Can I use pet waste as compost or fertilizer?

NO. Pet waste left on the ground or put in a compost pile can contain harmful organisms. Most compost piles do not get hot enough to kill the bacteria and other organisms in dog and cat waste. The safest method is to pick it up, bag it, and put it in the trash.

What is the problem with pet waste?

Pet waste is a health risk to people, especially children. It is full of bacteria that can make people sick. Some of these organisms can survive in the soil for years. Children who play in the yard and adults who garden are most at risk of infection. Pet waste contains roundworms, E.coli, giardia and many other microorganisms that can be transmitted to people.

If it's washed through storm drains and into a lake, stream or Puget Sound, the bacteria can end up in fish and shellfish. People who eat contaminated shellfish or drink the water can get very sick.
