Wild boar meat is being ruled out as the cause after a Waikato family was poisoned.
Shibu Kochummen, 35, his wife Subi Babu, 33, and his mother Alekutty Daniel, 62, were found on the floor of their Putaruru home on November 10.
They had just eaten a wild boar curry.
The Waikato District Health Board said today botulism and 1080 tests both came back negative.
Medical Officer of Health Dr Richard Vipond said: "Investigations are ongoing, however there has been no evidence of any public health threat. There is also no evidence that the family's illness was caused by the pork they consumed. It is great news that the family continue to recover."
