Germany's Interior Ministry has said it regrets serving pork sausage at a conference on Islam in Berlin earlier this week.
The ministry said the food selection had been designed for the "diverse religious attendance" at the German Islam Conference in Berlin.
But it apologised "if individuals felt offended in their religious feelings".
The event was led by Interior Minister Horst Seehofer, who in March said Islam "does not belong in Germany".
Most of the attendees at the Islam conference were Muslims, local media reported. Under Islamic law, Muslims are forbidden to eat pork.
