Tiruvallur district, which had been ranked fourth in the country in ensuring food safety recently, launched two mega schemes on Sunday.
Health Minister Ma. Subramanian launched the projects, including procuring one lakh litres of biodiesel under Repurpose Used Cooking Oil (RUCO) and distributing excess food to one lakh people within the district in a day.
Mr. Subramanian flagged off a 4-km walkathon to raise awareness about food safety that began from Avadi Corporation and ended at HVF grounds.
