Contamination with Dieffenbachia toxin?

Not sure if this is the place for this

Last night I trimmed some leaves off my Dieffenbachia plant with kitchen shears (not a plant person, can you tell?). I washed them off in my sink with dish soap and washed them in the dishwasher with my other dishes. Now I'm worried that I contaminated all of my dishes with the toxin. Is this a legitimate concern or is it my anxiety? Would this degree of contamination pose a risk for humans/pets?
