Peanut allergy question

I have a mild peanut allergy and just ate a chicken sandwich at Chick-fil-A. I didn’t realize until after I ate it that all of their food is fried in 100% purified peanut oil. I read online that most peanut allergy sufferers do not react to purified peanut oil because of the hotness/purification or something like that. I do not think that I will get sick but I am most worried about my boyfriend. He is severely allergic to peanuts and when I go home tonight I don’t want to give him “the kiss of death”. My question is, how long will the peanut oil stay in my system, what do I need to do and how long do I need to wait before I kiss him, etc. again? Thanks!

Hi, welcome to the forum, you need not worry. As you have consumed peanut oil and your boyfriend will not come in contact with the peanut oil, even if you kiss. If he is allergic to peanuts with the skin contact then precautions may be needed. You can go for thorough mouth wash and that's it. You need not any other precautions. Peanut oil will stay for few hours only. Kissing, should not be a matter of concern. Take care and regards.
