Anaphylaxis is a severe, rapid allergic reaction. Warning signs include swelling of the face, lips, or throat, difficulty breathing, a widespread rash, and feeling faint. If suspected, call emergency services immediately, help the person use their adrenaline auto-injector if available, and keep them still while waiting for medical help.
This article provides general emergency-awareness and food-business guidance. It is not medical advice, legal advice or a substitute for accredited practical first-aid training. Organisations must follow applicable national law, emergency-service guidance, workplace procedures and the instructions supplied with the person’s prescribed medication.
Key takeaway: Anaphylaxis is a rapidly developing allergic emergency affecting the airway, breathing or circulation.
Anaphylaxis is a serious systemic allergic reaction that can become life-threatening within a short time. It is recognised primarily through sudden airway, breathing or circulation problems, with or without skin changes such as hives, flushing or swelling. Adrenaline is the recommended first-line emergency treatment. (EAACI)
Food is one possible trigger. Other triggers include medicines and insect stings. In a restaurant, café, takeaway, school kitchen or catering operation, the immediate priority is not to prove exactly which ingredient caused the reaction. Staff must recognise the emergency, call for professional help and apply their emergency procedure without delay.
The reaction may begin within minutes of exposure, although timing varies with the trigger and circumstances. A person can deteriorate quickly even when the first symptoms appear mild. Staff should therefore respond to the pattern and progression of symptoms rather than waiting for every expected sign to appear. (EAACI)
Anaphylaxis is different from a less severe allergic reaction. Isolated itching, a limited rash or localised swelling may not by themselves establish anaphylaxis. However, staff should treat sudden breathing difficulty, throat or tongue swelling, collapse, confusion or signs of shock as an emergency.
For more detail on the underlying distinction, see food allergy versus food intolerance.
The Food Allergen Awareness Training course helps food-business teams understand allergen hazards, customer communication, cross-contact prevention and responsible workplace procedures. It supports awareness and professional development but does not replace practical first-aid certification, medical instruction, national legal advice or organisation-specific emergency planning.
Key takeaway: Use the airway, breathing and circulation pattern to identify the most dangerous anaphylaxis signs and symptoms.
A practical way to recognise anaphylaxis is to look for sudden problems involving Airway, Breathing or Circulation — ABC. Skin or mucosal changes often occur, but they may be absent, so a lack of rash does not make the situation safe. Resuscitation guidance reports that skin or mucosal signs may be missing in some reactions. (Resuscitation Council UK)

|
Other possible symptoms |
Sudden abdominal pain, vomiting or a strong feeling that something is seriously wrong, particularly when combined with ABC problems |
A person does not need to show every sign. Severe airway swelling can occur without hives, while another person may first become faint or confused. Staff should also listen to the customer: statements such as “my throat feels tight”, “I cannot breathe properly” or “I think I am having anaphylaxis” require immediate attention.
Call emergency services immediately when there is:
swelling affecting the tongue, throat or ability to swallow;
noisy, difficult or rapidly worsening breathing;
wheezing accompanied by other allergic symptoms;
sudden collapse, faintness or confusion;
loss of consciousness; or
a known allergy followed by rapidly progressing symptoms.
Do not send the person away, ask them to wait outside or tell them to arrange their own transport. Anaphylaxis requires an emergency medical response.
Key takeaway: Call 112, support prompt adrenaline use and prevent the person from standing or walking.
When anaphylaxis is suspected, call 112, the emergency number available throughout the European Union. Where several staff are present, one person should call while another retrieves the emergency procedure and helps with the person’s prescribed adrenaline auto-injector. Neither action should be unnecessarily delayed. (Digital Strategy)
Recognise the emergency.
Look for sudden airway, breathing or circulation problems. Do not wait for a rash or complete certainty.
Call emergency services.
Dial 112 and clearly state that the person may be experiencing anaphylaxis. Give the premises address, access instructions and the person’s current symptoms.
Use the prescribed adrenaline auto-injector promptly.
Encourage the person to self-administer it. Trained staff may assist or administer it where permitted by national law, their training and workplace procedures. Intramuscular adrenaline is the first-line treatment for anaphylaxis. (EAACI)
Position the person safely.
Keep them lying down. If breathing is very difficult, they may sit up with their legs extended. Do not allow them to stand, walk suddenly or move around unnecessarily. Pregnant people should generally be positioned on their left side while awaiting professional help. (Resuscitation Council UK)
Consider the second prescribed device after five minutes.
If serious symptoms persist after five minutes and a second auto-injector is available, current first-aid guidance supports giving the second dose, ideally in the opposite thigh. Follow emergency-service instructions and the device-specific directions. (Resuscitation Council UK)
Monitor continuously.
Keep checking responsiveness and normal breathing. If the person becomes unresponsive and is not breathing normally, begin cardiopulmonary resuscitation and use an automated external defibrillator if available and staff are trained.
Give a clear handover.
Tell emergency responders what the person ate, when symptoms began, which device was used, the time of each dose and whether their condition changed.
Do not rely on antihistamines to treat airway, breathing or circulation problems. They do not replace adrenaline in anaphylaxis. Steroids are also no longer recommended as routine first-line emergency treatment for anaphylaxis. (Resuscitation Council UK)
Staff should also avoid:
making the person walk to another room;
delaying the emergency call while searching for a manager;
giving food or drink to someone with breathing difficulty or reduced consciousness;
guessing whether the reaction is “serious enough”;
using someone else’s medicine without considering local legal and procedural requirements; or
leaving the person alone.

Key takeaway: Auto-injectors deliver adrenaline into the outer thigh, but staff must follow the exact instructions for the available device.
Adrenaline auto-injectors are designed to deliver a measured intramuscular dose into the outer thigh. Different brands have different safety mechanisms, activation methods and holding times. Staff training must therefore cover the devices that customers, pupils, residents or employees are likely to carry.
For an EpiPen, the general sequence is:
Remove the device from its carrier.
Hold it with the orange end pointing down.
Remove the blue safety release.
Place the orange end against the middle of the outer thigh at a right angle.
Push firmly until the mechanism activates.
Hold it against the thigh for three seconds.
Remove it and keep it available for the emergency responders.
The device may be used through clothing where necessary. The person still needs emergency medical assessment after using it, even when their symptoms begin to improve. (Epipen)
These instructions apply specifically to EpiPen devices. Jext, Emerade and other auto-injectors may operate differently. Staff should never assume that every device uses the same cap, activation pressure or holding time.
A food business should decide in advance:
who calls emergency services;
who meets the ambulance;
which trained roles may assist with an auto-injector;
where the first-aid kit and incident form are kept;
how the area will be cleared while preserving the person’s privacy;
how the suspected dish, packaging and ingredient information will be preserved; and
who informs senior management and begins the incident review.
Practising these responsibilities is more useful than relying on a policy that nobody has rehearsed.
Country variations: EU food-information rules provide a common baseline, but laws governing first aid, workplace responsibilities, access to emergency medication and staff administration of auto-injectors can differ between Member States. National health, education and food-safety rules may add requirements.
Key takeaway: The best emergency response is supported by strong allergen information, communication and cross-contact controls.
Regulation (EU) No 1169/2011 requires information about specified allergens to be provided for food, including non-prepacked food under the relevant national arrangements. The European Commission confirms that allergen information requirements apply to prepacked food and food supplied without prepackaging, including restaurant and café service. The regulation prevents incidents through accurate information; it does not replace emergency-response training. (Food Safety)
Food businesses should use the following controls:
Maintain an accurate allergen matrix based on current recipes and supplier specifications. Do not depend on memory, assumptions or an outdated menu note.
Front-of-house staff should notify the kitchen, verify the exact allergen and explain any cross-contact limitation honestly. See the practical procedure for handling customer allergen requests.
Use appropriate separation, cleaning, storage, equipment and production scheduling. Emergency readiness cannot compensate for weak prevention.
Front-of-house, kitchen, delivery and supervisory staff need different practical knowledge, but everyone should know how to raise the alarm and where to find the emergency procedure.
Test a scenario in which a customer develops breathing difficulty during a busy service. The drill should expose delays, unclear responsibilities, missing contact details and poor access for emergency responders.
Record what was ordered, what was communicated, what was served and how staff responded. Correct the recipe record, supplier data, communication process or training gap that contributed to the event.
Key takeaway: Training should connect allergen prevention with clear, practised emergency responsibilities.
Staff cannot safely manage a severe allergic reaction through goodwill alone. They need accurate allergen knowledge, clear reporting routes and a rehearsed procedure that removes hesitation when every minute matters.
