When the Philadelphia  health department shuts down a restaurant, it's almost certainly for at least one of three reasons.

Two of them, pest infestations and a lack of hot water, can be due to negligence, or not. Mice, roaches and flies can slip into the best of eateries. And even well-maintained hot water heaters can burst without warning.

But every month, the health department orders dozens of restaurants, groceries and food carts to close immediately for something  wholy preventable. They're shuttered because there's no employee there who holds a food safety certificate.  And in the eyes of Health, that's a cardinal sin.

Community College of Philadelphia offers its 15-hour certification course every month. At $225 per employee, it isn't cheap. But weighed against two days of lost business in the wake of a health department shut down, it's a bargain.

The businesses below were inspected between Oct. 7 and Oct. 21. Each inspection is generally regarded as a "snapshot in time," and not necessarily a reflection of day-to-day conditions. Most violations were addressed on site.

Included with each listing is an edited selection of infractions noted by health department sanitarians. Click on the restaurant's name or date of inspection to see a detailed report.

If you suspect you've contracted food poisoning at a Philadelphia eatery or have a sanitation complaint, contact the health department at 215-685-7495.
