Following a viral video showing a child consuming food infused with liquid nitrogen, Tamil Nadu’s government issued an advisory banning its use in food. While initially introduced to preserve food quality and shelf life, liquid nitrogen found its way into culinary experiments, leading to health hazards. The Food Safety Department’s circular now restricts its use solely for preserving packaged food, emphasizing the dangers of mishandling or consuming liquid nitrogen and warning of legal consequences for violators. Additionally, liquid nitrogen’s role in cancer treatment, termed cryotherapy, highlights its potential benefits when administered by trained professionals under controlled conditions.
