Foodborne disease is a disease caused by contaminated food. Chicken meat is very susceptible to contamination by bacteria. Escherichia coli, Salmonella sp, and Staphylococcus aureus are types of bacteria found in chicken meat. The purpose of this study was to see how many Escherichia coli, Salmonella sp, and Staphylococcus aureus colonies in raw chicken meat in traditional markets in Surabaya City. The research sample used was 30 samples of chicken meat taken in 5 traditional markets in Surabaya. Six chicken meat sellers were taken with 1 sample and put in the sterile tube from each market. The test was carried out using the Total Plate Count (TPC) method. The TPC test results showed that all samples were contaminated with E. coli, with the most colony being 2.2X10-7 CFU/g while the minor colony was 5X10-4 CFU/g. There are two samples contaminated with Salmonella sp, in the G market and the W market, with code D6 4.7X10-6 CFU/g and code E5 1X10-6 CFU/g. Meanwhile, S. aureus was only found in the W market with sample codes E1 & E6, and each sample had a colony of 2.7X 10-7 CFU/g and 2X10-5 CFU/g.

The changes in microbiological and chemical parameters during the fermentation and ripening of sheep cheese were observed. The cheese was produced from raw sheep’s milk at different temperatures on the sheep farm. The following parameters were determined: total plate count, coliform count, Staphylococcus aureus count, pH value, titrimetric acidity, and the amount of lactic acid. As our results indicate, the fermentation at temperatures of between 18–22°C reduces the number of undesirable micro-organisms due to the presence of lactic acid being produced by lactic-acid bacteria. During the fermentation at lower temperatures (below 18°C) the amount of lactic acid is insufficient, and the undesirable microorganisms can survive.

This study aimed to evaluate the Total Plate Count and total Staphylococcus aureus count of beef sold in wet markets in Mulyorejo sub-district below the National Standard Indonesia (SNI 7388:2009) about maximum limit of microbial contamination in food or not. Total of twenty four samples of beef purchased from traditional markets of Tempurejo, Krempyeng Yamuri, Pacar Keling, and Menur in Mulyorejo sub-district Surabaya were examined by Total Plate Count using pour plate method. The sample was also cultured in Mannitol Salt Agar. The colony suspected to be S. aureus were taken for identification. The identification of S. aureus consists of isolation in Mannitol Salt Agar, Gram staining, catalase test, and coagulase test. Total plate count result showed that four samples were exceeding the National Standard of Indonesia SNI 7388:2009 or 1x106 CFU/g and the rest were below the maximum Total Plate Count in SNI. The highest Total Plate Count result was 1,9x106 CFU/g and the lowest was 7,8x104 CFU/g. The result of identification showed that 100% samples examined were contaminated by S. aureus with the highest result was 2,9x104 CFU/g and the lowest result was 4,3x103 CFU/g or exceeding the SNI 7388:2009.

Food preservation is very important for the quality and safety of the meat and its product. In present study, the fresh beef were storaged in three different conditions, which including superchilling (-1 °C), chilled (4 °C) and frozen (-18 °C) preservation, respectively. The pH value, total plate count, thiobarbituric acid-reactive substances value (TBARS), total volatile basic nitrogen (TVB-N) and color were also determined. The result showed that after 8 days storage, the chilled beef decayed seriously, the frozen beef had no conspicuous changes, and the beef under supperchilling condition could extend the shelflife to 20 days and also maintained higher quality. To some extent, superchilling storage represent an advantage over traditional chilled and frozen storage, it is a good way to preserve freshness of fresh products and the raw material before processing, and also could have great effect on improving the quality characterizes of beef and prolong its shelf life.

Raw chicken meat was comminuted and homogenised. There were measured water activity and pH (aw = 1 for temperature 25°C, pH = 5.8 for temperature 8°C). Input raw material was investigated for the presence of Listeria monocytogenes (negative) and the raw meat was inoculated by Listeria monocytogenes CCM 4699. Number of Listeria monocytogenes, total plate count and number of coliforms were determined in the range 0–7 days by bacteriological survey for the storage temperatures 4.9, 7 and 8.3°C. The increase of Listeria monocytogenes counts has been registered for temperature 4.9°C about log 1.5 CFU/g after 6 days, for temperatures 7 and 8.3°C about 2 log CFU/g (regarding to the starting counts). The prediction for listeria growth with the aid of Food MicroModel was also made. The best agreement between the experimentally analysed number of bacteria and prediction was received for the lowest incubation temperature 4.9°C.
