Coimbatore restaurants adapt to ban on mayonnaise made from raw eggs
Following Tamil Nadu government's ban on the use of mayonnaise made from raw eggs, food business operators (FBOs) in Coimbatore have adapted to the regulation. The one-year ban, in effect since April 8, 2025, is intended to prevent food-borne illnesses caused by microbial contamination.
The Food Safety and Standards Authority of India (FSSAI) had cited risks associated with raw egg-based mayonnaise, which can be a breeding ground for pathogens such as Salmonella typhimurium, Salmonella enteritidis, Escherichia coli, and Listeria monocytogenes, especially when not stored at recommended temperatures (0–5°C).
In a promising development, the ban appears to have had limited economic impact on eateries in Coimbatore due to the availability of alternatives and increasing public awareness. Many restaurant owners report that customers are more conscious about food safety and are willing to accept minor taste differences or price increases if safety is ensured.
According to Ramesh Babu, General Manager of restaurant chain Cockraco in the city, the switch had been made well in advance as it moved to eggless mayonnaise over three years ago.
'We procure in bulk from trusted manufacturers. Any hotelier's concern must be to provide good quality and hygienic food. If the mayonnaise costs a bit more, the food item can cost a bit more too - a shawarma that was ₹ 100 can be sold at ₹ 120. Customers are willing to pay for safety', he said.
He also noted a behavioural shift among consumers. 'Earlier, customers would request multiple servings of mayonnaise. That demand has reduced significantly', he said.
Shruthi S., who runs Momolicious in the city, said her team uses boiled egg whites as a viable substitute. 'Customers initially noticed the difference in taste, but have adjusted. The business has not been affected economically. We have simply explored what we can do differently to ensure that quality and safety go hand in hand', she said.
Customers in the city have also welcomed the change. K. Sneha, 22, from Pappanaickenpalayam said she could not find much difference in the taste of mayonnaise after the ban.
T. Anuradha, FSSAI Designated Officer for Coimbatore, said various steps are being taken to raise awareness on the ban in the city.
'Awareness meetings were held with fast food sellers on Wednesday. Queries of the restaurant owners regarding the mayonnaise ban were resolved, with alternatives being suggested. They received training on essential safety measures, food storage practices and pest control, and were also informed that the FSSAI would take strict action against eateries not complying with the same', said Dr. Anuradha, adding that FBOs have been extremely cooperative towards the change.

Maintaining India's progress in food safety standards
This year, the theme of World Food Safety Day, which is observed on June 7, is 'Food Safety: Science in Action'. It is an opportune moment to reflect on India's journey, evolving from a narrow focus on preventing food adulteration to embracing a more comprehensive, science-based approach to food safety. But despite the progress, there are gaps and challenges. India's journey on food safety began with the Prevention of Food Adulteration (PFA) Act of 1954, which viewed food safety as a simple, binary issue — food being adulterated or not. This approach treated all contaminants alike, whether they were intentionally added adulterants, food additives, pesticide residues, veterinary drug residues, or even naturally occurring toxins. The quantity consumed was not considered. The turning point was the enactment of the Food Safety and Standards Act, 2006, which established the Food Safety and Standards Authority of India (FSSAI). Drawing on international best practices, particularly those of the Codex Alimentarius Commission, the FSSAI adopted a risk-based approach to food safety. This included setting maximum residue limits (MRLs) for pesticides, defining safe levels for food additives, and adopting standards for contaminants and veterinary drug residues. By 2020, the FSSAI managed to develop and align India's food safety standards so that they were almost on a par with those in advanced countries. However, this rapid progress also exposed certain weaknesses. The gaps and challenges in risk assessment A fundamental issue is the lack of India-specific toxicological studies. Most safety standards, including MRLs for pesticides and acceptable daily intake (ADI) values for food additives, are based on international data, which may not accurately reflect Indian dietary habits, agricultural practices or environmental conditions. The absence of total diet study (TDS) further complicates risk assessment. Such studies are essential to assess the cumulative exposure of consumers to various contaminants through their entire diet. Without TDS, India relies on fragmented data, which weaken the scientific basis of its safety standards. Another challenge is effective risk communication. Technical terms such as MRLs and ADIs are expressed in minute quantities (parts per million, or ppm, or parts per billion, or ppb) – that are difficult for consumers to understand. These can lead to confusion, especially when safety limits are revised. For instance, the decision to revise the MRL for pesticides from a highly restrictive 0.01 mg/kg to a more practical 0.1 mg/kg led to public concern, with many interpreting it as a reduction in safety. An example of legacy issues A persistent legacy issue is the regulation of monosodium glutamate (MSG), a flavour enhancer that has been extensively studied and consistently found to be safe. Since 1971, the Joint Expert Committee on Food Additives (JECFA) has declared MSG safe for consumption. In 1987, the JECFA allocated an 'ADI not specified' status to MSG. All countries follow this global consensus now. In India, MSG regulations have evolved significantly. Initially, MSG was only allowed in meat products, but its use has gradually been permitted in all foods, but with a mandatory warning label that it is unsafe for infants. This is in sharp contrast to other countries, where MSG is recognised as a safe food additive, and outdated warning labels have been removed. The warning label in India is misleading because glutamates (naturally occurring compounds chemically identical to MSG) are abundant in everyday foods such as tomato, mushroom and garlic, as well as breast milk. As a result, consumers are often left with the mistaken belief that MSG is inherently harmful, leading to unnecessary fear and confusion. As a result, consumers are often left with the mistaken belief that MSG is inherently harmful, leading to unnecessary fear and confusion. Such a legacy approach contradicts global scientific consensus and exposes the challenge of balancing consumer concerns with scientific evidence. It also reflects a broader problem, which is India's tendency to allow some outdated regulations to persist, even when they conflict with current scientific understanding. A path to greater scientific rigor India has made significant strides in food safety, but sustaining this progress requires targeted efforts. Investing in India-specific research, including localised toxicological studies and a comprehensive TDS, is vital to understand cumulative exposure to contaminants. Risk communication should be improved by simplifying scientific messages and replacing confusing labels, such as those for MSG, with clear, evidence-based information. Strengthening the capacity of risk assessors through continuous training ensures that they stay updated with the latest science for sound decision-making. Regular reviews and updating standards in line with new research, while maintaining transparency, are essential. Finally, building public trust through open and consistent engagement with stakeholders including industry, consumers, and the public is key. These steps will help India uphold and advance its commitment to safe, science-based food systems that protect public health and promote informed choices. The FSSAI has laid a strong foundation for food safety in India, but sustaining this progress requires a commitment to science, transparency, and public education. Regulatory decisions must be driven by evidence rather than public fears or out-dated perceptions. As we look ahead, India must continue to balance scientific rigour with effective risk communication, ensuring that consumers are informed, confident, and protected without harbouring unnecessary fear. Pawan Agarwal is the former CEO of the Food Safety and Standards Authority of India. He is currently the CEO of the Food Future Foundation (India), a non-profit organisation, and a Senior Adviser to the International Fund for Agricultural Development (IFAD), a global organisation

Nanoplastics can make E. coli infections worse: study
Nanoplastics are bad news even though each one is only as small as a smoke particle. Research has shown that micro- and nano-plastics are present at the top of the tallest mountains, at the bottom of the deepest trenches, and even in our bloodstream, tissues, and in newborns as well. Their build-up has many toxic effects, including damage to cells and the genetic material inside. Now, a new study from researchers at the University of Illinois, Urbana-Champaign, has revealed that nanoplastics aren't just risky on their own: they also increase the risk from pathogens. The researchers found that nanoplastics with positively charged surfaces could make Escherichia coli, a foodborne pathogen, more virulent. The findings were published in the Journal of Nanobiotechnology. How bacteria work E. coli bacteria have a negative charge on their outer membranes. This can attract positively charged nanoplastics and increase the stress on the bacterium, making it produce more Shiga-like toxins. These are the proteins E. coli secrete and which cause disease. In older studies, scientists have looked at the impact of charged surfaces on non-pathogenic bacteria. The new study examined how charged surfaces affected a particular strain of E. coli. Similarly, while previous studies focused primarily on free-floating cells, the new one studied both free-floating cells and biofilms — a community of bacteria sticking to each other over a surface. Biofilms are hotspots where bacteria exchange genetic material with their neighbours. The research process The team members used a pathogenic E. coli strain that was resistant to the antibiotic rifampicin. They cultured the strain on agar plates and a nutrient-rich liquid medium called LB broth. Then they exposed the bacteria to polystyrene-based nanoplastics with three kinds of charges: positive, negative, and neutral. The team also cultured a second set of E. coli cells in LB broth for use as a control. This group wasn't exposed to nanoparticles. Finally, the researchers observed the growth of the free-floating cells and the biofilm at seven- and 15-day intervals, and used different tests to quantify the growth. For the study's purposes, the researchers used an environmental scanning electron microscope (ESEM) to track interactions between nanoparticles and free-floating cells. Unlike microscopy techniques that require samples to be prepared in protracted processes, ESEM can image 'wet' samples without too much preparation. It also operates in a low-vacuum or controlled gas atmosphere that prevents natural fibres and cellulose from becoming charged. The scientists conducted two tests to measure the concentration of carbohydrates and proteins in the biofilm. They performed a catalase assay to determine the cells' response to oxidative stress. E. coli produce the catalase enzyme to protect themselves against oxidative stress. Higher stress would mean more catalase activity. The team also extracted RNA from the bacteria for study, because gene transfers take place across biofilms. Changes in RNA may indicate such transfers have happened. What the study found The investigations revealed that nanoplastics with surface charges did add to the toxicity of bacterial cells. At first, charged nanoplastics kept cells from growing. But some cells eventually overcame the stress and began to grow. The development and viability of cells exposed to charged nanoplastics were different from those of cells that weren't. Changes in the bacterial RNA suggested genes were changing to ensure the E. coli survived better and became more able to cause disease. The study said both positively and negatively charged nanoplastics caused these changes. Beena D.B., assistant professor of biology at Azim Premji University's School of Arts and Sciences, has conducted preliminary work on the effect of microplastics on soil microbes and said her team had observed similar results. She cautioned that microplastic-induced biofilms are a significant health hazard and that increasing horizontal gene transfer between microbes raised the risk of them developing antibiotic resistance. It also causes excessive production of proteins that contribute to more severe disease, she added. (Manaswini Vijayakumar is interning with The Hindu.)
