In: International food research journal: IFRJ, Band 30, Heft 2, S. 290-302

Abstract

The handling and slaughtering processes for animals have a significant effect on meat quality. Islamic (halal) slaughter and many different stunning methods are used in the meat industry worldwide. The objective of the present review was to update the current literature and practices concerning halal slaughter and stunning methods, and their effects on meat quality. The present review used inductive reasoning and comparison between halal and stunning methods for the slaughtering of farm animals. Halal slaughter involves cutting the carotid arteries, jugular veins, oesophagus, and throat without stunning. Halal slaughter facilitates the draining of blood from the animal, which is necessary to produce high-quality meat with good conservation and increased shelf life. On the other hand, most stunning slaughter hinders the bleeding process in sheep and goats. The retained blood content may act as a suitable medium for the growth and multiplication of different kinds of harmful microorganisms and make badly bled meat hard to preserve. Proper halal slaughter has several advantages regarding meat quality in comparison to stunning methods, and requires greater management attention pre-, during, and post-slaughtering to maintain good welfare and the production of high-quality meat.
