A Foxconn iPhone factory in Chennai at the centre of a mass food-poisoning incident will extend a week-long closure by an extra three days, a senior official told Reuters.

The factory, which employs some 17,000 people, had been due to resume some operations on Monday but is now expected to restart production with 1,000 workers on Thursday, the official said, adding that the state government had conducted inspections of workers’ hostels.

Last week, protests erupted after more than 250 women who work at the plant and live in one of the hostels had to be treated for food poisoning. Some of the protesters were rounded up by the police but later released.

The incident has thrown a spotlight on living conditions for the workers, most of them women, who reside in hostels near the factory in Chennai.

The Taiwanese contract manufacturer for Apple Inc and other big tech names as well as 11 of its contractors, including those who provide food and living facilities were summoned for a meeting, said the official.

The official was not authorised to speak on the matter and declined to be identified.

The state government asked Foxconn to review services provided to the workers, including power backup at the hostels, food and water, and the directorate of industrial safety and health also recommended providing recreational facilities such as a TV, a library and indoor games, the official added.

According to a separate government source, Foxconn has told state bureaucrats it had “ramped up production too quickly” and would gradually ensure that workers’ facilities were upgraded before they go back to full capacity.

Representatives for Foxconn and Apple were not immediately available for comment.

The gates of the factory, which is on the outskirts of Chennai, were open on Monday and some vehicles were moving in and out but the area was mostly deserted.

The impact on Apple from the closure of the plant, which makes iPhone 12 models and has started trial production of the iPhone 13, is expected to be minimal, analysts have said. But the factory is strategic in the long term as Apple tries to cut its reliance on China’s supply chain amid trade tensions between Washington and Beijing.

The disruption comes as Apple is dealing with pandemic-related supply chain bottlenecks that have hit production. In October, the company warned that the impact of these supply chain problems would worsen during the holiday quarter.

The unrest at Foxconn is the second such involving an Apple supplier factory in India in a year.

In December 2020, thousands of contract workers at a factory owned by Wistron Corp destroyed equipment and vehicles over the alleged non-payment of wages, causing damages estimated at $60 million.

Cupertino, California-headquartered Apple has bet big on India since it began iPhone assembly in the country in 2017. Foxconn, Wistron and another supplier, Pegatron , have together committed roughly $900 million over five years to make iPhones in India.
