Q1: What is the meaning of “ready-to-eat food” and “non-ready-to-eat food” mentioned in the National Standards for Food Safety-Pathogenic Bacteria Limits in Prepackaged Foods (GB 29921-2021)?

A1: “Ready-to-eat food” refers to food that is provided to consumers and can be consumed directly without further bacteriostatic treatment, such as potato chips, chocolate, and hawthorn cake. “Non-ready-to-eat food” refers to food that requires additional cooking, such as fresh and frozen livestock and poultry products.

Q2: Does “soybean isolate protein” belong to the category of “ready-to-eat soybean products” under GB 29921-2021?

A2: The ready-to-eat soybean products in GB 29921-2021 include non-fermented soybean products, fermented soybean products, and soybean protein products. Soybean isolate protein is a non-ready-to-eat soybean product, which does not belong to the category of ready-to-eat soybean products in the standard.

Q3: In GB 29921-2021 the expressions “the first method” and “the second method” have been deleted from the provisions on the test methods for staphylococcus aureus, so how do you choose the test method in the actual testing process?

A3: The deletion does not affect the choice of test methods, because inspectors can make the judgment with the reference to the limits of the specific unit. For example, when the limit unit is “colony-forming unit per gram (CFU/g)”, the plate count method should be adopted; when the limit unit is “not detected in 25g” or “0/25g” the qualitative method should be adopted; when the limit unit is “most probable number per gram (MPN/g)”, MPN counting method should be adopted.
