Does Taco Bell use horse meat?

NO. taco bell does not use worms in their meat as cheap filler, this implies earthworms and mealworms to be more cheaper than burgers when infact they are not, usually they go for 30$ a pound but with the exception if you were to buy in bulk at a place with a very low price then, if your lucky the worms are 20$ a pound. This worm filler urbanlegend is just a myth, it is not true. If tacobell were to use mealworms as filler those tacos would be very expensive.

There are also other myths such as delivery trucks with boxes labeling the Taco Bell meat as Grade D but edible, also false.
