Riff has since closed as the authorities investigate the woman's death.
Chef Bernd Knöller told said in a statement: “Regardless of the reason that may have caused this situation, I want to convey my deep regret for what happened, hoping that soon all these facts can be clarified.”

Mr Knöller said he is fully co-operating with the authorities.
Regional health chief Ana Barceló said: "“We’ve conducted a primary inspection of the establishment and everything appears to be normal.”
“Analytical tests will now be carried out on the food products.”
