This International Standard specifies a method that is applicable for the detection of Trichinella spp. muscle stage larvae in meat of individual animal carcasses intended for human consumption. It is applicable for the examination of meat from domestic and sylvatic animal species which can be infected by nematodes of the genus Trichinella. This method does not allow the determination of the species or genotype of detected parasites; identification can be made by molecular methods.

This document specifies the minimum requirements for quality control of microbiology culture media and diluents in order to demonstrate their ability to detect microorganisms and to ensure reliability of the microbiological test methods described in the ISO Cosmetics Microbiology Standards.
Checking different parameters of media such as growth promotion, absence of microbial growth for non-inoculated media, physical characteristics, and batch contamination can help to assess their quality.
This standard describes mainly growth promotion and microbial control tests and will apply to both commercially ready-to-use media and culture media prepared from dehydrated media or basic constituents in the user’s laboratory.
Other methods may be substituted provided that their equivalence has been demonstrated.

This document establishes the general requirements for the in vitro amplification of nucleic acid sequences (DNA or RNA). It is applicable to the testing for microorganisms and viruses from the food chain using the polymerase chain reaction (PCR).
The minimum requirements laid down in this document are intended to ensure that comparable and reproducible results are obtained in different laboratories.
This document has been established for microorganisms from the food chain and is applicable to:
— products intended for human consumption;
— products for feeding animals;
— environmental samples in the area of food and feed production and handling;
— samples from the primary production stage.
Validation of alternative methods, single laboratory validation, interlaboratory validation for nonproprietary or alternative confirmation methods are not covered by this document. These items in the frame of the microbiology of the food chain are covered by the ISO 16140 series.
