For almost three decades, a can of citrus soda has been a safer beverage for millions of people in India and the rest of the Global South. Long before the United States and Canada agreed to prohibit brominated vegetable oil (BVO) this year, nations such as India had previously taken this vital step for public health, demonstrating a proactive approach that is sometimes overlooked. 

The US Food and Drug Administration (FDA) only revoked its authorisation for BVO—a synthetic emulsifier associated with thyroid disturbance and organ damagein July 2024, with enforcement scheduled for August 2025. This ended a 55-year era of regulatory uncertainty that began in 1970. In sharp contrast, India implemented a complete ban in 1990, with the United Kingdom leading the way as early as 1970. 

This timeline is more than simply a historical footnote; it teaches a valuable lesson in regulatory philosophy. While the US system developed slowly, plagued by business lobbying and a desire for overwhelming proof, many countries in the Global South took a cautious approach. They prioritised consumer safety based on developing international knowledge, frequently without the need for costly and time-consuming local research. 

The U.S.'s delay reflects a cautious, industry-influenced regulatory system requiring definitive evidence, unlike the precautionary bans in the Global South, says the regulatory history research. This strategy has safeguarded billions of people from possible damage for generations. 

The Precautionary Principle in Action

India's trajectory exemplifies successful, forward-thinking government. By 1990, motivated by early animal studies from Canada and the UK's prohibition, Indian authorities under the Prevention of Food Adulteration (PFA) Act had restricted BVO. This effort was later reinforced by the Food Safety and Standards Authority of India (FSSAI), which created strict import monitoring and standardised safer substitutes such as ester gum. 

The motivators were clear: adhering to World Health Organisation (WHO) and Codex Alimentarius standards to maintain trade compatibility and, most crucially, protecting public health in a country with a large population and an increasing burden of noncommunicable illnesses, such as thyroid problems. 

Why is this important for health in South Asia today? 

The relevance of this early action goes well beyond a single additive. It reveals a significant difference in how health risks are controlled. Preventing long-term, chronic illness through food safety is not only wise but also important for families in South Asia, where the ageing population is increasing and healthcare facilities are frequently overburdened. 

BVO's key concern is its link to thyroid disturbance. Thyroid diseases are already a major public health concern in the area, with India sometimes dubbed the "thyroid capital of the world". Preventing a known possible exacerbating factor from entering the food system for 35 years has clearly had a positive, albeit unquantifiable, influence on public health. 

The current US embargo has prompted increased vigilance throughout the Global South. Nigeria's National Agency for Food and Drug Administration and Control (NAFDAC) issued a public advisory in December 2024, alerting people and importers of the possibility of non-compliant U.S. products entering the market. The alert  urges "vigilance against smuggled U.S. products containing BVO," demonstrating the ongoing commitment to enforcement. 

A Model for the Future 

The tale of BVO demonstrates that good public health policy does not necessarily necessitate the most extensive resources—it only requires political will and a commitment to prudence. The Global South's experience provides a roadmap for handling growing health hazards, particularly when new food technology and chemicals emerge. 

As the globe grapples with complicated food systems, India's 35-year head start demonstrates that putting people first is not just a moral obligation but also a viable and practical public health policy.
