还有一家叫Approved Food的网络食品销售商专门卖past sell-by(best before)date而闻名。据fsa(food standards agency)讲; "best before is an indication of quality rather than safety.Eating food past the best-before date does not necessarily put someone at risk form food poisoning,"
这个真不好理解。。。
好像一个是best before可保质到, 一个是used by可保存到,,,
