Mayonnaise is a thick, creamy condiment commonly used in fast foods such as burgers and sandwiches. Traditionally, it is prepared by combining oil, vinegar or lemon juice, and raw egg yolks to achieve its rich texture.
Tamil Nadu has implemented a ban on mayonnaise made with raw eggs due to significant public health concerns, particularly the risk of food poisoning. This decision follows similar bans enacted in Kerala and Telangana, aimed at protecting consumers.
Raw eggs pose high risks as they can harbor harmful bacteria, including:
These bacteria may lead to severe foodborne illnesses if the eggs are not properly cooked or pasteurized.
Infection from these bacteria can result in:
In severe cases, complications may arise, such as blood infections or high fever. Vulnerable groups, including children, the elderly, and individuals with weakened immune systems, are particularly at risk.
Experts caution that raw egg mayonnaise should be consumed within 90 minutes of preparation and stored at temperatures between 0–5°C. Unfortunately, these guidelines are often ignored in many street food establishments. Improper handling and storage can significantly increase the risk of spoilage and bacterial proliferation. Dr. Kalarani R. from Rajiv Gandhi Government Hospital highlights that microbial contamination is frequent when raw eggs are used in unsanitary conditions, especially where food handlers are unaware of hygiene protocols.
Raw egg mayonnaise is commonly found in:
These items are often kept at room temperature, raising their susceptibility to spoilage.
Health authorities and medical professionals argue that mayonnaise made with pasteurized eggs or vegetarian alternatives is significantly safer. The ban aims to prevent large-scale food poisoning cases and encourages better hygiene practices in food preparation. Dr. Venkatesh Munikrishnan from Apollo Hospitals describes this decision as “both appropriate and essential” for safeguarding public health. “Health and hygiene must not be optional when food touches a stranger's plate. The cost of negligence is too high,” he states.
