Cross contamination versus ate a peanut item

[Avoiding peanuts]

Hello, my daughter is the one allergic to peanuts and I have not eaten a peanut item in 12 years.  I almost don`t even remember what it tastes like.  It is much simpler for me to not have to worry about residue on items in our house (utensils, cups, throwing away the toothbrush that has peanut residue because I ate pb, etc).  She is airborne sensitive, meaning she has gone into rooms and experienced cough and wheezing, then found out later that peanut items have been eaten in there.  For that reason, I just avoid, not worth having to worry about residue in my house, on dishes, etc.

So a few days ago I was at a seminar.  I have no problem with the idea of my eating may contains, and there was a plate of what appeared to be chocolate chip cookies.  I ate one and the first bite tasted like it might be pb.  I was not sure, so I had a second bite.  It tasted exactly like the pb cookies I used to make in college.  It definitely tasted like peanuts.  By this point, I figured I was going to really have to take precautions, so I figured I may as well enjoy the cookie.  I finished the cookie (about eight more bites), and it did not taste like peanuts at all.  So one bite maybe tasted like pb, one bite definitely tasted exactly like pb, and eight bites did not taste like pb.  Can cross contamination do this?  I know that chocolate chip cookies are high risk for cross contamination, but I never thought there would be so much cross contamination that one could actually taste it.  On bite #2, I seriously thought I was eating a pb cookie.

Is this strange or what?  Has this happened to anyone else who eats may contains?

Welcome Avoiding Peanuts!

If they were commercially prepared cookies, there is always the possibility that some of the cookie may have had actual PB dough in it from an earlier run.  That happened to me recently with a container of plain yogurt, some of which tasted like banana.

I'll say that I get that sensation fairly often--of things seeming like peanuts to me. For some reason movie popcorn really smells like peanuts to me quite often. And sometimes food tastes like peanuts. And sometimes it tastes like fish. It's weird.

Asode: movie popcorn smells like peanuts to me too.  It really freaks me out.

Thank you, this is very helpful.  Going Nuts, I think that is exactly what happened.  I just never realized that cross contamination could include an entire bite of peanut.  My daughter does not eat items on shared equipment with peanuts, but if someone allergic to peanuts ate the cookie I ate, I really think it would have been an epipen moment.  Scary.
