| Abstract | ||
| Thirty two sample for 8 different food types were collected from domestic market in Tikrit city . Sample were taken at random manner from street vendor and market in different places at different time . the sample were kept in Laboratory refregerater until they are tested. The Objective of the study were for the detection of microbiological and chemicale quality Paramaters. The rsults showed that the food samples that have been studied had containing bacteria of intestinal is limited to the rang in of between 73× 310 - 44× 710 (C F U / g), while the preparation of bacteria in the Staphylococcus aureus sandwiched ranging between 128× 310 – 23× 710 (C F U / g), And also been diagnosed with a number of intestinal bacteria prevailing in these foods, which include E.coli ,Salmonella,and Staphylococcus aureus More over, the results of the food sample that have been studied ,which were divided in to 4 food groups . Were study the levels concentration of four heavy elements ( Lead pb; Cadmium Cd; and Aluminum Al) .The concentration of the lead in these group of food are ranging from 0.195 - 0.434 (ug / g), while the concentration of Cadmium ranging from 0.153 - 0.266 (ug / g), while the concentration of Aluminum is between 1.021 - 3.022 (ug / g), it was noted that the concentration of each component of lead and cadmium were more highest in the group, of the Vegetable , and aluminum was more highest in the group of the Sweet ,The results also showed that the microbial contents and the heavy metals concentration for the evening samples were high than the concentrations of these parameter in the morning samples. This may be due to the effects of the accumulation values of the samples interval time | ||
