Indian authorities have raided an illegal operation in Mumbai that faked expiry dates and nutritional information on popular food export products manufactured by PepsiCo, Nestle, Coca-Cola and Unilever, seizing goods worth nearly $80,000.

Reuters got exclusive access to the warehouse last week as food officers conducted a six-day investigation. 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.
