Abstract

The poultry feed, meat and egg samples were collected from the major poultry raising areas of the country to know the presence of heavy metals especially arsenic (As), lead (Pb) and chromium (Cr). A total of 360 elemental samples for As, Pb and Cr were analyzed in the laboratory. The heavy metal contents (As, Pb & Cr) of all the tested samples were found positive. But, the levels were below the Maximum Permitted Concentration (MPC) in most cases. The layer and broiler ready feed samples found safe from those elements; On the other hand, the “Cr” and “Pb” content in 14% and 11% loose feed samples were 7-70 and 3 times respectively higher than that of MPC. Notes worthy, the egg samples were also found safe from those elements. Of the tested samples 14% broiler meat and 50% spent hen samples found slightly higher level of “As” and 4-6 times “Cr” respectively than the MPC. In conclusion, the poultry farmers are suggested to buy poultry feeds from the reputed feed company and discourage to use loose feeds. Moreover, feed marketing channel particularly loose feed marketing should be monitored properly by the regulatory authority. Asian Australas. J. Food Saf. Secur. 2018, 2(1), 1-5

Food safety has become an integral part of the relevant production processes to meet the strongly negative reactions of consumers and consumer’s organizations to recent crises in the food- animal industry (Mulder, 2011). He mentioned that truly safety products are free from microorganisms that are pathogenic to man and without any residues of substances used in primary production, including antibiotics and other chemicals, or foreign bodies
Materials and Methods In order to get real scenario about the presence of heavy metals content in poultry feeds, meat and eggs; samples were collected from major poultry rearing areas of the country e.g. Dhaka (Savar, Dhamrai, Gazipur), Chittagong and Sorupkati, Pirojpur

Summary

Introduction

Food safety has become an integral part of the relevant production processes to meet the strongly negative reactions of consumers and consumer’s organizations to recent crises in the food- animal industry (Mulder, 2011). Sarker et al (2011) mentioned that inappropriate use of antibiotics or other foreign substances is undesirable for residues which may produce toxic or allergic reactions in susceptible individuals who eat meat or egg that contains residues. Metals such as Fe, Cu, Mg, Co, Zn are essential for human body but chronic metabolic disturbances may occur due to the deficiency or excess of these metals. Since the poultry products (egg and meat) comparatively cheaper and available; a wide range of consumers intake the poultry
