Authorities in India have raided an illicit operation in Mumbai that falsified expiry dates and nutritional labels on authentic food products manufactured by PepsiCo, Nestle, Coca-Cola and Unilever so they ⁠could be exported to other countries.

That's according to a report by Reuters, which said it got access to ⁠the warehouse last week as food officers conducted a six-day investigation and seized goods worth nearly $80,000.

A photographer saw chemicals used to remove manufacturers' original expiry dates and ingredient labels, machines to print and apply replacements and scores of label packs for ​products including Lay's potato chips and Maggi noodles.

India's Maharashtra state, where Mumbai is the capital, has intensified ​a ⁠food safety drive under the new head of the state's Food and Drug Administration, Tukaram Mundhe, whose surprise inspections at elite clubs and restaurants have made him an online and TV celebrity.

'Shocked by scale'
