Morrissey has written an open letter of apology to fans for being forced to cancel yet another string of dates on his South American tour, but has confirmed his Argentina and Brazil shows will go ahead as planned.

The former Smiths frontman had to postpone a month of concerts after being diagnosed with a severe case of food poisoning which left him 'bedridden' for five days.

Posted on fan site, True To You, Morrissey wrote: "The humiliation and mortification I feel on a personal level is too mammoth to be measured," whilst claiming that the contracted the "deadly and delirious bedridden disease" from "a simple restaurant meal of penne pasta and tomato".

Speaking of the illness, Rodrigo Perez, Morrissey's Chilean concert promoter, told Radio Cooperativa: “Within hours, all of them fell sick with severe gastric problems … The hotel has become like an outpatient clinic. There are people who have not been able to get out of bed for 48 hours.”

Morrissey, who has already been forced to cancel a number of 2013 tour dates earlier this year due to a bleeding ulcer in January, added: "I repeat my very servile apologies to any and all who back-packed their way to Peru. Alas, the dark shadow made the same journey.”
