A low level of sanitation and hygiene applied by smoked fish processors in North Sulawesi can affect the quality and safety of the product itself. Interestingly, there is a huge market demand of smoked fish product in North Sulawesi. That is why  it is necessary to improve quality of smoked fish product by assisting the smoked fish processors. The program's target partners are located in Pontoh Village, Wori District, North Minahasa Regency which is geographically located on the coast Pontoh Village is categorized as a fishing community, which is about 50% classified as poor families and has a small business group of processing smoked fish. The aim of this program is to increase production, marketing and finance for small entrepreneurs in Pontoh Village, Wori District, North Minahasa Regency so they can be skilled and economically independent. The specific target of this activity is to produce smoked fish products that are superior in terms of taste and shelf life while providing business continuity and strong management. The method of implementation that will be applied to this program are 1) Training on how to produced smoked-fish product using good manufacturing practices  2) Assiting about sanitation and hygiene in every step of producing smoked fish; 3) Advising on management

ABSTRACT The prevalence and numbers of Listeria monocytogenes in various categories of ready-to-eat (RTE) food products taken from retail outlets and food industries over a 5-year period are presented. A total of 30,016 RTE food samples were analyzed for L. monocytogenes prevalence, and 3.6% were found to be positive. The highest prevalence was found for RTE fish and fish products (11.6%), especially for lightly salted and cold-smoked fish products. The overall prevalence of L. monocytogenes in other food categories was low, within the range of 0 to 3.9%. In addition, 14,342 RTE food samples were analyzed to determine the numbers of L. monocytogenes. A food safety criterion of 100 CFU/g was exceeded for 0.3% of RTE food samples. Samples most often exceeding the legal safety limit were from the RTE salted and cold-smoked fish product categories. High prevalence, 28.6 and 26.5%, respectively, and high numbers of L. monocytogenes among salted fish and cold-smoked fish products indicate a risk of listeriosis, especially for susceptible risk groups. The results of the current study can be used at both the national and the international levels to update the perception of the L. monocytogenes risk deriving from RTE foods. HIGHLIGHTS

Carnobacterium Piscicola

Data on the prevalence and growth of Listeria monocytogenes in lightly preserved fish products from subtropical and tropical regions are very scarce. Our research describes L. monocytogenes that was detected in 5% of the packages of cold-smoked surubim, a native Brazilian freshwater fish that we analyzed, and shows that the strains isolated were of the same random amplified polymorphic DNA subtype as the strains that were isolated from the same factory 4 years earlier. A bacteriocinogenic strain of Carnobacterium piscicola (strain C2), isolated from vacuum-packed cold-smoked surubim, and two C. piscicola strains, isolated from vacuum-packed, cold-smoked salmon, were capable of limiting or completely inhibiting the growth of an L. monocytogenes (strain V2) isolated from surubim in fish peptone model systems incubated at 10°C. Mono-cultures of L. monocytogenes reached 108 CFU/ml (g), whereas the growth of L. monocytogenes was completely inhibited by C. piscicola C2. The bacteriocinogenic C. piscicola A9b+ and its nonbacteriocinogenic mutant A9b− reduced maximum Listeria levels by 2 to 3 log units. Both bacteriocinogenic C. piscicola strains prevented listerial growth in cold-smoked fish juices (surubim and salmon). Although the carnobacteria grew poorly on cold-smoked surubim at 10°C, the strains were able to reduce maximum Listeria counts by 1 to 3 log units in an artificially inoculated product (surubim). We conclude that Brazilian smoked fish products harbor L. monocytogenes and should be stabilized against the growth of the organism. C. piscicola C2 has the potential for use as a bioprotective culture in surubim and other lightly preserved fish, but further studies are required to optimize its effect.

AbstrakKecamatan Rowosari memiliki potensi perikanan yang sangat baik karena didukung oleh letaknya yang strategis dan berbatasan langsung dengan Laut Jawa. Produk ikan laut ini dimanfaatkan oleh warga Desa Tambaksari yang diolah menjadi produk ikan asap. Proses pengasapan yang masih sederhana dan belum tersentuh teknologi ini sehingga kapasitas produksi yang sedikit dan kurangnya higienitas pada proses pengasapan. Proses pengasapan ikan yang memerlukan waktu 7 – 8 jam serta hasil ikan asap yang terpapar di rak terbuka membuat produk ikan yang dihasilkan kurang higienis karena lalat dapat hinggap pada ikan tersebut. Untuk itu diperlukan teknologi yang dapat meningkatkan kapasitas dan higienitas produk ikan asap yaitu dengan sistem paparasi. Dengan sistem paparasi proses pengasapan dapat ditekan hingga 3 – 4 jam serta tingkat higienitas yang lebih baik. Kata kunci: Pengasapan Ikan, TerintegrasiImprovement Of Quality And Capacity Of Asap Fish Production Through Paparation System (Integrated Finging) In Tambaksari Village, Rowosari District, Kendal Regency, Central Java AbstractRowosari District has excellent fishery potential because it is supported by its strategic location and directly adjacent to Java Sea. This marine fish product is utilized by Tambaksari villagers who processed into smoked fish products. The fogging process is still simple and untouched by this technology resulting in little production capacity and a lack of hygiene in the curing process. The process of fumigation of fish that takes 7 - 8 hours and the results of smoked fish exposed on the open shelves make fish products produced less hygienic because the flies can land on the fish. For that needed a technology that can increase the capacity and hygiene of smoked fish products with the system of paparasi. With curing process paparasi process can be pressed up to 3 - 4 hours and hygiene level better. Key words: Fish Smoking Kiln, Integration

Cold smoked salmon products (belly flaps, pieces, fillet, and loin) obtained from the retail market in Lithuania were tested for the presence of L. monocytogenes. It was found that contamination of the cold smoked fish products with Listeria spp. depends on the type of the product. Contamination with listeria in salmon belly flaps was 7.5 times higher than in the loin (P<0.05), 1.8 times higher than in the pieces (P<0.05) and 30 times higher than in the fillet (P<0.05). Microbiological analysis showed that 32.5% (P<0.05) of the fish product samples were infected with L. monocytogenes, while multiplex PCR confirmed 31.25% positive samples (P<0.01). According to the study results, L. monocytogenes strains were divided into two serotypes: 4b (94.6%) and 1/2a (5.4%). High contamination of the products with Listeria spp. showed that cold smoked salmon products, sold in local market, can be a reason of human listeriosis in Lithuania.
