as replied before by another member, inspections are random and unannounced as well. ideally, every food establishment is to be inspected every 6 months so you can guess about the time frame when a public health inspector will come.
actually, most restaurants do not have infestations, but in fact only pest control problems. a place not showing up on the list does not mean they will in the future. its just a matter if they keep the pests under control before it turns into an infestation.
hot water does not affect the safety of cooked foods; cooking temperature does.
when i was doing my practicum with vancouver coastal health, the food establishments that i had inspected actually have sanitation policies and cooking plans in place. its true that there is no excuse for failing if every employee were to stick to those policies and plans, but people just don't care enough and let things slide.
the funniest thing is when asking owners/cooks/employees about food safety and sanitation questions. they all get the answers right, then i ask if they know the answers, why are shit not being followed and done to prevent sanitation problems/food related problems. they are speechless afterwards.
the following website allows you to access some inspection reports currently done on facilities and you may also find some few history reports as well. great place to check before heading to restaurants.
