If you're noticing a strong poop smell coming from your kitchen sink, the first thing you should check is your drain. A clogged drain can be caused by a variety of things, such as food particles, grease, and hair. When these substances build up in your drain, they can create a blockage that causes unpleasant odors to linger in your sink.1. Clogged Drain
One of the most common causes of poop smell in the kitchen sink is a sewer gas leak. This can happen when there is a break or crack in your sewer line, allowing the gas to escape and permeate your home. Not only is this smell unpleasant, but it can also be harmful to your health. If you suspect a sewer gas leak, it's important to call a professional plumber immediately.2. Sewer Gas Leak
The vent pipe is an essential part of your plumbing system that allows air to flow through your drains and maintain proper pressure. If your vent pipe becomes blocked, it can cause a buildup of pressure in your pipes, leading to poop smells coming from your kitchen sink. This can be caused by debris, such as leaves or animal nests, obstructing the pipe. A plumber can clear the blockage and restore proper ventilation to your plumbing system.3. Blocked Vent Pipe
Another common cause of poop smell in the kitchen sink is a buildup of grease. When cooking oil and other greasy substances get flushed down the drain, they can solidify and create blockages in your pipes. This not only causes unpleasant odors, but it can also lead to more serious plumbing issues in the future. To prevent this, make sure to properly dispose of grease and oil in the trash instead of pouring it down the sink.4. Grease Buildup
If you've ruled out all other possible causes and the poop smell is still lingering in your kitchen sink, it could be a sign of a broken sewer line. This is a more serious issue that requires immediate attention from a professional plumber. A broken sewer line can lead to sewage backup and other health hazards, so it's important to address it as soon as possible.5. Broken Sewer Line
Mold thrives in warm and damp environments, making your kitchen sink the perfect breeding ground. If you notice a poop smell coming from your sink, it could be a sign of mold growth.

Food debris is a common culprit of poop smells in the kitchen sink. Over time, small particles of food can get stuck in your drain and start to decompose, creating a foul odor. To prevent this, make sure to use a drain stopper to catch any food particles and regularly clean your drain with hot water and vinegar.7. Food Debris in Drain
The P-trap is a curved section of pipe under your sink that is designed to trap water and prevent sewer gases from entering your home. If this trap is not properly installed, it can lead to a poop smell coming from your kitchen sink. A professional plumber can ensure that your P-trap is installed correctly and functioning properly.8. Improperly Installed P-Trap
