Here are a few precautions you could take:

1. Avoid contact with all nuts including peanuts, almonds, Brazil nuts, cashew nuts, hazelnuts, pistachios, walnuts and pecan nuts.
2. Read labels carefully. Peanuts, especially, are in a lot of products.
   
3. Check baked products and candy carefully. Many contain nuts of all varieties.
   
4. Take care when eating soybeans, peas and garbanzo beans. They are from the same family as peanuts, and you may have a sensitivity to them as well.
   
5. If you suspectthat you have had an allergic reaction to nuts, you should avoid them completely & get tested.
   
6. Be careful when eating Indian, Chinese and Thai cuisine. Many dishes feature peanuts or are cooked in peanut oil.
   
7. Avoid artificial or imitation nuts. They are usually made with peanuts.
   
8. Do not attempt to reintroduce nuts into your diet if you have experienced a reaction. You must avoid them completely. Carry an EpiPen with you when traveling or eating out.
   
9. Stay away from others who are eating or cooking with nuts.
   
10. Avoid marzipan, chili and egg rolls unless you know for a fact that they do not contain peanuts. Peanut butter is sometimes used to thicken chili and to seal egg rolls.
