Food Service Establishments: Fats, Oils & Grease (FOG)
What is FOG? 

FOG refers to fats, oils, and grease entering the sewer system when poured down the drains in restaurants, homes, apartments, industry and public facilities. 

FOG is often disposed of improperly during food preparation and cleanup. When poured down the drain, FOG can build up, blocking sanitary sewer lines. 

Resources for Food Service Establishments

 As a byproduct of cooking, FOG is usually found in:

  • Butter, lard, shortening
  • Cooking oil
  • Meat scraps and grease
  • Baking goods
  • Sauces
  • Sour Cream
  • Gravy
  • Mayonnaise
  • Salad Dressings
  • Food Scraps 
How does proper FOG disposal help my facility?

Save Money

Blockages and overflows in your facility can be expensive to unclog and cleanup.

Keep Your Facility Clean

Sewer backups into your facility can result in unsanitary conditions and health code violations.

Be A Good Neighbor
In severe cases, blockages can lead to sewer overflows to nearby homes, businesses and local streams.
