For powdered infant formula (PIF) the absence of Enterobacteriaceae in 100 g is required. Nevertheless, occasionally Enterobacteriaceae can be detected. A recent study concentrated on the occurrence of a specific foodborne pathogen out of the Enterobacteriaceae family, Cronobacter spp., in PIF manufacturing facilities in order to investigate clonal persistence and identify possible transmission routes. The aim of this study was to genotype isolates from frequently found other species within the family of Enterobateriaceae in order to elucidate and trace back transmission routes not only limited on Cronobacter spp. In total 216 isolates from three different species (Enterobacter (E.) cloacae, Klebsiella (K.) pneumoniae and Leclercia (L.) adecarboxylata) were genotyped. The isolates originated from raw ingredients, environment and products of an infant formula processing plant. Restriction digest with Xbal revealed discriminative PFGE patterns consisting of 10-20 bands for all three species. Heat sensitive additives could be traced back as contamination source for products. Furthermore, the production environment was found as a reservoir for persisting strains. Showing analogy to the situation described for Cronobacter spp., especially E. cloacae that can be found in the same niches as Cronobacter spp. but more frequently might therefore be used for hygiene monitoring along the processing chain. Certain genotypes of E. cloacae, that are able to persist within the factory environment, might possess special properties as e. g. enhanced desiccation tolerance enabling them to survive the harsh environmental conditions.","PeriodicalId":8255,"journal":{"name":"Archiv Fur Lebensmittelhygiene","volume":"382 1","pages":"128-131"},"PeriodicalIF":0.0,"publicationDate":"2010-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80704977","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The control of these organisms during the processing of infant formula and identification of possible contaminating sources is of importance to manufacturers. In this study, infant formula processing sites were monitored for the presence of Cronobacter spp. (E. sakazakii) in 2007. Cronobacter were isolated using ISO/TS 22964 and simultaneously using a newly developed differential method, Cronobacter Screening Broth (CSB). Clonal types of Cronobacter strains in the environment, raw materials, and products were investigated using PFGE and RAPD in order to shed light on the possible dissemination routes within the facility. Over the course of the study, a total of 153 Cronobacter isolates were obtained from 46 end-products, 23 raw materials and 44 environmental samples. The 153 Cronobacter isolates represented 71 PFGE pulso-types, with 24 pulso-types containing multiple isolates. Clonal isolates present in products could be matched to indistinguishable pulso-types in raw materials and in the environment, however no strains were identified that were present in both the environment and raw materials. Although the majority of the isolates were obtained from products, the largest diversity of isolates was observed in raw materials. This may indicate raw materials as a significant source of Cronobacter entry into the production facility with subsequent selection for strains that are able to persist within the factory environment.","PeriodicalId":8255,"journal":{"name":"Archiv Fur Lebensmittelhygiene","volume":"22 1","pages":"66-72"},"PeriodicalIF":0.0,"publicationDate":"2009-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82329003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to study the implementation and potential problems in implementing food legislation, a questionnaire was sent to small- and medium-size meat and fish FBOs (n = 904) in Finland found in the register of the National Food Safety Authority Evira. The total response rate was 27.6%. In addition, 18 different FBOs that had gone through the process of approval for meat and fish establishments between 2005 and 2006 were interviewed.The results showed that FBOs in the meat and fish sector have both common and differing experiences of the problems caused by the food legislation requirements. Most common problems concerning food safety legislation are related to the layout of production premises and transport routes, control fees, requirements concerning in-house control, structures and maintenance of premises and varying interpretation of food safety legislation. Small FBOs saw the requirements of food legislation as more onerous than medium-sized FBOs. Small FBOs mentioned the requirements concerning in-house control and approval of the in-house control plan, labelling and traceability as problematic for their operations. On the other hand, medium-sized FBOs experienced problems relating to the requirements for building materials as such, by-products and waste management, in addition to layout of production premises and transport routes, structures and maintenance of facilities and the HACCP system.","PeriodicalId":8255,"journal":{"name":"Archiv Fur Lebensmittelhygiene","volume":"316 1","pages":"172-178"},"PeriodicalIF":0.0,"publicationDate":"2009-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77928201","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

STEC infections have also been associated with acidified or fermented products. This fact may indicate an increased acid resistance of STEC. In the present study, four pathogenic E. coli strains (STEC 0157:H7, STEC O26:H11, STEC O159:H - , EPEC 0157:H45) and a control strain (E coli K12) were examined for growth and persistence under hydrochloric, acetic and lactic acid stress. In the growth experiments, the 0157:H45 strain (hydrochloric and acetic acid) and the 0157:H7 strain (acetic acid) showed improved acid resistance, whereas no differences were evident for the other strains. In the survival experiments, significant differences were found between strains in the stationary and logarithmic growth phase. By comparison of the three acids, acetic acid proved to be most effective for growth inhibition and inactivation. The comparison of acid adapted and non adapted STEC O157:H7, STEC O159:H - and E coli K12 showed that strains adapted with hydrochloric acid exhibited improved acid resistance, but this effect was not confirmed after lactic acid adaptation. The adaptation with acetic acid improved the acid resistance of STEC O159:H - and E. coli K12, whereas that of STEC 0157:H7 was not affected. Consequently, remarkable strain-to-strain variation in the acid stress response of \"enteropathogenic\" E. coli was evident. This variation was rather influenced by the acid applied than by the serotype or the pattern of virulence factors of the strains.","PeriodicalId":8255,"journal":{"name":"Archiv Fur Lebensmittelhygiene","volume":"32 1","pages":"135-140"},"PeriodicalIF":0.0,"publicationDate":"2009-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86568441","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 90 listeriosis cases were identified for the period from 1998 to 2007. During the 10-year study period the overall incidence of listeriosis was 0.4 per 100 000 of the population. Overall, 77% of all described clinical cases were characterized by meningoencephalitis and/or sepsis. The overall mortality, including abortions and perinatal infant deaths, was 6.7% (6/90). A marked clustering of listeriosis cases was observed from September to December 2000 possibly indicating one large outbreak. The lack of serotyping and molecular typing methods for subtyping of Listeria (L.) monocytogenes isolates in the present laboratory-based surveillance system is one of the main reasons why there were no officially documented listeriosis outbreaks in Latvia up to the present date. Therefore, serotyping and molecular typing should be introduced for all clinical isolates of L. monocytogenes to identify any listeriosis outbreaks as early as possible. Such measures will allow the application of appropriate actions at the food industry level, thus either preventing or significantly reducing the real burden of listeriosis in Latvia.","PeriodicalId":8255,"journal":{"name":"Archiv Fur Lebensmittelhygiene","volume":"27 1","pages":"161-165"},"PeriodicalIF":0.0,"publicationDate":"2009-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81778502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
