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. |

Specifies a horizontal method for the detection of Salmonella. It 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;- samples from the primary production stage such as animal faeces, dust, and swabs.With this horizontal method, most of the Salmonella serovars are intended to be detected. For the detection of some specific serovars, additional culture steps may be needed. For Salmonella Typhi and Salmonella Paratyphi, the procedure is described in Annex D.The selective enrichment medium modified semi-solid Rappaport-Vassiliadis (MSRV) agar is intended for the detection of motile Salmonella and is not appropriate for the detection of non-motile Salmonella strains. |

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 |
| Campo de Aplic.:
|
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 |
