| Food Safety . . .The 90% Rule by Christopher Meier, AVP Operations |

| "Stay focused on what causes 90% of the issues in food safety". For years we have focused on Temperature Control, Personal Hygiene and Cross Contamination. According to the US Centers for Disease Control and Prevention, the most common causes of foodborne illness are: Inadequate Cooling and Cold Holding, Preparing Food Too Far Ahead of Service, Inadequate Reheating, Inadequate Hot Holding, Poor Personal Hygiene or Infected Personnel and Contaminated Raw Foods & Ingredients.
Many restaurants orient their food safety systems and training around these 90% issues which is a great start. But upon further review, these areas represent very broad categories and should be drilled down to smaller increments. For example let’s take a look at Inadequate Cooling and Cold Holding. Maximum training and evaluation value is gained by breaking this issue into two parts: 1) Improper Cooling and 2) Improper Cold Holding. Admittedly, both utilize refrigeration, but they represent completely different processes to the operator. Combining them makes it impossible to identify what causes the true problem, where to take action and what training systems are required. In the restaurant industry, we typically see improper cold holding three times as often as improper cooling. |
Now let’s take a look at Personal Hygiene and Infected Personnel. We recommend breaking this category down into three separate areas:
If we drill down on one area: Hand Washing & Glove Usage, we find that there are eight evaluation zones:
And for each evaluation zone there are another 8-10 training areas including:

The 90% rule is very important, and staying focused on Temperature Control, Personal Hygiene and Cross Contamination is still key. But designing a food safety system that drills down to actionable and measurable zones where you can evaluate the system, train employees and measure results is equally important. |
