Prevention and treatment of food poisoning in summer

Food poisoning is a common concern during the summer months when warmer temperatures can facilitate the rapid growth of bacteria in food. Learn how to prevent and treat food poisoning with these essential guidelines:

Understanding Food Poisoning

Causes of Food Poisoning

Food poisoning occurs due to consuming contaminated food or beverages containing harmful bacteria, viruses, parasites, or toxins. Common causes include improper food handling, inadequate cooking, and cross-contamination.

Symptoms of Food Poisoning

  • Nausea
  • Vomiting
  • Diarrhea
  • Abdominal pain and cramps
  • Fever
  • Weakness and fatigue

Prevention Tips

Food Handling Practices

  • Cleanliness: Wash hands, utensils, and surfaces thoroughly before and after handling food.
  • Separation: Keep raw meats separate from ready-to-eat foods to prevent cross-contamination.
  • Cooking Temperatures: Cook foods to the appropriate internal temperatures to kill harmful bacteria (e.g., poultry to 165°F/74°C).
  • Storage: Refrigerate perishable foods promptly and properly store leftovers to prevent bacterial growth.

Safe Outdoor Cooking

  • Grilling Safety: Use separate utensils and plates for raw and cooked meats. Ensure meats are cooked evenly and thoroughly.
  • Picnic Precautions: Keep cold foods chilled with ice packs and hot foods insulated to maintain safe temperatures.

Water and Beverages

  • Safe Drinking Water: Drink bottled water or boiled and filtered water when unsure of the water quality.
  • Ice Safety: Use ice from safe water sources or commercially packaged ice.

Treatment Strategies


  • Fluid Intake: Drink plenty of clear fluids such as water, broth, or electrolyte drinks to prevent dehydration caused by diarrhea and vomiting.

Dietary Adjustments

  • BRAT Diet: Initially consume bland, easily digestible foods like bananas, rice, applesauce, and toast to soothe the stomach.
  • Avoid Certain Foods: Avoid spicy, fatty, or dairy-rich foods until symptoms subside.


  • Antidiarrheal Medication: Over-the-counter medications like loperamide can help relieve diarrhea symptoms, but consult a doctor if symptoms persist or worsen.

When to Seek Medical Help

Severe Symptoms

  • High Fever: Temperature above 101.5°F (38.6°C).
  • Persistent Vomiting: Inability to keep liquids down.
  • Bloody Stools: Indicates potential bacterial infection or more severe condition.
  • Signs of Dehydration: Decreased urine output, dry mouth, dizziness, or lightheadedness.
