Severe allergic reactions
to foods are becoming more and more common. Occasionally allergic
reactions can be life-threatening and people who know they
are at risk must always remain vigilant when food is around.
The ingredients most commonly
associated with severe reactions are peanuts; tree nuts (such
as almonds, hazelnuts, cashew, Brazils, walnuts); and seeds
(such as sesame, poppy). Extremely small amounts can trigger
extreme allergic reactions in sensitive people.
Many manufacturers, retailers
and caterers have responded well to the problem by improving
customer information. But customers are still being "caught
out" by unexpected ingredients after receiving false assurances
from staff that a particular food product is safe. Prompt
medical attention saves many lives, but a few are not so lucky.
In Britain, there are about six reported deaths each year
due to food induced anaphylaxis. Most of these fatal reactions
are triggered by food eaten out. The true number of deaths
may in fact be higher and may include cases of food-triggered
asthma.
The Anaphylaxis Campaign
is a registered charity, launched after the death of the founder's
daughter on October 26, 1993. Sarah Reading, who was a 17-year-old
hairdresser, died after eating a slice of lemon meringue pie
containing peanuts. Sarah knew she was allergic and had no
idea peanuts were present in the dessert, which she bought
in a restaurant.
In addition, the campaign has produced the following
notes.
Some key questions
Q
What is anaphylaxis?
A
Anaphylaxis is a severe allergic reaction - the extreme end
of the allergic spectrum. The whole body is affected, usually
within minutes of exposure to the allergen but sometimes after
hours. Causes include food, insect stings and drugs
Q
What are the symptoms?
A
Any or all of the following symptoms may be present:
swelling of throat and mouth
difficulty in swallowing or speaking
difficulty breathing - due to severe asthma or throat
swelling
hives anywhere on the body, especially large hives
generalised flushing of the skin
abdominal cramps, nausea and vomiting
sudden feeling of weakness (drop in blood pressure)
collapse and unconsciousness
Q
What foods trigger life-threatening allergic
reactions?
A
The most common culprits are peanuts and tree nuts (such
as walnuts, Brazils, almonds, hazelnuts).
However, other foods may be implicated. Any customer who
claims to suffer life-threatening allergic reactions to a
food should be taken seriously. Foods which sometimes cause
severe reactions include eggs, dairy products, sesame seeds
and other seeds, shellfish, fish, soya, and pulses.
Q
What kind of quantities can
trigger a severe allergic reaction?
A
For some people, tiny traces of a particular food can cause
anaphylaxis.
Q
How common is anaphylaxis?
A
Statistics are hard to come by, but more than one child in
100 is believed to suffer severe allergic reactions to peanuts,
tree nuts or both. A small but significant number are affected
by other foods.
Q
How do these people protect themselves?
A
Many carry medication, to be taken if they inadvertently
eat the food that affects them. But first and foremost, they
must seek to avoid the offending food. They need accurate
information about ingredients of foods they are about to eat.
Q
What can catering staff do?
A
Listen carefully and sympathetically to any customer who
asks about ingredients. Take the enquiry seriously. Tell the
truth about what's in a dish. If you don't know or aren't
sure, never guess.
Q
What can catering managers do?
A
Managers can devise a system whereby there is always at least
one staff member on duty who has access to accurate ingredient
information. Staff with any queries about any dish on the
menu can go to that person for help.
Customers with allergies can be encouraged to question staff.
Signs can be displayed stating: "Severe food allergies. We
welcome enquiries from customers who wish to know whether
any meals contain particular ingredients."
Managers can minimise risks by seeking to avoid situations
where cross-contamination can occur. The next page contains
practical advice for managers and staff.
What can caterers do?
Guidance for managers and other senior staff
Ensure there is always a nominated person on duty
who knows, or can find out, the ingredients of all dishes.
Encourage serving staff to make all enquiries to
that staff member. Impress on them how important this is.
Ask suppliers to provide accurate written details
about all ingredients, including any planned changes.
Try to avoid the indiscriminate use of nuts, eg
chopped nuts as a garnish, unless this is an essential part of
the recipe.
If a dish is meant to contain nuts, why not make
sure this is reflected in the name: Eg nut and carrot salad. Apply
this consistently.
If possible, keep certain preparation areas designated
as nut free
Put up a prominent sign encouraging people with
allergies to question staff.
Include a prominent statement on the menu encouraging
customers with severe allergies to question staff. For example,
this could state: "Some of our dishes contain nuts. If you are
allergic to nuts, please ask the waiter to suggest a nut-free
meal."
Try to ensure that where a dish contains potent
allergens - particularly nuts - this is indicated in some way
on the menu. Some restaurants adopt a circled N. Apply this rule
consistently.
Organise for your staff a training session on allergies.
Make sure that all new staff members (including part-time and
casual staff) are aware of serious allergies and know how to handle
a customer enquiry.
Guidance for serving staff
If a customer claims to have a life-threatening
food allergy, take the customer seriously. Peanuts and tree nuts
(such as almonds, Brazils, walnuts and hazelnuts) are the foods
most commonly implicated. But other foods may be mentioned. These
may include sesame seeds and other seeds, milk, eggs, soya, shellfish,
fish, pulses (peas, beans, lentils etc) and fruit.
Find out which member of staff has access to accurate
information about ingredients. Approach that person if you need
information.
If there is any serious doubt about whether a
food is free of a certain ingredient, such as nuts, admit to the
customer that you are unsure.
If, on examining his meal, a customer realises
it contains nuts and asks you to replace it, remember it is not
enough simply to pick the nuts from the plate and return it to
the customer. Tiny traces that remain may be enough to cause a
severe allergic reaction.
If there is a gateau covered in nuts on the sweet
trolley, ensure that no nuts could possibly be transferred to
adjacent sweets.
Specific points for all staff
Remember that cooking in unrefined groundnut oil
(peanut oil) may leave traces of nut protein in the food being
cooked.
Any oil that has previously been used to cook
products containing nuts may contain traces of nut proteins.
If you are preparing food for someone with a severe
allergy, beware of transferring food from one dish to another.
Remember that salad dressing may be made from
unrefined nut oil.
Hands, utensils, cutlery and work surfaces should
be washed scrupulously after handling foods containing potent
allergens.
What to do in an emergency
If an allergic customer becomes ill, it is likely
that that person - or someone with them - will state that he/she
is suffering from an allergic reaction. They may use the word anaphylaxis.
This is the action plan to follow:
Immediately send someone to dial 999 and give the
following information:
This is an emergency. A customer has collapsed and
we believe they are suffering from anaphylaxis (pronounced ana-fill-axis).
Give the address and postcode of your establishment
- clear enough so that the ambulance crew will know exactly where
to come.
Someone should be sent to stand at the restaurant
entrance to direct the ambulance crew to the patient.
Ask other customers if there is a doctor in the restaurant.
Staff trained in first aid should make a point of
learning how to recognise allergic symptoms and what to do if someone
suffers anaphylaxis.
