No, The typical dry chem extinguisher has ammonium phosphate, potassium bicarbonate and sodium bicarbonate in it. While the sodium bicarb is nothing more than baking soda the the ammonium bicarb is harmful if swallowed. Potassium bicarb if ingested can upset the electrolyte balance in your body. So in short, don't eat the dry chem contaminated food. Recently the grocery store i was shopping at had a small electrical fire in the poultry section, an employee used a dry chem ext on the fire and they store had to throw out all food that had been in contact with the dust per the health dept. they ended up throwing out 4 1/2 full shopping carts of chicken ( all sealed in plastic) the health dept would not let them rinse and return the sealed packages.

Can an oven be used after extinguishing a fire with a dry powder extinguisher?
It depends on what started the fire and if the electrical equipment was damaged. Chances are if the food burned and didn't burn the oven you should be able to use it after you clean it really well. If the oven itself was on fire I wouldn't use it.

What does the date on fire extinguisher mean?
A fire extinguisher requires routine maintenance and testing to ensure proper function during an emergency. The date, which is often found on a service tag attached to the extinguisher, will either indicate the date of the last test, or the date on which re-certification is required. For most areas in North America, Extinguishers in commercial buildings are to be inspected and re-certified annually, and extinguisher systems in food preparation/commercial kitchen areas semi-annually. In many cases, there is a chart on the flip-side of the service tag, which is to be signed monthly by a responsible person from wherever the extinguisher is installed. This person is often an in-house health and safety representative, who simply checks that the pressure gauge of the extinguisher is in the green or 'charged' zone, and that the extinguisher is accessible and visibly in good condition.
