**Health Officials Urge Vigilance as Foodborne Illnesses Pose Greater Risks to Children During Summer**


As the summer holidays begin in earnest across the UK, health experts are cautioning parents to remain vigilant over a trio of foodborne infections that can quickly escalate into serious health issues in young children. The UK Health Security Agency (UKHSA) has issued fresh guidance, as warmer weather and increased outdoor activities often correlate with a rise in certain bacterial illnesses.

The agency warns specifically against three types of bacteria that become more common during summer: Salmonella, Campylobacter, and Shiga toxin-producing E. coli (STEC). These bacteria are typically contracted through the consumption of contaminated food or water, but can also spread through contact with animals or exposure to certain environments. Early symptoms in children may emerge as stomach cramps, fever, and diarrhoea – with the latter sometimes appearing bloody.
Parents and caregivers are being reminded of the importance of recognising these initial symptoms promptly. If a child develops severe or bloody diarrhoea, exhibits signs of dehydration, or the illness seems prolonged or worsening, the UKHSA strongly recommends contacting a GP or NHS 111 for advice and assessment.
**STEC Among the Most Contagious Threats**
STEC, short for Shiga toxin-producing E. coli, is deemed particularly infectious and worrisome. While cattle are the most common source, the bacteria can find its way into families and childcare settings through contaminated food, water, or direct animal contact. Outbreaks have also been linked to swimming in untreated water. Most cases of STEC present with diarrhoea, stomach cramps, and fever, usually subsiding within two weeks. However, in roughly 10% of cases—most frequently in children and the elderly—the infection can trigger haemolytic uraemic syndrome. This potentially life-threatening complication can severely damage the kidneys and ultimately result in kidney failure.
Adults, on the other hand, may be susceptible to thrombotic thrombocytopaenic purpura, a rare disorder that involves the formation of small clots throughout the body. Though initial symptoms may appear flu-like, this condition can rapidly become a medical emergency. There are currently no specific treatments for STEC, with care focused on managing symptoms and preventing dehydration.
**Campylobacter: A Common Culprit**
Among the leading causes of bacterial gastroenteritis in the UK, Campylobacter is responsible for a significant proportion of stomach upsets every year. According to the World Health Organisation, up to one in ten individuals may be affected globally on an annual basis. The infection is typically contracted through undercooked poultry, raw milk, or untreated water—which means summer barbecues and trips to rural areas can heighten exposure risk.
Symptoms often develop several days after infection—sometimes up to ten days—and linger for about six days. Common signs include abdominal pain, fever, diarrhoea, headache, nausea, and vomiting. Though serious complications such as pancreatitis and reactive arthritis are rare, they can occur, highlighting the importance of rapid medical attention if symptoms worsen.
**Salmonella: Persistent Food Safety Hazard**
Salmonella infection, another common foodborne risk, is particularly associated with consumption of animal products such as eggs, poultry, and unpasteurised milk. However, the bacteria can also be carried by a variety of animals, including reptiles and household pets. The familiar symptoms of infection—diarrhoea, stomach pain, nausea, vomiting, and fever—typically develop within 12 to 72 hours of exposure.
Illness generally resolves within a week; however, parents should remain alert if their child’s symptoms persist beyond this period or appear severe, especially as complications can be more serious in very young children, the elderly, or those with weakened immune systems.
**Key Preventive Measures**
Health authorities stress that many cases of foodborne illness, while common, are preventable. Thorough handwashing after handling animals or raw foods, ensuring meats are properly cooked, and avoiding unpasteurised dairy products are simple but effective steps. Additionally, parents should be wary of water sources—encourage children not to swallow swimming water, particularly in untreated ponds or lakes.
**Rising Cases Prompt Public Health Reminder**
Increased travel, picnics, and outdoor gatherings during the school holidays offer more opportunities for bacteria to spread. Health experts acknowledge that most bouts of stomach upset in children are mild and resolve without incident, but the risk of more severe outcomes justifies this renewed call for public awareness.
**Seeking Help: When to Act**
The UKHSA advises that medical input should be sought without delay if a child develops severe or bloody diarrhoea, signs of dehydration such as decreased urination or drowsiness, or if the illness continues for an unusually long period. Early intervention can be critical in preventing complications, especially in vulnerable children.
For further information, parents are encouraged to consult trusted health resources, including the NHS website and official government guidance for the latest updates on foodborne illness prevention and treatment.
With summer in full swing, the message from public health specialists is clear: an informed and cautious approach is the best way to keep children safe and healthy as they enjoy the season’s activities.
