Bovine serum contains various nutrients and growth factors that can be potentially used in biological experiments, drug manufacturing process and food industry. However, almost all the bovine blood has been wasted during slaughter process in Korea, thus there is a high demand for alternative uses of the wasted sera. In order to produce high quality and safe sera, it is necessary to screen zoonotic pathogens as well as other microbial contaminants to prevent any downstream contamination. The present research has been undertaken to assess biological safety of Hanwoo sera by determining microbiological contamination during slaughtering and handling processes. Serological tests have been performed to detect bacteria, mycoplasma and virus contamination in total of 52 Hanwoo sera. No sera were found to be contaminated with mycoplasma or virus, but only two sera were found to be contaminated with Bacillus thuringiensis. The present result shows that Hanwoo sera obtained from slaughtering process are biologically safe and have potentials to be developed as a biological reagent. Moreover, the methods employed in our study may provide basic standard for microbiological screening methods once wasted Hanwoo sera gain industrial values.
