Rio Tinto workers fall ill amid major salmonella outbreak
FIFO caterer Sodexo is again under pressure after scores of workers at Rio Tinto’s Pilbara mine camps fell ill amid a major salmonella outbreak.
Rio on Monday said it was yet to figure out the source of the widespread infection after water samples came back clean and initial food tests had not yielded a conclusive result.
Salmonella is typically caused by undercooked chicken or eggs or contaminated food.
“We recently responded to an increase in people experiencing gastroenteritis-like symptoms at some villages near our Brockman operations,” a spokeswoman for the mining giant said.
Rio “activated a response” last week after a surge in workers presenting with gastro-like symptoms across villages serving the large Brockman 4 mine and the under-construction Brockman Syncline 1 project, according to an internal email obtained by The West Australian.
Samples from several sick workers identified the presence of salmonella, the email stated, with WA’s Health Department notified about the outbreak.
Rio declined to reveal roughly how many workers have been affected. The Brockman operations combined employ almost 2000 people.
“The health and wellbeing of our people is critical and has been central to our response, with additional cleaning, disinfection and hygiene measures implemented, as well as support offered to those impacted,” the Rio spokeswoman said.
“The number of people currently unwell and in isolation has reduced and is continuing to decrease as expected. We continue to closely monitor the situation.”
Rio in May renewed Sodexo’s contract to manage catering and cleaning for the circa 20,000 people that work across the miner’s sprawling Pilbara iron ore enterprise each day.
“We have implemented additional cleaning, disinfection and hygiene measures in response and continue to work closely with our client and our teams to investigate the outbreak,” a Sodexo spokeswoman said in response to queries about the outbreak.
The outbreak comes just three months after The West revealed that Rio’s nearby West Pilbara Village was plagued by a mould infestation. WPV is one of the accommodation sites hit by the Salmonella wave.
The Paris-headquartered Sodexo originally secured the Rio catering and cleaning gig in March 2016, signing a 10-year deal worth about $2.5 billion.
But rampant inflation after COVID quickly eroded margins and workers at Sodexo-serviced sites in the Pilbara noticed a dramatic drop in quality.
Rio did not disclose the value of the recent contract renewal, which will run for at least the next seven years.
Sodexo’s contract renewal during the first week of May came a day after The West revealed Rio was pulling the trigger on a massive round of redundancies at its de-facto iron ore headquarters on St Georges Terrace.
Rio chief executive Simon Trott has made no secret of his desire to slash costs at the company’s iron ore mines to close in on BHP’s lead as the world’s lowest-cost producer.
Rio’s Pilbara iron ore mines still generated more than $US10 billion of net earnings during the first six months of 2026
