Allergens are foods or ingredients which can trigger life-threatening or severe allergic reactions in individuals, according to food law regulations. As part of that regulation, allergens must be declared on prepacked food products and menus.
Display food allergen charts where staff can easily access them when asked by customers about them, to provide comfort and confidence in your safety procedures. This can give customers peace of mind.
What is an Allergen?
An allergen is any substance that causes an allergic reaction in some individuals. Allergies occur when your immune system mistakes an innocuous substance for one that poses danger, sending out antibodies to attack it – leading to symptoms like runny noses, itchy watery eyes or skin itching. IgE antibodies bind specifically with mast cells and basophils where they release chemicals like histamine that dilate and distort blood vessels, making breathing difficult.
Allergens can come in the form of pollen, animal dander or mold spores; allergens may also come in the form of nuts or flowers to touch upon, as well as foods containing proteins naturally found within it as well as synthetic chemical additives added during processing or production.
The FDA has identified eight major food allergens that manufacturers must label foods for as mandated by law. These include milk, eggs, fish, wheat, tree nuts, peanuts, shellfish and soy. Adding sesame to this list recently will ensure accurate labels; FALCPA provisions require that allergen sources must be listed both under their common name as well as category/species names where applicable.
What are the Symptoms of an Allergy?
An allergic reaction occurs when your immune system misinterprets a substance as harmful and overreacts, often with unpleasant symptoms that depend on where the allergen entered your body – skin contact may result in a rash, breathing it in may cause sneezing and coughing, while eating may trigger diarrhea or vomiting. Anaphylaxis requires medical attention immediately as it could prove fatal.
As soon as an allergen enters your system, your immune system immediately begins producing IgE (immunoglobulin E) antibodies to combat it. Once produced, these IgE antibodies attach themselves to mast cells – special cells located throughout your body that release chemicals that irritate skin and dilate blood vessels around it for itching; furthermore IgE antibodies also trigger the release of other chemicals including histamine which your body uses to kill microorganisms but when released excessively can lead to uncomfortable symptoms like hives and itching.
Talk with your doctor or clinical immunology/allergy specialist about your allergy, get diagnosed, and learn which foods you may safely eat. Share this knowledge with those closest to you — such as school nurses, childcare providers and adults who frequently interact with your child — as they can assist in planning ahead for activities while offering emergency treatment if necessary.
How Can I Manage My Allergies?
Allergies can be frustrating, but speaking to your primary care doctor about them may help ease symptoms. Your primary care doctor can listen to and assess your symptoms before providing insight into how allergies work as well as providing connections to specialists like an allergist or ear, nose, and throat doctor as needed.
First step to managing allergy symptoms effectively is identifying allergens that trigger them and eliminating or minimizing exposure to them. You can do this by monitoring pollen counts and limiting outdoor activities when pollen levels are highest, or by taking over-the-counter or prescription medication to control symptoms.
FNS worked closely with the Institute of Child Nutrition on food allergy management by creating and publishing a series of food safety and allergen training fact sheets for food businesses, such as restaurants, cafeterias, school nutrition programs and day care centers. These fact sheets include an overview of nine of the most prevalent food allergies as well as ways to identify allergens on product labels, menu modifications for accommodating those with food allergies as well as the importance of providing educational materials about these allergies.
These resources are designed to be simple, accessible, and action-oriented. This includes posters, fast facts, topic sheets (such as food allergy myths, stress and anxiety management, epinephrine dosing recommendations for diagnosis etc), tips, checklists and much more.
What Can I Do to Help My Allergies?
If you’re experiencing allergies, speaking with a healthcare provider could be invaluable in understanding and treating them more effectively – they may refer you to specialists such as allergists or otolaryngologists (ear, nose and throat doctors).
Make an appointment with your primary care doctor. They will help arrange allergy tests and suggest over-the-counter remedies to manage symptoms such as antihistamines (Benadryl or Diphenhydramine) or steroid nasal sprays and eye drops to control them.
Allergy testing involves applying a small amount of allergen directly onto the skin – typically an arm or back – which may sting or prick, though any discomfort should subside quickly. Your physician may also ask about medications you are currently taking that may interfere with results, as some can alter them significantly.
Three tests can be used to diagnose IgE-mediated allergies: skin prick test, blood tests and physician-supervised oral food challenge. A skin prick test introduces a drop of allergen under your first layers of skin and measures its response; blood tests identify IgE antibodies while physician-supervised oral food challenge introduces suspected food into your system and monitors for symptoms suggesting any allergic response.
Keep a diary to track what triggers your allergy symptoms. Avoiding allergens that cause reactions can help alleviate future ones, while long-term medication such as epipen or auvi-Q may also help control them as prescribed by your physician.
