If you've eaten from a food truck or cart in Los Angeles County, chew on this:
About 40% of the roughly 3,200 food trucks and carts cooking up meals in the area have never been inspected in the field by health officials since letter grades were introduced three years ago.
And most of the remaining 60% have been checked out only once a year, even though official guidelines call for at least two annual field inspections.
How do I know that? Because Angelo Bellomo, director of environmental health for the county Department of Public Health, told me so. He oversees inspections of all eateries, including mobile ones.
"This is an area that needs improvement," Bellomo acknowledged.
That's putting it mildly.
Bellomo and I discussed the sorry state of food-truck safety in L.A. after I presented him with what happened to Shimi Cohen.
Cohen, 52, and her husband recently bought hot dogs from a cart at a West L.A. farmers market. "We both ended up with stomach problems," she told me. "It wasn't pleasant."
The couple recovered by the next day, but Cohen was curious. How safe was this cart's food? What was its track record for health inspections?
She contacted the Department of Public Health and made her way through the bureaucratic kudzu to the agency's Vehicle Inspection Program.
Cohen provided the name of the hot dog cart, but that wasn't good enough. No record search could be done without the cart's license plate number.
OK, that's just insane. Who would have a food cart's license plate number, especially a day later?
Cohen's clever husband, it turned out. He was able to find a photo of the license plate online.
So Cohen got back in touch with the Vehicle Inspection Program and learned that there's no record of it ever having been inspected in the field since 2011.
Let's underline that. We're talking about a cart from which hot dogs that have been sitting in warm water for hours are being sold to the public, and it hasn't been given a look-see by field inspectors once in three years.
"I asked why this was," Cohen recalled, "and I was told that they just didn't have enough inspectors."
I contacted the Vehicle Inspection Program and confirmed everything she'd been told. I'm not naming the operator of the hot dog cart because, even though I have no reason to doubt her, I can't verify that Cohen and her husband were sickened by their mobile meal.
What's more important is understanding how health inspectors failed to make at least six field inspections of that hot dog cart over three years, as per county guidelines, and how this is much more common than most people probably realize.
And then there's the enormous difficulty consumers can have trying to access safety info about the 3,200 food trucks and carts classified by the county as "moderate to high risk" because they prepare and serve meals, as opposed to just selling packaged goods.
You can try going to the website of the Department of Public Health and clicking the link for restaurant inspections. This will take you to a page where you can enter the name of the business and then, from a drop-down menu for types of facilities, select "catering truck."
