Morrissey has courted criticism after he reportedly compared the actions of fast food companies to the recent attacks in Norway.
At least 76 people died last week in two separate attacks which were both orchestrated by far-right extremist Anders Behring Breivik.
Morrissey, a staunch vegetarian, made reference the massacre during a performance in at Stodola Club in Warsaw, Poland earlier this week, according to the Daily Mirror.
Before playing The Smiths' song 'Meat is Murder', he is quoted as saying: “We all live in a murderous world, as the events in Norway have shown, with 97 dead.
“Though that is nothing compared to what happens in McDonald’s and Kentucky Fried Sh*t every day.”
Video footage of Morrissey performing the song has been published on YouTube, but it omits his alleged introduction.
Morrissey's comment is the latest in a string of outbursts in recent months, many of which have focussed on animal welfare.
