Incidence of faecal streptococci as an indicator of sanitation in ice-cream and frozen vegetables

WOS: 000174917000002Fifty-three ice-cream and fifty-five frozen vegetable samples, collected from two different factories, were analysed for total coliform bacteria, faecal coliform bacteria and faecal streptococci so that the value of faecal streptococci as an indicator of faecal contamination and sanitation in ice-cream and frozen vegetables could be evaluated. Thirty-two per cent of the ice-cream samples and 73% of the frozen vegetable samples were positive for coliform. bacteria, whereas only 4% of the ice-cream samples and 24% of the frozen vegetable samples contained faecal coliform bacteria. Occurrence of faecal streptococci in the ice-cream and frozen vegetable samples were 81 and 75%, respectively. These results indicate that there is no direct relationship between the presence of faecal coliforms and faecal streptococci, and the high occurrence of faecal streptococci in frozen foods examined suggests that faecal streptococci is a better sanitary indicator in frozen food products

The Effect of Nitrite, Garlic and Starter Culture on the Survival of Salmonella-Typhimurium In Turkish Soudjuk

WOS: A1993KQ34500014The effects of nitrite, garlic and starter cultures on the survival of Salmonella typhimurium were evaluated during manufacture and storage of Turkish soudjuk. Sodium nitrate (0.2 g kg-1) and garlic (8 g kg-1) added to the sausage did not have any significant effect on the survival of S typhimurium. The use of a commercial starter culture had a pronounced effect on the survival of the test organism. An initial inoculum of 2.5 x 10(5) g-1 S typhimurium cells decreased to an undetectable level within 12 days of the ageing period when the starter culture was used

Ultrasound in the meat industry: General applications and decontamination efficiency

WOS: 000350781500008PubMed ID: 25613122This review summarizes the findings of research focused on ultrasound as a "green", nonchemical technology in the meat industry to improve meat quality and safety. An overview of the importance of the decontamination in meat processing and microbial inactivation using ultrasound combined with some other applications is provided along with results of high power ultrasound studies which have been applied and adapted in the meat industry. The research results revealed that ultrasound by itself or in combination with other processing and/or preservation methods has a potential for improving the general quality, marination and tenderness of meat, preventing microbial growth and recontamination in meat and meat products as well as for the determination of defects in carcasses and cleaning process equipment. This review will provide an interpretation of ultrasound applications, an up-to-date summary of published articles, and an overview of the microbial inactivation in meat and poultry and their products by ultrasound. Since there is a need for not only a pathogen-free product but also a quality product; this review also can be accepted as a report on the results of research in the field of meat quality improvements with ultrasound applications.
