This study was performed to investigate the contents of the heavy metals such as cadmium(Cd), copper(Cu), iron(Fe), lead(Pb) and zinc(Zn) in meat and meat products. For this experiment, each 20 samples of beef and pork were collected at slaughterhouse in Seoul areas and 45 samples of meat products(ham, sausage, processed meat and seasoned meat) were purchased from commercial food markets. The contents of the heavy metals was determined by atomic absorption spectrophotometry from Jan. to Nov. In 1998. The results obtained were summarized as follows ; 1. In Korean native beef, mean values of the heavy metals(mg/kg) were Pb : 0.14$\pm$0.10, Cd : 0.07$\pm$0.02, Cu : 1.73$\pm$0.95, Zn : 42.82$\pm$8.17 and Fe : 67.43$\pm$24.18, respectively. 2. In imported beef, mean values of the heavy metals(mg/kg) were Pb : 0.03$\pm$0.08, Cd : 0.06$\pm$0.02, Cu : 1.41$\pm$0.62, Zn : 42.93$\pm$4.95 and Fe : 40.06$\pm$12.77, respectively. 3. In pork, mean values of the heavy metals(mg/kg) were Pb : not detected, Cd : 0.09$\pm$0.02, Cu : 1.08$\pm$0.23, Zn : 19.49$\pm$6.02 and Fe : 30.21$\pm$10.51, respectively. 4. In ham, mean values of the heavy metals(mg/kg) were Pb : trace, Cd : trace, Cu . 1.19$\pm$0.46, Zn : 13.58$\pm$4.99 and Fe : 31.43$\pm$11.74, respectively. 5. In sausage, mean values of the heavy metals(mg/kg) were Pb : 0.15$\pm$0.34, Cd : 0.08$\pm$0.05, Cu : 1.15$\pm$0.46, Zn : 13.70$\pm$7.13 and Fe . 27.28$\pm$15.05, respectively. 6. In processed meat, mean values of the heavy metals(mg/kg) were Pb : 0.08$\pm$0.13, Cd : 0.09$\pm$0.04, Cu : 1.28$\pm$0.60, Zn : 14.72$\pm$7.09 and Fe : 24.04$\pm$10.33, respectively. 7 In seasoned meat, mean values of the heavy metals(mg/kg) were Pb : 1.05$\pm$2.21, Cd : 0.13$\pm$0.03, Cu : 1.06$\pm$0.16, Zn : 17.53$\pm$8.72 and Fe : 26.76$\pm$9.02, respectively.
