Blood from livestock is a common by-product which is obtained in industrial slaughterhouses. Blood is mainly composed of three fractions, red blood cells (RBCs), white blood cells (WBCs) and plasma. Plasma contains about 8% proteins, which is mainly composed of albumin, globulins and fibrinogen. Hemoglobin is the major protein within whole blood including RBC. These proteins isolated from animal blood have been used in variety of industry such as food, medical, pharmaceutics, animal feed and laboratory. Initially, blood is sterile in healthy animals thus adequate blood collecting system helps to minimize the risk of contamination. In Europe, closed-draining systems are adopted and a high-quality blood product is produced. European Union lays down health rules as regard animal by-products and derived products called Regulation (EC) No 1774/2002 which is improved to No 1069/2009. This regulation lays down strict animal and public health rules for the blood collection, transport, storage, handling, processing and use or disposal of all animal by-products. In spite of the significant using of blood from livestock, almost blood from slaughtering is considered a waste except only small part for use and causes a serious environmental pollution in Korea. Because of the environmental pollution by blood from slaughterhouse, the great expense is loosed, and blood-related products are small and are imported from foreign countries in Korea. For successful blood utilization, suitable infrastructure facilities are needed to control microbial contamination of blood from slaughterhouses and more specific plans on animal blood control may be established at the same time.

This study was carried out to investigate the prevalence and antimicrobial resistance patterns of Campylobacter jejuni isolated from duck feces. In total, 112 (32.9%) isolates of C. jejuni were identified from 430 duck feces samples from September to December, 2010. All isolates were susceptible to telithromycin, whereas majority of the C. jejuni isolates were resistant to azithromycin (18.8%), ciprofloxacin (86.6%), erythromycin (0.9%), gentamicin (15.2%), tetracycline (80.4%), florfenicol (3.6%), nalidixic acid (87.5%), clindamycin (7.1%). As a result, appropriate protocols for antimicrobial agents and strategies to reduce antimicrobial resistance will be needed in the future.
