Summer heat raises risk of intestinal infections, doctors warn

As temperatures climb, health experts are warning that summer heat creates ideal conditions for the spread of intestinal infections, particularly through cream-based foods such as cakes, pastries, and ice cream. Specialists at the Heratsi Research Center note that improper storage, poor hygiene, and contaminated ingredients can quickly turn these products into breeding grounds for harmful bacteria.

Among the most common culprits are Salmonella, often linked to raw eggs; Staphylococcus aureus, which can be transmitted by infected food handlers; E. coli, spread through dirty hands or unsafe water; and Campylobacter, found in unpasteurized dairy and undercooked meat. Symptoms typically include diarrhea, abdominal pain, fever, nausea, vomiting, and fatigue.

Doctors advise consumers to reduce risk by:

• Choosing refrigerated products stored at 2C–6C.

• Checking expiration dates before purchase.

• Avoiding uncertified vendors such as street stalls.

• Keeping foods cold until consumption.

• Skipping cream-based snacks during long trips.

One of the most dangerous complications of intestinal infections is dehydration, which can be life-threatening in children, the elderly, and those with chronic illnesses. Warning signs include dry mouth, dark urine, dizziness, fatigue, and rapid heartbeat. Severe cases may require intravenous fluids.

To prevent dehydration, experts recommend drinking six to eight glasses of water daily — more in hot weather — and consuming hydrating foods such as watermelon, cucumbers, and soups. Electrolyte solutions are advised for those experiencing diarrhea or vomiting. Elderly individuals, who may not feel thirst as strongly, should be reminded to drink regularly.
