Coca-Cola may have taken the cocaine out of its fizzy brew over a century ago, but 370 kilograms of the drug have been found in the drink maker's plant in southern France, a local newspaper reports.
The haul has a street value of almost 50 million euros ($A74.2 million), Var Martin reported, citing the city of Marseille's prosecution service.
The cocaine was discovered on Friday in a container delivered from an orange juice supplier in Costa Rica to a Coca-Cola location in Signes, north of Toulon, according to the report.
The head of the plant, Jean-Denis Malgras, described the discovery as a "very nasty surprise" in comments to the paper.
Initial investigations have shown that no Coca-Cola employee was knowingly involved in the drug delivery.
The multinational beverage company is best known for the popular carbonated drink that shares its name.
Coca-Cola was originally intended as a patent medicine and contained small amounts of cocaine as a stimulant until the early 20th century.
