As Montgomery’s January deadline banning restaurants and other food vendors from serving trans-fatty acids approaches, county Health and Human Services officials said Tuesday that regulating the law could be difficult and more resources could be needed.

The department will be expected to inspect more than 3,600 food service facilities annually, Health Officer Ulder Tillman told the County Council. Health department employees have been using materials from a similar bill passed in New York City to get the word out about the ban. A Web site, hot line and a series of training courses have also been set up, she said.
