Is it safe to swim in a pool that had duck poop in it?
Probably, as long as the chlorine level was maintained properly during the exposure and proper time was allowed to disinfect the water. A chlorine level on the high side of the ideal range (around 5 ppm) for a day or so would be ideal. Also, any droppings that dry around the pool edge should be cleaned and disinfected as well to prevent the spread of disease/illness.
