The Department of Health will soon require NYC restaurants to prominently display their cleanliness ratings in windows or entryways, Mayor Bloomberg and State Senator Jeff "Dirty Dozen" Klein announced at a press conference Saturday. The changes which will alter the numbered DOH ratings to a letter-grade system, which has been used for years in LA. The new rules will be implemented over the next two years, and health commissioner Dr. Thomas Frieden says he plans to hire 45 additional restaurant inspectors, adding to the current total of 140. Also, less sanitary restaurants will now be inspected more frequently. Of course, the restaurant industry is cool to the changes; a New York State Restaurant Association rep tells the Times, "a major objection we have is that an inspection is a snapshot, it reflects a condition on a particular day, but not necessarily a long-term condition."
