Allergy diet - red meat (mammalian) free

This document is part of the ACI Diet Specifications for Adult Inpatients. It is not to be used for patient education.

Aim

To provide a diet that excludes raw and cooked lamb, pork, beef, rabbit, kangaroo, goat, buffalo, venison and their derivatives, to avoid reactions in individuals with a mammalian meat allergy. This is an IgE-mediated food allergy to mammalian meat known as alpha-gal food allergy.

Characteristics

This diet avoids raw and cooked meat, mammalian gelatine and derivatives from mammalian meats including, lamb, pork, beef, rabbit, kangaroo, goat, buffalo and venison. Fish and poultry, including their derivatives (e.g. gelatine) is allowed.

Indications

All patients who report an allergy to red meat should be ordered this diet unless a medical officer or dietitian has advised otherwise.

Nutritional adequacy

This diet can be nutritionally adequate.

Precautions

Some people are so sensitive to alpha-gal, they react to mammalian products and also their milks. If the patient has had suspected milk reactions previously, then also order the Allergy - milk free diet.

It is not possible to provide a full list of all permitted commercial products; the following are general guidelines only. Care should be taken to read all product ingredient lists to determine if the product contains any mammalian meat or derivatives. Clarification is required for foods that contain compound ingredients to determine their components.

Paediatrics

Suitable for use in paediatrics when combined with an age-appropriate diet.
