Synthetic dyes alleged in fish sold at Bihar market

A video circulating on social media has prompted food safety officials in Katihar district, Bihar, to investigate alleged use of synthetic dyes on fish sold in local markets. The footage, reportedly from the Mirchhaibari fish market area, shows a woman applying red and turmeric-coloured synthetic coating to fish, with vendors allegedly confirming the practice to enhance the appearance of freshness.

The video has sparked concerns about the use of unauthorised additives and potential food contamination. Synthetic dyes applied to food items pose health risks to consumers, particularly when the chemicals used are not food-grade or approved for consumption.

The District Magistrate of Katihar has classified the alleged practice as food adulteration and directed food safety inspectors to conduct thorough investigations into the matter. Officials have warned of strict action against vendors found engaging in such practices in violation of food safety regulations.

The incident highlights ongoing concerns about quality control in food markets across Indian cities and the need for vigilance by both consumers and regulatory authorities. Similar cases of food adulteration have been reported periodically in various parts of the country, prompting authorities to intensify inspections and enforcement of food safety standards.
