ISO 16649-3:2015 specifies a horizontal method for the detection and enumeration of β-glucuronidase positive Escherichia coli, by means of the liquid-medium culture technique and calculation of the most probable number (MPN) after incubation at (37 ± 1) °C, then at (44 ± 1) °C. This part of ISO 16649 is applicable to the following:- products intended for human consumption and the feeding of animals;- environmental samples in the area of food production and food handling.The method is suitable for the enumeration of cells of E. coli that might have been subjected to stress arising from dehydration, freezing, and exposure to a saline (such as marine) environment or damage by disinfectants such as chlorine-containing products.A limitation of the applicability of this part of ISO 16649 is imposed by the susceptibility of the method to a large degree of variability. The method is intended to be applied and the results interpreted in the light of the information given in Clause 11.This method has not been fully evaluated for all matrices (e.g. for milk and milk products). ISO 7251 is intended to be used for milk and milk products. |

SO 9308-1:2014 specifies a method for the enumeration of Escherichia coli (E. coli) and coliform bacteria. The method is based on membrane filtration, subsequent culture on a chromogenic coliform agar medium, and calculation of the number of target organisms in the sample. Due to the low selectivity of the differential agar medium, background growth can interfere with the reliable enumeration of E. coli and coliform bacteria, for example, in surface waters or shallow well waters. This method is not suitable for these types of water. SO 9308-1:2014 is especially suitable for waters with low bacterial numbers that will cause less than 100 total colonies on chromogenic coliform agar (CCA). These may be drinking water, disinfected pool water, or finished water from drinking water treatment plants.Some strains of E. coli which are β-D-glucuronidase negative, such as Escherichia coli O157, will not be detected as E. coli. As they are β-D-galactosidase positive, they will appear as coliform bacteria on this chromogenic agar |

ISO/TS 6579-2 gives a method for the enumeration of Salmonella spp. present in: products intended for human consumption and for the feeding of animals; environmental samples in the area of food production and food handling; animal faeces; and environmental samples from the primary production stage by calculation of the most probable number (MPN).The method is based on miniaturization of the dilution, pre-enrichment and selective enrichment steps. The selective enrichment medium, modified semi-solid Rappaport?Vassiliadis (MSRV), is intended for the detection of motile salmonellae and is not appropriate for the detection of non-motile salmonellae.It is possible that the method is less appropriate to enumerate Salmonella ser. Typhi and Salmonella ser. Paratyphi |

The method is not appropriate for the enumeration of Salmonella spp. in (very) low contaminated samples |

ISO 4833-1:2013 specifies a horizontal method for enumeration of microorganisms that are able to grow and form colonies in a solid medium after aerobic incubation at 30 °C. The method is applicable to: a) products intended for human consumption and for animal feed; b) environmental samples in the area of food and feed production and handling. ISO 4833-1:2013 is applicable to: 1) products that require a reliable count when a low limit of detection is specified (below 102/g or 102/ml for liquid samples or below 103/g for solid samples); 2) products expected to contain spreading colonies that obscure colonies of other organisms, e.g. milk and milk products likely to contain spreading Bacillus spp |
| Campo de Aplic.:
|
The applicability of ISO 4833-1:2013 to the examination of certain fermented food and animal feeds is limited and other media or incubation conditions can be more appropriate. However, this method can be applied to such products even though it is possible that the predominant microorganisms in those products are not detected effectively. For some matrices, the method specified in ISO 4833-1:2013 can give different results to those obtained using the method specified in ISO 4833‑2 |

ISO 4833-2:2013 specifies a horizontal method for enumeration of microorganisms that are able to grow and form colonies on the surface of a solid medium after aerobic incubation at 30 °C. The method is applicable to: a) products intended for human consumption or for animal feed; b) environmental samples in the area of food and feed production and food handling |
| Campo de Aplic.:
|
ISO 4833-2:2013 is applicable to: 1) products containing heat-sensitive organisms that are likely to form a significant proportion of the total flora (e.g. psychrotrophic organisms in chilled and frozen foods, dried foods, other foods that may contain heat-sensitive organisms); 2) products containing obligately aerobic bacteria that are likely to form a significant proportion of the total flora (e.g. Pseudomonas spp.); 3) products that contain small particles that can prove difficult to distinguish from colonies in a pour plate; 4) products whose intense colour prevents the recognition of colonies in a pour plate; 5) products for which distinction between different types of colony is required as part of the assessment of food quality. In addition to the manual spread plating technique, an annex to ISO 4833-2:2013 also specifies the use of a spiral plater, a rapid method of performing surface colony counts. The applicability of ISO 4833-2:2013 to the examination of certain fermented food and animal feeds is limited and other media or incubation conditions can be more appropriate. However, this method can be applied to such products even though it is possible that the predominant microorganisms in these products are not detected effectively. For some matrices, the method described in ISO 4833-2:2013 can give different results to those obtained using the method described in ISO 4833‑1 |

ISO/TR 13136:2012 describes the identification of Shiga toxin-producing Escherichia coli (STEC) by means of the detection of the following genes: a) the major virulence genes of STEC, stx and eae; b) the genes associated with the serogroups O157, O111, O26, O103, and O145.In any case, when one or both of the stx genes is/are detected, the isolation of the strain is attempted.The isolation of STEC from samples positive for the presence of the genes specifying the serogroups in the scope of this method can be facilitated by ingrogroup-specific enrichment techniques (e.g. immunomagnetic separation, IMS).The protocol uses real-time PCR as the reference technology for detection of the virulence and serogroup-associated genes. ISO/TR 13136:2012 is applicable to: 1) products intended for human consumption and the feeding of animals; 2) environmental samples in the area of food production and food handling; 3) environmental samples in the area of primary production |

ISO 9308-2:2012 specifies a method for the enumeration of E. coli and coliform bacteria in water. The method is based on the growth of target organisms in a liquid medium and calculation of the "Most Probable Number" (MPN) of organisms by reference to MPN tables. This method can be applied to all types of water, including those containing an appreciable amount of suspended matter and high background counts of heterotrophic bacteria. However it must not be used for the enumeration of coliform bacteria in marine water. When using for the enumeration of E. coli in marine waters, a 1?10 dilution in sterile water is typically required, although the method has been shown to work well with some marine waters that have a lower than normal concentration of salts. In the absence of data to support the use of the method without dilution, a 1?10 dilution is used. This method relies upon the detection of E. coli based upon expression of the enzyme b-D-glucuronidase and consequently does not detect many of the enterohaemorhagic strains of E. coli, which do not typically express this enzyme. Additionally, there are a small number of other E. coli strains that do not express b-D-glucuronidase. The choice of tests used in the detection and confirmation of the coliform group of bacteria, including E. coli, can be regarded as part of a continuous sequence. The extent of confirmation with a particular sample depends partly on the nature of the water and partly on the reasons for the examination. The test described in ISO 9308-2:2012 provides a confirmed result with no requirement for further confirmation of positive wells |
