LOUISVILLE, KY (WAVE) - It was one of the most talked about WAVE 3 News investigations in years -- food trucks: clean or dirty?
WAVE 3 News Troubleshooter Eric Flack's hidden camera story last July stirred a fiery response. Now, a new report out this summer is casting the food truck debate in a whole new light.
Food trucks are more popular than ever in Louisville, and changes required by the health department after our initial story aired have made them safer than ever, as well.

At the Gray Street Farmers Market in Louisville, the Sweet 'n' Savory food truck knows to make cleanliness a priority. After all, it's set up in the health department's parking lot.
"Our line gets bigger every time we come here," said co-owner Ashley Giannini.
"We own it. We take pride it in," added her husband and co-owner Ricky Giannini. "If we want it to be successful, we keep it up to standard."

The Louisville Metro Department of Public Health and Wellness heightened its focus on food trucks in October 2013 when it started including them in the same ABC placard ratings system that lets you know how clean brick and mortar restaurants are.
The move came just months after an off-the-cuff comment a few months earlier to WAVE 3 News from health department inspector Connie Mendel enraged the food truck community.
"We feel you can operate safer from an actual building," Mendel said last year. When asked if she would eat from a food truck, Mendel laughed. "No. That's funny."

The story landed us in hot water with food truck fans and owners too. Our undercover video showed one temporary food stand keeping serving utensils in dirty water; and a permanent food truck operator who openly told us: he didn't use the triple sink cleaning system required by law because he thought it was unnecessary.
Food truck operators and fans filled social media arguing those were isolated incidents and that in general, food trucks are safe and sanitary as a normal restaurant.
Now, a new report from The Institute for Justice outside Washington, DC bolsters that argument. Titled Street Eats, Safe Eats, the group studied 34,500 food inspections over a three year period in Louisville and found food trucks outperformed restaurants on cleanliness.

Mobile food vendors averaged around 1.9 health code violations. Restaurants averaged 4.4.
That's no surprise to food truck customer Chris Cook.
"I would bet that food trucks would be under greater scrutiny by the regulatory bodies," Cook said. "So they probably need to keep up their game."
The WAVE 3 News Troubleshooter Department did its own review of food truck inspections over the past year. There were still a few problems Including a couple "C" ratings and one food truck that was temporarily shut down for a lack of running water which continues to be the biggest challenge for some.
But overall the majority of food trucks got glowing health reports. More than two dozen, including Sweet and Savory's crepe truck, had perfect scores.
"We pull the crepe griddles up," said Ashley Giannini, the co-owner of Sweet 'n' Savory. "We clean out underneath them."
The health department is cleaning up its public stance on food trucks as well. It's not just inviting food trucks to set up shop in their front yard but now calling food trucks "a good addition to our city's mix of food opportunities."

That's from a statement the health department gave us, after it declined our request for another on camera interview about food truck cleanliness. Here's the health departments full response:
Food trucks are also likely to get continued positive reviews from fans who trust their food is in good hands.
"As long as they have passed their certifications and everything," said Ruth Wright, eating a crepe from Sweet 'n' Savory, "I'm not worried about it."
