Packets in Japanese Food

Just a friendly word of advice,  often in Japanese food like, onori (seaweed), there is a little packet that contains a dry powdery or grainy substance that is often in a gray or white packet that is used to keep the food dry.  This packet is not food and should not be opened or eaten.

When you eat Japanese noodles, the packages often contain a packet of dry seasoning that you open and put on noodles that have been boiled in water and the seasoning creates the noodle broth.

Well, one day, a relative of mine told me that a person, who shall remain nameless, ate a bowl of noodles but commented that the seasoning tasted a little weird. Well, my relative realized that the "person" put one of the packets used to keep food dry on the noodles. So my relative got excited and called poison control and was told it was okay, but that you really are not supposed to eat that stuff!  Just so you know...
