Breeds currently on the list are the Pit Bull Terrier, the Japanese Tosa, Dogo Argentino and the Fila Braziliero.
A spokesman for the Metropolitan Police told MailOnline: "The dog was contained by officers and seized. It remains in secure kennels. The dog is a Staffordshire bull terrier, a breed not prohibited under the Dangerous Dogs Act.
"The man's death is not being treated as suspicious - a post-mortem examination at Haringey mortuary on Friday, 24 March gave cause of death as hypovolemic shock and damage to the airway consistent with a dog bite.
"Enquiries by police at Haringey continue to assist the coroner."
A BBC spokesman added: "We are aware of an incident but we cannot comment any further as it's an ongoing investigation."
