Experts warn of major summer threat: Food poisoning symptoms and how to protect yourself

Summer's warmer weather, ideal for outdoor gatherings, also brings a heightened risk of foodborne illnesses, experts are warning. Millions worldwide fall ill from food poisoning annually, with a notable increase in cases during the summer months. This surge is primarily attributed to higher temperatures, which create a more favorable environment for bacteria like E. coli, Salmonella, and Campylobacter to thrive and multiply.

When the temperatures are high, it can promote the growth and survival of bacteria.

Medical professionals explain that these pathogens flourish in warmer conditions, contaminating sensitive foods such as leafy greens, unpasteurized dairy products, undercooked meats, and deli items. The problem is exacerbated by increased outdoor activities like picnics and barbecues. When people are away from their kitchens, maintaining food safety can become challenging, and the accessibility of soap and water for washing hands and surfaces is often limited, increasing the risk of cross-contamination from raw to cooked foods.

Symptoms of food poisoning can range from mild to severe and typically include nausea, vomiting, abdominal pain, and diarrhea, which may be bloody. Headaches, muscle aches, and fatigue can also accompany these gastrointestinal issues. The onset and intensity of symptoms depend on the specific pathogen involved, with bacterial and viral agents sometimes causing reactions within hours.

Open spaces also mean less access to soap and water for washing utensils, surfaces, and hands, which increases the risk of spreading bacteria, for example from raw meat to other food.

To mitigate these risks, experts advise taking several precautions. Ensuring food is kept at safe temperatures, ideally using a cooler with ice packs, is crucial. Thoroughly cooking all foods, especially meats, and avoiding cross-contamination between raw and cooked items are essential steps. Practicing good hand hygiene, washing hands frequently with soap and water, particularly before eating or handling food, is also vital. Being mindful of food preparation and storage, even during outdoor events, can make a significant difference in preventing a summer of sickness.
