A factory in Belgium billed as the world’s biggest chocolate-making plant says it restarted operations Monday after closing for six weeks to clean up a salmonella contamination. The AFP news agency reports that the plant – which supplies industry giants such as Hershey, Nestle and Unilever but not to consumers directly – was shut down at the end of June after salmonella bacteria was found in one lot, halting shipments and informing clients in time to prevent contaminated chocolate making its way to shops. A company spokesperson said that while the factory was currently turning out only a “fairly low volume”, it planned to reactivate more production lines “in the weeks to come”.
