本文件规定了一种检测甲型肝炎病毒（HAV）和诺如病毒基因组I（GI）和II（GII）的方法，该方法来自食品[软水果、叶子、茎和鳞茎蔬菜、瓶装水、双壳贝类（BMS）]或表面的试验样品，使用实时RT-PCR。本方法不适用于检测其他食品（包括多组分食品）或任何其他基质中的目标病毒，也不适用于检测食品、表面或其他基质中的其他病毒。

This document specifies a method for detection of hepatitis A virus (HAV) and norovirus genogroups I (GI) and II (GII), from test samples of foodstuffs [(soft fruit, leaf, stem and bulb vegetables, bottled water, bivalve molluscan shellfish (BMS)] or surfaces using real-time RT-PCR. This method is not validated for detection of the target viruses in other foodstuffs (including multi-component foodstuffs), or any other matrices, nor for the detection of other viruses in foodstuffs, surfaces or other matrices.
