I am simply saying the regulation as its presented in the article seems confusing as heck. The manufacturers are indicating they don't care about this market so they are just listing it on the label because the facility is processing sesame. That does not like the right way but I got the impression they don't use the "may" language because its likely there is some trace of it in the product. If they just end up adding some to the ingredients it complies with letter of the law but not the spirit. IMO its confusing as the business what the right path forward is, my interpretation is that they don't care about people with sesame allergies and it probably makes economic sense for large scale facilities, they need to be given better guidance from the FDA other than "prevent cross contamination".
FARE lists sesame allergies as 0.7 million in the US, 2020 might be outdate information though.
