BS EN ISO 4833-1:2013+A1:2022 PDF Download

ISO 4833-1:2013+A1:2022 is a standard titled "Microbiology of the Food Chain: Horizontal Method for the Enumeration of Microorganisms - Colony Count at 30 °C by the Pour Plate Technique." This standard specifies a method for determining the number of viable microorganisms in a sample using the pour plate technique. The pour plate technique involves mixing the sample with a solid medium in a petri dish and allowing the microorganisms to grow into colonies.

ISO 4833-1 is applicable to various products intended for human consumption and animal feeding, as well as environmental samples in the food and feed production and handling areas. It is particularly suitable for samples with a minimum of 10 colonies to be counted on a plate.

The standard is relevant to a wide range of stakeholders, including the food industry, cattle feed industry, manufacturers and suppliers of food products, restaurants, food inspectors, regulatory bodies, and testing laboratories. It provides guidance on the procedure for enumeration of microorganisms, including the preparation of test portions, dilutions, inoculation, incubation, and colony counting.

The use of ISO 4833-1 ensures the safety and quality of food products by establishing a code of practice for the enumeration of microorganisms. Compliance with this standard helps to ensure that food is safe for consumption and meets industry standards.
