i wonder how useful is grading system... once a year then got
grading... you think seeing a place got A and B then it is safer
already meh?
Preventing food posioning is more than just keeping places spick
and spank. Its requires constant learning to prevent and minimise
the chances of posioning.
Seriously, I will not be surprised if a A grading stall cause
food posioning. Out of those 4 stalls per year that causes
posioning, how many of them are grading a? or b?
it is a true that C grading shop has higher chance of
causing food posioning then A, but getting an A still does not mean
that stall is safe.
