Mars products no longer vegetarian

Also, Bovril had changed away from beef extract to some kind of flavored yeast during the mad cow scare and have recently changed back to Beef . The mad cow scare must be over huh ?
 
I thought gelatin was made from bones. The OP suggests that Mars are now using beef gelatin in their product. Wasn't the use of beef bones stopped when mad cow (CJD) was found in animals. Beef on the bone was banned too. Has the ban been lifted?

The Mars issue wasn't about gelatin it was about Rennet but thankfully now the issue has been resolved.
