The man who found a pill in his bottle of milk has admitted it was a tablet that he had been taking which he didn't recognise because it had swollen to four times its size.
Greg Mitchell, of Whitianga, complained to Fonterra last week after finding a tablet in his 2L bottle of light blue milk.
"They sent me an email saying, 'Has anyone been taking pills' and I thought, 'S***, I was'. I had one pill left and I stuck it in some milk and hello, that's what it turned out to be. It had swollen up to four times its size and had changed colour," Mr Mitchell said.
"I've called them up and apologised and have thrown myself on my own stupidity."
Managing director of Fonterra Brands New Zealand, Peter McClure, said in a statement before Mr Mitchell realised his error that they were confident the material had not entered the product during the manufacturing process.
The quality assurance measures at FBNZ are world-class, he said.
"The health and safety of our consumers is our number one priority and we have stringent quality and safety systems in place to ensure this."
