Afood worker has just rinsed a dish after cleaning it what should he do next

 Food worker should let the dish dry (with the help of tissue paper to avoid any growth of germs on wet surface)  after rinsing and also they should sanitize their hand in order to maintain proper hygiene.

Doing so can reduce the level of  surface contamination on dishes (by microbes such as bateria, and viruses).

There should be proper hygiene in preparing and serving food otherwise food may cause illness to people.

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you
