A Rotorua man cut the inside of his cheek after biting into a sausage containing a sharp piece of wood described on social media as being like a ''mouldy toothpick''.
Mangakakahi woman Shaq Harpur said her partner, Dion Carlton, discovered the small piece of wood inside a spicy chorizo sausage from a packet they bought at a Rotorua Countdown.
Countdown says it is taking the matter seriously and investigating.
Harpur, a 24-year-old daycare centre teacher, said they bought the sausages from Countdown Fairy Springs in mid-September but only got round to cooking them for dinner last week.
