Innards parts are more widely consumed by the public than the muscle parts, or more commonly known as beef. People are aware that the innards contain a lot of cholesterol, but they don’t know about the heavy metal content. This research aims to study lead contamination levels in offal and beef muscle contaminated with lead. A total of five cows with known lead contamination slaughtered to be checked for the levels of lead. Viscera taken part include the liver, lungs and intestines, which are the commonly consumed part. While part of muscle taken from the costae muscles, is the part with most blood flow. Levels of lead in innards and muscles were checked using atomic absorption spectrophotometry (AAS) method. Result of the examination of lead content on innards were obtained that is liver = 0.76 ± 0.25 ppm; Lung = 1.11 ± 0.08 ppm; intestinal = 0.90 ± 0.29 ppm; and muscle = 0.69 ± 0.13 ppm respectively. This research indicated that innards parts contain more lead than the muscle parts. Thus it can be concluded that the muscle part is safer for consumption than in the innards. It is suggested that there’s the need for random checks in innards and beef sold in the market, especially for the presence of lead.
