As Boston health inspectors prepare to hand out grades to rate food safety practices at restaurants, officials in nearby Newton are getting their first taste of a similar program.
Early results suggest that since the start of the new system, the suburb's restaurants are doing a better job meeting standards designed to prevent food-borne illness, Newton officials said.
"We've been really pleased," said Deborah C. Youngblood, Newton's health and human services commissioner.
Newton inspectors rated each restaurant's food safety practices this year using a point system. Depending on the numerical score, restaurants were placed into one of four categories — superior, excellent, fair, or unacceptable.
The results were shared with restaurateurs, but the initial round of scoring was not made public. It was intended just to familiarize owners with the system, Youngblood said.
Last month, the city began making the ratings public. The scores are posted in prominent locations inside each establishment — and online — on a rolling basis, as inspections are completed. Officials hope that all of Newton's roughly 200 restaurants will be rated by the end of January, Youngblood said.
By the end of October, 61 restaurants had received a public score. Only a handful fell outside the superior or excellent categories, Youngblood said.
More than eight of 10 restaurants that received public ratings achieved higher scores than during the pilot period, suggesting restaurants stepped up their games, officials said. Nearly half the restaurants saw score increases that bumped them up to the next-highest category.
Youngblood said she didn't expect such immediate improvement.
"I had thought they would improve but that it would take a while," she said.
The program, which Newton officials believe was a first in the state, was developed using grant money from the Food and Drug Administration.
Bob Luz, president and chief executive of the Massachusetts Restaurant Association, said he was not sure yet what to make of the program.
"Newton's implementation is so new that it is too early to tell how it will work," Luz wrote in an e-mail. "The results bear watching."
Still, he commended Newton officials on having a "thorough, inclusive process" that incorporated restaurateurs and residents before the city launched the initiative.
Youngblood said restaurateurs had worried the rating process would become onerous and potentially lead to a drop in sales if they received a poor rating.
"But in other communities that have rolled it out, they have not seen a financial hit to restaurants," she said. "If anything, they've seen an uptick in business because there's an increased confidence among consumers."
Youngblood said the new system provides motivation for restaurateurs to follow the rules. She said that in past years, at some locations, inspectors would repeatedly write the same violations. The infractions typically were not serious enough to prompt serious action such as a shutdown, but the lack of cooperation proved concerning.
"There wasn't quite enough incentive for restaurants to make some of the fixes," she said. "Now the stakes are high."
Newton's system differs in some ways from the program Boston is planning and from other cities' rating systems.
Youngblood said Newton officials had wanted, and would still prefer, a letter grade-based system and had considered requiring ratings be posted in restaurant storefronts, rather than on interior walls, both features of Boston's plan. But Newton officials made concessions.
"It seemed like relatively harmless concessions," said Youngblood, who took over the Health and Human Services Department after development of the rating system began. "This is something that's going to be on the walls of their establishment, and we respect their opinion. They've put a lot of work into these businesses."
Newton inspects each establishment at least once a year. Certain types of establishments, such as sushi restaurants, are inspected more frequently because they are considered to have a higher risk for food-borne illness.
Youngblood said once inspectors issue a score, the rating stands until the restaurant's next full inspection. But if inspectors find that violations have been corrected during interim visits, the city issues a certificate that the restaurant can hang next to its score placard to note the fixes.
Youngblood said the city is working to inform consumers about what the ratings mean.
