Packaging defect, not milk quality, caused odour in Aavin Delite packets

The Madurai District Cooperative Milk Producers’ Union Ltd. (Aavin) has clarified that a foul odour reported in its 500 ml Delite milk packets distributed late last month stemmed from a packaging material defect rather than the milk itself.

The clarification came in the wake of consumer complaints received on July 28, 2026, regarding Delite milk packets that had been dispatched the previous day.

Prompted by the consumer grievances, Aavin launched a detailed technical investigation into the issue.

The inquiry confirmed that the milk contents were safe and uncompromised, and that the unpleasant smell was instead caused by an improper curing process of the poly film material used to seal the packets.

Swift corrective measures were taken upon identifying the root cause. The specific poly film roll responsible for the odour was immediately removed from the milk-filling production line to prevent further distribution, the statement noted.
