Nearly three months after the Nyiragongo volcano erupted in eastern DR Congo, authorities warned local people on Thursday that a salt-like substance in lava flows is unfit for human consumption.
The “whitish mineral substance” is used by the inhabitants of the small local kingdom of Bukumu “for domestic needs in place of cooking salt,” the office of the governor of North Kivu said in a statement.
Scientific analysis revealed “siliceous substances insoluble in water, traces of heavy metals and traces of radioactive substances,” the statement said.
“So it’s not common kitchen salt (and) we strictly ban the consumption of this substance, which is poisonous,” he said.
Mount Nyiragongo erupted on May 23, killing 32 people and destroying several hundred homes in nearby Goma.
