Abstract

Nowadays, the consumption of meat and meat products in different countries varies considerably based on social, economic, and geographical differences. Meat and meat products are the most important sources of protein. This study aimed to investigate the possibility of unauthorized tissues in sausage products in Tabriz and Khoy by histotechnique. For this, 80 sausages samples with ≤ 55% and > 55% 55% meat content were collected (from January to March of 2015). For histological evaluation, the slides were stained with Hematoxylin and Eosin. Based on results, in 87.5% of the samples, cartilage tissue with a high percentage was observed. Unauthorized tissues types such as glands, connective tissue, fat, skin, cartilage, bone, trachea, lung, bladder, parasite eggs, and intestine were observed. The presence of unauthorized tissues in most samples may reduce consumers' desire to use sausages. Consequently, there is a necessity for efficient control at the regional level by authority organizations.
