Mikrobiologie der Lebensmittelkette - Horizontales Verfahren zur Zählung von Mikroorganismen - Teil 1: Koloniezählung bei 30 °C mittels Gussplattenverfahren (ISO 4833-1:2013); Deutsche Fassung EN ISO 4833-1:2013
Overview
This International Standard 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 products intended for human consumption and for animal feed and environmental samples in the area of food production and handling. The application of this part of the standard is recommended for: - products that require a reliable count when a low limit of detection is specified (below 10 2/g or 10 2/ml for liquid samples or below 103/g for solid samples); - products expected to contain spreading colonies that obscure colonies of other organisms: for example milk and milk products likely to contain spreading Bacillus spp. The applicability of this International Standard 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 may be applied to such products even though it is possible that the predominant microorganisms in those products are not detected effectively. The standard is intended for consumer protection and quality assurance. The committee responsible for this standard is NA 057-01-06 AA "Mikrobiologische Lebensmitteluntersuchung einschließlich Schnellverfahren" ("Microbiology of the food chain") at DIN.
