Understanding Salmonella and Its Impact on Health
Salmonella is one of the most common bacterial infections that affect people worldwide, causing food poisoning and gastrointestinal illness. This infection is transmitted through contaminated food, water, or contact with infected animals. At Gleneagles Hospitals, we often see cases of Salmonella among patients who have consumed improperly prepared or stored food. Globally, there are 93 million cases of Salmonella infections reported each year, with over 140,000 cases occurring annually in Malaysia alone. While most people recover without requiring specific treatment, Salmonella can lead to serious health complications, especially for vulnerable populations such as children, the elderly, and those with compromised immune systems. In this article, we will provide a comprehensive overview of Salmonella, including its causes, symptoms, prevention methods, and treatments, along with helpful tips to reduce the risk of infection.
Salmonella in Malaysia and Its Rising Cases
In Malaysia, Salmonella outbreaks have been observed in both urban and rural areas, with food safety and hygiene becoming critical concerns. Recent studies show a rise in foodborne illnesses due to improper food handling and storage. In fact, health authorities report that nearly 60% of foodborne infections are caused by Salmonella, especially during festive seasons when food preparation and consumption increase. These outbreaks often occur in environments with poor sanitation and improper cooking methods, highlighting the need for better food safety practices across the nation. It is crucial to follow proper hygiene practices in food preparation and storage, especially in households and restaurants, to mitigate the risks of infection.
Preventing Salmonella Infections: Practical Tips for Families and Communities
Preventing Salmonella infections is possible by adopting practical, easy-to-follow measures that promote food safety and personal hygiene:
Practice Proper Hand Hygiene:
Wash your hands thoroughly with soap and water before and after handling food, especially raw meat, eggs, or unwashed fruits and vegetables. This is one of the simplest and most effective ways to prevent the spread of Salmonella.
Clean Food and Surfaces Regularly:
Regularly clean your kitchen surfaces, utensils, and cutting boards to prevent cross-contamination between raw and cooked foods. Use separate cutting boards for raw meat and vegetables, and wash them thoroughly with hot, soapy water after use.
Frequently Asked Questions about Salmonella

Salmonella infections typically last from 4 to 7 days, with symptoms such as diarrhoea and stomach cramps gradually improving. However, some individuals may experience symptoms for longer, particularly if complications like dehydration arise. In severe cases, it may require antibiotic treatment.
4. Are children and the elderly more at risk for Salmonella infection?
