At least 84 children have died in Nigeria after ingesting a teething formula tainted with a thickening agent normally found in brake fluid, the health ministry says.
The ministry issued a statement saying 111 children have been sickened since the poisonous batch of "My Pikin Baby Teething Mixture" hit shelves in November last year.
Health officials in Nigeria said stores have been returning their stocks of the formula meant to ease children's teething pain, after 34 children died the following month.
But the health ministry did not confirm whether all the tainted products had been recovered.
Many bottles of the formula were determined to contain diethylene glycol, commonly found in antifreeze and brake fluid.
Exposure can cause kidney, liver damage and may be fatal in large amounts.
