A friend of a friend gave me some bread for a thank you present. But it tastes like detergent fragrance! Why does this happen? Is it safe to eat? I only use unscented products in my home. And in my opinion the bread is ruined. 
While I agree with the other answer that it's flavoured with something you don't expect, the other possibility is that the bread was wrapped in a freshly laundered, strongly scented cloth. You may be particularly sensitive given that they prefer unscented products. That would affect the crust much more than the inside.
