Anyone heard this claim about workers in bakeries?
 

A friend claimed that someone he worked with works in a major bakery
has to wear something that looks like a "space suit" when this person
makes fat free baked items. Any idea about why this would be the
case, or does this sound like total nonsense? Supposedly, there is a
very dangerous ingredient being used, but looking at the labels, I
found nothing that would suggest workers should wear gloves and masks
for "protection" other than what one might consider doing if he/she
worked in any bakery environment.

Thanks in advance.
