This is yet another example of counting pennies while losing dollars.
We argue about trace elements of pig fat, while not even raising a tiny brow about telling lies, dishonesty, suicide bombing, and terrorism overall.
If trace elements of pig fat is responsible for immorality, then large dosage of bacon, lard, and ham should put the people over the edge. Then why it is so that Western societies (in comparison) to Muslim societies have much better track of speaking truth, being honest, and being tolerant?
Why it is that Muslims love to settle in the pig-fat eating societies?
On a serious note:
It is quite possible that trace elements of some poor pig may end up in a food item etc. However a simple test for that is to check if the source of gelatin/fat is animal or the product is using vegetable gelatin.
Food and nutrition science have made tremendous progress in the last 30 years. Current health fads are also driving the manufactured food to be less dependent on animal fats. So guys calm down and enjoy the toffee.
SID_NY did the right thing. He checked with the manufacturer and now he is gulping down (just kidding) the m&ms. That's the way to go.
Listing products willy nilly is just not fair and in fact may border the irrationality.
