Of all the dietary allergens, allergy to peanuts is undoubtedly the most well-known, and patients frequently worry that exposure to airborne peanut particles will result in a reaction. It has not been demonstrated by research that peanuts aerosolize similarly to fish and shellfish. There shouldn't be any symptoms if a person with a peanut allergy is in the same room as an open jar of peanut butter. However, given the possibility for significant peanut responses, it is undoubtedly advised to use caution when near peanuts, particularly when they are on surfaces or present in other foods. It's possible that residues of peanuts on the counter or a plate are the cause of what appears to be an allergic reaction to peanuts in the air. Luckily, reactions to food allergens in the air are rare and, when they do happen, are usually mild. Most of the time, people with allergies have stuffy noses, runny noses, hives, coughs, and wheezing. 
Food allergies that get into the air are more likely to cause breathing problems in people with asthma. Anaphylactic reactions to allergens in the air are very rare, but they do happen. For example, an 11-year-old boy died last year when his asthma was triggered by his grandmother cooking cod. Most of the time, people react to food allergens in the air when the food they are allergic to is being cooked and proteins rise up into the air. People with allergies to fish or shellfish may have symptoms when fish or shellfish are steamed, boiled, or fried. This is because fish and shellfish release proteins when they are heated. The chance of a reaction goes up as the allergy gets worse. Also, the risk would be higher if you were close to the cooking food and in a small room than if you were farther away and in a large, well-ventilated room. Not only does cooking seafood release proteins that can cause an allergic reaction, but so can cooking eggs and milk. Even someone who is allergic to wheat might get sick if they stand over boiling pasta or stir it. Small pieces of food in the air can also make breathing problems worse. Soy flour, wheat flour, egg powder, and milk powder are all fine to float in the air and breathe in. People who work in bakeries and are allergic to one or more of the flours they use may develop what is called "baker's asthma" after being exposed to flours for a long time and in large amounts. It's crucial to keep in mind that severe allergic responses are uncommon. People who have asthma and are severely allergic to a meal that can aerosolize do have a higher chance of having a reaction. 
When you are worried about a possible reaction, avoid the kitchen because it is better to be cautious than sorry. Allow someone else to handle the work so you can relax. Additionally, always have a working epinephrine auto-injector on hand. The possibility of experiencing a reaction from accidental exposure to peanuts while on an airplane has long been a source of worry for people with peanut allergies. Concerns have been raised specifically regarding reactions that have been claimed to be caused by inhaling peanut dust, peanut butter vapors, or scent, being close to peanuts, or by coming into contact with contaminated surfaces. This is comprehensible. Relax by taking a big breath. Even if you have a peanut allergy, touching, smelling, or inhaling peanut particles won't result in an allergic reaction—at least not the severe, perhaps fatal kind that anyone with a peanut allergy worries about. Unless you consume them, you are not in danger. If you have a peanut allergy, you actually have a reaction to the proteins in peanuts. Your immune system's antibodies are floating around, ready to spring into action if they come into touch with certain proteins. When you consume a peanut, even a tiny quantity, this happens. The peanut-allergic flier can, however, take comfort in the fact that, since the issue was first researched in 2004, data has consistently demonstrated that peanut dust does not become airborne and that inhaling peanut butter vapors does not cause a reaction, that skin contact with either form of peanut is unlikely to cause any reaction beyond local irritation that can be washed off, and finally, that surfaces (including hands) that become contaminated with peanut can be easily washed off. Let's sum up this evidence quickly. 
Even if smelling peanuts won't result in a severe reaction, if you're allergic to them, the fragrance may cause your body to respond since it perceives a threat. "Peanuts have a strong aroma. According to Dr. Kim, some of the tension, worries, and fear that is legitimately associated with anticipating a reaction may be released simply by the smell. It's an instinct for survival. Your body is aware of nearby foods it shouldn't be consuming. According to Dr. Kim, if you have a peanut allergy, you can feel queasy or just a bit weird if you smell them. Furthermore, he adds, "if the person in the seat in front of you happened to consume peanuts and was not very clean, you could perhaps contact it in a chair and have a little bit of a rash or irritation" on the skin. So, if you smell peanuts or are concerned about residue, wipe out the surface, whether it's on an aircraft or at the lunchroom table. Additionally, encourage your child early on not to share food with peers if he or she has a peanut allergy. A separate table for kids with peanut allergies can be necessary if they are too young to understand not to share their food, according to Dr. Kim. There's no reason they can't sit with their pals when they become older, and you feel like they have understood this and can control their instincts. The reported airborne exposures documented in the four studies of self-reported aircraft reactions, including those discussed in our 2012 response to this topic, are difficult to comprehend in the context. 
The drawback of these data is that it is impossible to say what exposure may have taken place or how because the mechanism of these reactions was not verified by a healthcare professional. This is not to be confused with the possibility of a reaction being disputed. The key difference in this discussion's setting is how the issue is being addressed. These therefore still fall under the category of anecdotal evidence, though they are alarming, and they served as the impetus for the aforementioned surface and air exposure studies. The final line is that traveling while having a peanut allergy and coming into contact with probable peanut sources in the cabin is not likely to put the peanut allergic traveler at an increased risk. There is no proof that peanut dust circulates and triggers reactions or that peanut air acts as a catalyst. There is evidence that common airplane surfaces may still be contaminated with peanuts, but there is also evidence that this can be easily cleaned with commercial cleaners that passengers can bring on board themselves. It has also been noted that performing this cleaning lowers the likelihood that a passenger will report an in-flight reaction.
