Food safety and security is around managing risk. It’s around focusing on techniques that address risk components known to add to foodborne illness. Some techniques are more an essential or risky 보다 others. Let’s focus on appropriate cooling of warm food.
You are watching: Which method for cooling should not be used
Improper cooling techniques are a major cause of foodborne illness. In the united States in between 1998 and 2008, not correct cooling practices added to 504 outbreaks linked to restaurants and also delis. Research carried out in 2010 through the Centers for disease Control and also Prevention (CDC) and several state wellness departments including the Minnesota department of Health, reflects the data gathered indicate that countless restaurants are not meeting the encourage cooling processes. A complete of 420 restaurants (50 native Minnesota) participated in the study. Result from this studies indicate that greater focus needs to be inserted on the finest practices the cooling hot food to minimize the danger of foodborne illness.
Temperature peril zone and also 2-stage cooling
Microorganisms prosper well in the temperature danger zone, 140–41 F. Within this range, temperatures between 125 and 70 F allow for the many rapid development of microorganisms. Hence food need to pass with this variety quickly. The 2-stage cooling technique is approved in Minnesota.
Minnesota Food Code says cooked possibly hazardous food or TCS food (foods that need time and temperature manage for safety) shall be cooled:From 140 come 70 F v 2 hours.And native 70 to 41 F or listed below within 4 hours.
Initial 2-hour cool is critical
The initial 2-hour cool is the most an important time period since the food is passing with the temperature range that support the many rapid pathogen growth. If food has actually not got to 70 F within two hours, it must be reheated come 165 F for 15 seconds and then cooled again or thrown away.
Best practices for cooling food
Food needs aid cooling down quickly; that can’t carry out it on its own. Determinants that influence how conveniently foods will cool under include:Size the the food item gift cooled. The thickness of the food or distance to its center plays the biggest part in how quick a food cools.Density of the food. The denser the food, the slower it will certainly cool. For example, chili will take much longer than chicken noodle soup.Container in i m sorry a food is stored. Stainless steel transfers heat from foods quicker than plastic. Initially loosely wrap food items.Size that container. Shallow pans with product depth much less than 2 inches enable the warm from food to disperse quicker than deep pans.
Don"t place warm food in the cooler or freezer
Food walk not relocate through the temperature danger zone fast sufficient if the food is still hot when inserted in the cooler or freezer or kept in bulk. Placing hot food in a cooler might raise the temperature of every little thing being held and may put it in the temperature hazard zone.
Reduce the dimension of food and also divide
Start by reduce the size or massive of food by cutting big food items right into smaller pieces and also dividing big containers right into smaller containers.
Approved techniques to cool food
Approved and efficient methods to cool food include:Ice-water bath and also frequently stirring the food. This promotes faster and an ext even cooling.Ice paddles (plastic container filled with water and frozen) offered to line food in one ice-water bath.Adding ice as an ingredient (if water is one ingredient).Blast or tumble chiller.

Food containers deserve to be loosely extended or uncovered (if protected from overhead contamination) when placed in cooling or cold holding equipment. This facilitates heat transfer native the surface of the food.
Monitor the cooling process
The only method to accurately recognize that time and also temperature needs are being met is by monitoring the process.
Train staff on cooling methods
Staff training needs to include:How and when to examine temps.How come calibrate thermometers.How to keep exact time-temp logs.
