One person died while six others were treated for what is suspected to be food poisoning at Swakopmund.
The police, however, said the exact cause of the poisoning is unknown, as the postmortem will only be conducted tomorrow.
According to the police report, the family of seven, between the ages of two and 30, prepared dinner on Saturday of porridge, oshikandela milk, and already-cooked pieces of chicken bought from a local supermarket.
It is alleged that in the early morning hours of Sunday, the wife went to the bathroom because of stomach pain.
She eventually got weak and could not move. The 26-year-old woman regained strength four hours later and noticed that everyone else in the house was unconscious.
Her 30-year-old husband, Alfeus Amadhila, however, died.
NamPol's Erongo Community Affairs Commander, Inspector Ileni Shapumba, said a postmortem to determine the cause of death will be conducted tomorrow.
