Hughton saw the Canaries inch to 34 with a hard-fought 1-1 draw at Sunderland despite playing for over an hour at the Stadium of Light with just 10 men after goalkeeper Mark Bunn was sent off for handling outside his box.
But asked if they were now just about safe, he replied: "No. We have continually said the 40-point mark.
"I know there are others who have said they feel it will be less than that, but if you start talking less than that, there are too many teams around us and too many teams below us who are capable of winning games.
"You have only got to look at Southampton winning yesterday and Villa winning yesterday - all of these teams are capable of winning games.
"If we continue to look around that 40-mark, I think that's a fair assessment."
