Microbiology of the food chain - Horizontal method for the enumeration of microorganisms - Part 1: Colony count at 30 °C by the pour plate technique
Also Known As:
ISO 4833-1:2013 is a standard that provides a method for the enumeration of microorganisms in food and feed samples. This method involves the use of a solid medium and aerobic incubation at 30 °C. The standard applies to products intended for human consumption and animal feed, as well as environmental samples in the food and feed production and handling areas.
The purpose of this standard is to provide a reliable count of microorganisms when a low limit of detection is required, such as counts below 10^2/g or 10^2/ml for liquid samples, or below 10^3/g for solid samples. It is also applicable to products that may contain spreading colonies that could obscure the colonies of other organisms, such as certain dairy products likely to contain spreading Bacillus species.
While ISO 4833-1:2013 is generally suitable for the enumeration of microorganisms, it may not be as effective for certain fermented food and animal feed samples. In these cases, alternative media or incubation conditions may be more appropriate. However, the method specified in ISO 4833-1:2013 can still be applied to these products, even though it may not effectively detect the predominant microorganisms.
It is worth noting that the results obtained using ISO 4833-1:2013 may differ from those obtained using the method specified in ISO 4833-2 for some matrices. Therefore, it is important to consider the specific matrix and select the appropriate method accordingly.
