Statistical analysis of data of number of sampling points for microbial counts representing the entire go~t/sheep carcass was carried out. Thirtytwo sampling points were evaluated out of which fourteen were found to represent the entire dressed carcass for assessing its hygienic efficacy.
,Slaughter hall facilities in India are far from satisfactory. Modern well managed abattoirs are being established for hygienic slaughtering and for proper utilization of slaughter house by-products.The surface bacterial load of a carcass is one of the criteria for assessing, hygienic conditions of a slaughter hall, quality of meatlmeat products at various stages of processing1, men, equipment and environment coming in its contact2. The estimation of bacterial numbers on meat, poultry, and other foods and the need of standardized techniques has been emphasized by various w0rkers.3-~ An evaluation of representative sampling points for beef carcass has been made by Kneadg. Similar studies in the case of sheep and goat carcasses have not been reported in India. The aim of the present study was to determine the minimum number of sampling points for microbial population in the carcass which could adequately represent the microbial load on the entire goatlsheep carcass.
E X P E R I M E N T A L P R O C E D U R EThe investigations were carried out at AFD Meat Packing Plant.Four Rajasthani sheep and four Jamunapari goats in the age range of 34-4 years and conforming to ASC specifications were selected at random from 700 animals for slaughter. The sequence of slaughter operations upto dressed carcass described earlier2 was followed.The dressed and washed carcass was divided into thirtytwo sampling sites representing evenly all the wholesale cuts as shown in Fig. 1. The thirtytwo points were distributed as twenty in the exterior region and twelve in the interior region. Out of twenty points ten were on the left and ten on the right side. ' Similarly in the interior region six points lay to the left and six points on the right. The following pairs denote the identical points on the left and right side of the carcass.
Abstract. The unsteady flow of an incompressible viscous fluid with a uniform distribution of dust particles between two parallel plates when one of which is impulsively stopped from the state of uniform motion is studied. Analytical expressions for velocities of the fluid and dust particles have been obtained. It is found that the dust particles slip on the wall which is brought to rest impulsively instead of sticking to it; on the other hand, they stick to the stationary plate. The slip-velocity of the dust is noticed to be decreasing as the physical time increases and the relaxation time of the dust particles decrease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
