Listeria Monocytogenes as Contaminant of Food Derived from Animal (Foodborne Disease) Tati Ariyanti
WARTAZOA, Indonesian Bulletin of Animal and Veterinary Sciences Vol 20, No 2 (2010): JUNE 2010
Publisher : Indonesian Center for Animal Research and Development

Listeria monocytogenes often contaminates food derived from animal and serves as pathogenic bacteria for animals and human. The outbreaks were related with the consumption of food derived from animals such as meat, milk, egg, seafood and its product that poorly cooked. Human listeriosis could be transmitted by direct contact with infected animal. The disease often is asymtomatic and widely distributes in the world. The mortality rate reaches to 30%. The bacteria is important because of the widespread in the environment, tolerant to acid, hot or salt environments, forms a biofilm layer and produces virulent factor (listeriolisin O/LLO). The bacteria can grow at 4°C or in the frozen food. Appropriate handlings of animals and their products are important to prevent from L. monocytogenes contamination. Key words: Foodborne disease, L. monocytogenes, food derived from animal, listeriolisin O

Free pathogenic microorganism of food derived from animals is a prerequisite for human consumption . One of the important pathogenic microorganisms originated from animal product of food is Salmonella. Salmonella enteritidis is frequently found in chicken and spreads vertically as well as horizontally products (eggs, meats and meat products) by direct or indirect contact. Salmonella that contaminated animal product of food can cause foodborne disease in human . Foodborne disease associated with Salmonella occurred in some parts of the world including Indonesia . This problem needs attention from the government, producers and consumers. In the animal production especially chicken, it is demanded to provide animal food and their products free from Salmonella . This is an important indicator of safety food condition . Salmonella control programs in the animal production level begin with raising free-Salmonella day old chick with free Salmonella feed, good farm environmental sanitation . Further more, the monitoring program of Salmonella in farm and post harvest process needs to be conducted . Appropriate handlings of animals and their products are important to obtain food of animal products that are healthy and safe for human consumption . Key word: Salmonella enteritidis, contamination, meat, egg

Food Safety of Animal Products That Viewed from Disease Aspect Supar .; Tati Ariyanti

Animal diseases are tnajor factors affecting food producing anitnals at husbandry productions. The infectious and or non infectious diseases can influence the food quality of animal products and their safety for human consumption. The food safety of animal products becomes a world trade issue because it affects some aspects of human life quality and health. The food safety of anitnal products is defined at least by physical and health conditions of animal at preharvest period . It can be achieved by good manufacturing practice, beginning at animal production level up to the harvesting period. During this period, the animals must be protected against infection by pathogens of either bacteria, viruses or protozoa. linportant animal diseases which often cause problems during animal husbandry productions are anthrax, salmonellosis, brucellosis, tuberculosis, clostridiosis. colibacillosis, staphylococcosis. Some of the pathogens causing those diseases may also cause food poisoning and foodborne disease. The viral disease infection can affect food-safety at preharvest time but not at postharvest. At prcharvest period in fanns the disease can be controlled by vaccines and selected drug application. To obtain the good quality assurance of food producing animals and the safety for human consumption, the physical and the health conditions of animals can be determined visually. To determine the health status of food producing animals, each animal must be tested for the presence of pathogens and or specific antibody. This needs a veterinary laboratory facility with good equipments, chemical and diagnostic reagents. On the other hand, in order to pursue the good quality assurance of food producing animals up to the harvesting period, the hazard analysis critical control point (HACCP) and good agricultural practice (GAP) concepts in animal husbandry productions must be followed. Key words: Animal products, preharvest, human consumption, food safety

Molecular Characterization of Pasteurella multocida: Its Implication with Epidemiology and The Development of Local Isolate Vaccines Supar .; Tati Ariyanti

Pasteurella multocida strains are the causative agents of pasteurellosis attacking wide range domestic and wild animals. The important pasteurellosis in animals in Indonesia are Haemorrhagic septicaemic (HS) or Septicaemia epizootica (SE) in large and small ruminants, fowl cholera in poultry and water powls. HS associated with P. multocida in large ruminants was controlled by killed whole cell vaccines produced by the use of P. multocida Katha strain, whereas fowl cholera was controlled by antimicrobial drugs. At present, there are only a limited molecular biology techniques have been applied to investigate P. multocida isolates from different geographic locations in Indonesia. Genomic DNA of P. multocida from HS cases from various provinces which were treated with restriction endonuclease ApaI and analysed by means of pulsed-field gel electrophoreses (PFGE) demonstrated the presence of high degree distinctive DNA pattern compared to that of the vaccine (Katha) strain from Burma and other reference strains. Similar different patterns were found in genomic DNA of local P. multocida isolates from cholera disease of chicken and ducks. P. multocida isolates from some provinces showed different DNA patterns to each other. These DNA pattern differences were probably associated with the alteration of their pathogenicity, antigenicity and immunogenicity, but it has not been confirmed yet. Vaccines prepared from P. multocida isolate originated from local HS cases and local cholera demonstrated better protection in experimental animals against heterologous and homologous challenges, in terms of higher and consistency antibody responses compared to that of Katha strain or imported P. multocida poultry strains. This supports the potential aspects of molecular characterization of local P. multocida isolates kept at the BCC Unit. These isolates may play an important role in developing local master seeds to produce pasteurellosis local vaccines which would be more promising to be used in Indonesia in the future but further field trials are still needed.

The Control of Infectious Coryza in Chicken Tati Ariyanti; Supar .
WARTAZOA, Indonesian Bulletin of Animal and Veterinary Sciences Vol 17, No 4 (2007): DECEMBER 2007
Publisher : Indonesian Center for Animal Research and Development

Infectious coryza or infectious snot is a disease caused by Haemophilus paragallinarum (HPG), that infects upper respiratory tract of either layer or broiler chickens or other poultry raised under small and large farm conditions. Infection on growing chicken caused reduction of weight gain, whereas in adult layer chicken caused decreasing egg productions, and hence significantly caused economic losses in poultry industries. Coryza cases in the farms are difficult to control by antibiotic treatments. Control by vaccination programmes using appropriate vaccines are the only ideal method, but vaccination failure using trivalent of classical serovar A, B and C of H. paragallinarum products from USA and European countries still occurred. This might probably due to the presence of new serovar B and C raised in the poultry farms in the fields, of which their antigenicity, immunogenicity and also immunoprotection of classical coryza vaccines are different from the new serovar in the fields. Research on coryza conducted at the Indonesian Research Center for Veterinary Science during the last 2 decades, resulted in some HPG isolates (belong to the classical serovar A, B or C) and these isolates were kept at the Bbalitvet Culture Collection (BCC) Unit. Studies on local isolate of HPG vaccine productions had been conducted to determine their efficacy in experimental chickens. At the same period, it was reported from Latin America and South Africa countries that new serovars B and new serovar C were found in that regions. These new serovars B and C were identified different to that of the classical serovar B or C antigenicity and immunogenicity which lead to the failure of coryza vaccination with classical serovar A, B and C imported from USA and Europe. These retrospective studies recommend that coryza is an important disease in poultry industries in this country causing a signifinant economic losses which need to be controlled properly. Further research is needed to measure the effectiveness of local isolate vaccines. Surveillance must also be conducted in order to anticipate the emerge of new HPG variant, therefore a new type of vaccine could be developed accordingly using recent local isolate.

This study aims to detect leptospirosis serologically and serovars found in cattle in the Sukabumi and Cianjur areas. 165 cattle serum samples were taken randomly in the Sukabumi and Cianjur region. Microscopic Agglutination Tests (MAT) were used for serological testing using the antigens of Leptospira serovar Icterohaemorrhagiae, Javanica, Celledoni, Canicola, Ballum, Pyrogenes, Cynopteri, Rachmati, Australis, Pomona, Grippotyphosa, Hardjo, Bataviae, and Tarassovi. The MAT results showed that positive serum leptospirosis in cattle in Sukabumi region was 18.75%, with serovars Hardjo 16.25%, Tarassovi 1.25%, and Hardjo and Tarassovi (1.25%). Meanwhile, in Cianjur region, positive serum was 30.60% with serovar Hardjo 22.35%, Tarassovi 2.35%, Icterohaemorrhagiae 1.18%, Grippotyphosa 1.18%, Hardjo and Tarassovi 1.18%, Cynopteri and Hardjo (1.18%), Rachmati, Pomona, Bataviae and Tarassovi (1.18%). Leptospira serovar Hardjo was the dominant serovar in both regions. Overall, one serovar was detected in 22.42% of cattle, two serovars in 1.82% and four serovars in 0.61% cattle.
