Individuals with weakened immune systems, young children, and the elderly are particularly at risk. One significant danger when salmonella enters the bloodstream is sepsis, a life-threatening condition where the body's immune response damages its own tissues and organs. Warning signs of sepsis can include confusion, severe shivering, breathlessness, reduced urine output, and changes in skin color. Sepsis requires immediate medical attention.
