FOG (Fats, Oils, & Grease)

FOG

What is 'FOG'?
FOG stands for fats, oils, and grease and is generated by food preparation from food products including:

  • cooking oil, shortening, butter, margarine, and lard
  • meat and foodscraps
  • sauces
  • dairy products
  • baked goods

You will find FOG anywhere that food is prepared, including: residential homes, apartments, restaurants, cafeterias, hospitals, etc. Most FOG results from cooking meats or using oil or grease to cook, but it can also come from products like salad dressing, marinades, sauces, and other fat-containing foods. FOG gets into the sewer system typically via direct discharge or through disposal of food waste and it can lead to build up within the sewer system. Once in the sewer system, FOG can build up on the interior of the pipes causing reduced pipe capacity and an increase in blockages which may result in a sewer overflow. 

Why is FOG harmful?
When FOG gets into the sewer lines, it can cause blockages and backups resulting in damages to homes and businesses. Not only does this create a public health problem, but it can be costly to home and business owers and the municipality. 

What are some ways to keep FOG out of the sewer system?
Every household should follow these simple guidelines to help protect our cities sewer lines:

  • NEVER pour grease down drains or toilets.
  • Do not dispose of FOG or fatty foods through the garbage disposal.
  • Collect cooking grease in cans or other recepticles and dispose of in the trash.
  • Use strainer baskets in the sink to catch food scraps.
  • Dry wipe pots, pans, grills, and dishes before washing.
  • Do not use "degreasers" to clean up -- these tend to just temporarily break down grease.
  • Reduce the use of FOG in cooking and cook fewer fatty foods.
