Great question — answering as the UphillTech team:
Lingering odors are not risky, but they might indicate that raw chicken juices dripped into the oven while it was cool, and, in this case, they could pose a problem. These juices would only be a risk if they came into contact with food or hands. However, once your oven is at cooking temperature, any potential pathogens that might have dripped from the chicken when the oven was cooler, will be mitigated. But, more importantly...has anyone cleaned the oven? That would be my first step. Get some oven cleaner, put on some gloves, follow the directions.
