Last I checked Kilz had come out with a water-based latex version, haven't had a chance to try it but that might be less noxious...in any case, if the kitchen area can be ventilated well, it shouldn't be a big problem...ALL paints give off potentially toxic fumes, and when painting an enclosed area like Aqua was doing, taking a fresh air break is always a good idea...
