A study was conducted mainly to assess the microbiological quality of different brands of hotdogs sold in Silang Market as well as to identify potential pathogens present in Hotdogs. ' By means of spread plate method, various media like Plate Count Agar (PCA), Eosin Methylene Blue (EMB), Violet Red Bile Agar (VRBA), MacConkey Agar (MCA), Salmonella-Shigella Agar (SSA), and Cereus Selective Agar (CSA) were used to asses the microbial quality of different brands of Hotdogs. Result showed that in total plate count, the highest microbial count was on sample V which was 3.57 x 105cfu/g and the lowest was sample TJ that obtained 2.45 x 105cfu/g. In terms of coliform count on EMB, sample V obtained the highest microbial count of 8.99 x 105cfu/g and the lowest was sample TJ which recorded a 1.8 x 105cfu/g microbial count, on MCA the Sample V and Sample TJ, obtained the highest ( 17.09 x 105cfu/g) and lowest (1.98 x 105cfu/g) microbial count, respectively. On VRBA, sample C and S obtained the highest count of 4.6 x 105cfu/g and sample TJ obtained the lowest count which was 2.36 x 105cfu/g. On the other hand, sample C and sample TJ obtained the highest (5.25 x 105cfu/g) and lowest (3.12 x 105cfu/g) microbial count, respectively. On Salmonella-Shigella count, sample C obtained the highest microbial count of 2.09 x 105cfu/g and sample TJ obtained the lowest count of 0.68 x 105cfu/g. Lastly, the spore count recorded the highest (1.57 x 105cfu/g) microbial count on sample C and lowest count of 0.7 x 105cfu/g on sample TJ.
Staphylococcus aureus (77), Shigella sonnei (64) and E. coli (49) were identified
as the leading bacteria present in different brand of hotdogs.
