Is there really a difference in CDC scores. 85 is passing. If a ship doesn't pass, they do a quick clean up and retest and pass. Is there really a difference in terms of cleanliness, healthfullness, food preparation on a ship that gets 90, 95, or 100 or are all differences in scores meaningless.
A ship that scores 85 or 90 is by no means "dirty" , but is certainly got a problem or two in cleanliness and food storage temperatures and procedures. That doesn't mean that a dead moose was found in the refrigerator or that anyone found the plague in the butter storage . It might mean that a holding temp was 42 degrees that should have been 38degrees . It might mean that oil was leaking from a compressor. It might also mean the kind of things I won't write here but then they wouldn't be getting an 85 or 90 they would get a 40.
I wouldn't stay off a ship scoring in the high 80's but I'd sure like to now the issues were addressed (and you can be sure on mosr reputable lines that they were). No Ships officer wants to be associated with a poor CDC score. Home office doesn't promote those folks.
