I probably new Kellogg's owned Keebler, but forgot.
Anyway, I found these Waffle Bowls in a store and the labelling looked safe, but I sent an e-mail to Keebler.
i received a lengthy response that they label for the top eight, including a may contain warning for peanuts/nuts. Sesame is not one of the top eight in the US but is in other countries (including Canada) and they label for it as well, including may contain. (I'm not sure if they label for it in the US. Our labels are different because they are french and english, so if you are in the US and dealing with sesame check that information for your country.)
I have trusted Kellogg's labeling for years, so I'm glad to add this to my safe list.
