In a bold and preventive public health move, the Tamil Nadu government has implemented a statewide ban on the manufacture, storage, sale, and distribution of mayonnaise prepared using raw egg, effective from April 8, 2025, for a duration of one year. This action is intended to reduce the risk of foodborne illnesses that may arise from the consumption of improperly prepared or stored mayonnaise, which often acts as a breeding ground for harmful bacteria.

Why Raw Egg Mayonnaise Was Banned

Mayonnaise, a semi-solid emulsion traditionally made with egg yolk, vegetable oil, vinegar, and seasonings, is a popular condiment in many food items including shawarma, burgers, and sandwiches. However, when raw eggs are used, especially in unregulated settings such as street food joints or smaller food businesses, the risk of microbial contamination increases significantly.

According to the notification by R. Lalvena, Principal Secretary / Commissioner of Food Safety, the improper storage and preparation of raw egg mayonnaise can lead to contamination from dangerous pathogens such as:

• Salmonella typhimurium

• Salmonella enteritidis

• Escherichia coli (E. coli)

• Listeria monocytogenes

These microorganisms can cause serious foodborne diseases, particularly in vulnerable populations such as children, pregnant women, and the elderly.

Legal Backing for the Ban

The notification was issued under Section 30(2)(a) of the Food Safety and Standards Act, 2006 (Central Act 34 of 2006), a provision that allows food safety commissioners to issue temporary restrictions to safeguard public health.

The legal framework empowers authorities to prohibit unsafe food practices when there is a potential risk to consumer health. In this case, the state government deemed it necessary to intervene proactively to curb the increasing incidence of food poisoning attributed to the use of raw eggs in mayonnaise.

Impact on the Food Business Industry

This ban has direct implications for:

• Restaurants and eateries, particularly those serving fast food and continental cuisine.

• Street food vendors, many of whom rely on ready-to-serve condiments.

• Packaged food companies that manufacture egg-based spreads.

Food businesses will now have to either switch to eggless mayonnaise or use pasteurised eggs, which are considered safer alternatives. Those failing to comply with the ban could face legal action, including fines and closure of operations under the relevant sections of the Food Safety Act.

Public Health Concerns Prompting the Action

The decision is rooted in growing concerns over public health and hygiene standards, especially after multiple reports of food poisoning incidents across the state in recent months. While specific data on outbreaks linked to raw egg mayonnaise wasn’t cited in the notification, the pattern of illnesses prompted the Food Safety Department to act pre-emptively.

Food poisoning from Salmonella or E. coli infections can cause:

• Severe diarrhoea

• Vomiting

• Fever

• Abdominal cramps

• In extreme cases, kidney failure or death

The prohibition aims to reduce such incidents and promote better food safety standards across the hospitality and food processing sectors.

Shift Towards Safer Food Practices

This move is expected to usher in a shift towards more hygienic and safe food preparation practices, especially in smaller and unregulated food businesses. It also opens the door for innovation in egg substitutes, including:

• Vegan mayonnaise alternatives

• Pasteurised egg formulations

• Eggless emulsions made with soy, milk proteins, or starches

The regulation could boost the demand for these alternatives, thereby benefiting companies that are aligned with food safety compliance.

How Consumers Are Affected

For the general public, the ban offers a layer of protection against unintended health consequences caused by unsafe food. Consumers who frequently eat shawarma, sandwiches, or salads with mayonnaise dressing should be cautious and check whether the product contains raw eggs.

The Food Safety Department may soon require restaurants to disclose ingredients in mayonnaise-based dishes, and label compliance checks may be intensified over the coming months.

Reactions from the Food Industry and Experts

While the public health community has largely welcomed the move, some food business operators have expressed concerns about the impact on their operations. Transitioning to safer alternatives may increase costs, especially for smaller establishments.

However, experts agree that safety outweighs convenience, and that the ban should be seen as a temporary but necessary measure to clean up unsafe practices in the food industry.

Future of the Ban

The current ban is valid for one year, but the government will likely monitor its effectiveness and consider extending it based on:

• Incidence rates of foodborne illnesses

• Compliance levels among businesses

• Public response and health outcomes

A comprehensive review may lead to permanent regulatory measures or revised food safety standards regarding egg-based products.

Conclusion: A Necessary Step Towards Safer Food in Tamil Nadu

The Tamil Nadu government’s decision to ban raw egg-based mayonnaise is a precautionary and proactive move in the realm of public health. By invoking its powers under the Food Safety and Standards Act, the state has sent a strong message that consumer health and safety take precedence over convenience and cost-cutting.

As food safety becomes an increasingly important public issue, such regulations may pave the way for more stringent food standards across India, ensuring a safer food ecosystem for all citizens.
