Draft Tanzania Standard Ready to eat food for special people with Malnutrition - Specification TANZANIA BUREAU OF STANDARDS 1
Ready to eat food for people with Malnutrition Specification (Draft for comments only) 0. Foreword 0.1 Ready to eat food for people with malnutrition is a Ready-to-Use Therapeutic Food (RUTF) and is used for treatment of severe acute malnutrition. It is suitable for people suffering from severe acute malnutrition or moderate acute malnutrition from age of 6 months. 0.2 Development of this Tanzania standard was necessitated by the need to ensure the safety and quality of ready to eat food for people with malnutrition being produced and or marketed in Tanzania. 0.3 In reporting the result of a test or analysis made in accordance with this standard, if the final value observed or calculated, is to be rounded off, it shall be done in accordance with TZS 4 (See clause 2). 1.0 Scope This Tanzania standard specifies requirements, methods of test and sampling for ready to eat food for people with severe and moderate acute malnutrition from age of 6 months. 2.0 References For the purpose of this Tanzania standard the following references shall apply: 1.

The food does not need cooking, or any other process before feeding. 3.3 Severe acute malnutrition (SAM) is defined by a very low weight for height (below -3z scores of the median WHO growth standards), by visible severe wasting, or by the presence of nutritional oedema. 3.4 Moderate acute malnutrition (MAM), also known as wasting is defined by a weight for height indicator between -3 and -2 z-scores (standard deviations) of the international standard or by a mid-upper arm circumference (MUAC) between 11 cm and 12.5 cm. 3
