These include raw seed sprouts, cut melons, cut leafy greens, and cut tomatoes or mixtures of cut tomatoes. Danger zone temperatures facilitate the growth of food-borne bacteria. The term âleafy greensâ includes iceberg lettuce, romaine lettuce, leaf lettuce, butter lettuce, baby leaf lettuce (i.e., immature lettuce or leafy greens), escarole, endive, spring mix, spinach, cabbage, kale, arugula and chard (7). A thin probe thermocouple can be inserted in thicker stem portions of the leaf for a valid reading. Keeping this in view, what is the maximum cold temperature for shredded lettuce? Danger zone in simple terms defines as the specified temperature range in which microorganisms grow rapidly in the food. What temperature should a salad bar be kept at? To verify proper cold holding, measure the product temperature using an appropriate temperature measuring device. Prediction of pathogen growth on iceberg lettuce under real temperature history during distribution from farm to table. Food Sci. Some foods grow bacteria more easily and quickly than other foods. Bacteria can grow fastest during the food temperature danger zone, which is 40°F to 140°F. Take corrective action if temperatures fall within âdanger zone.â Ensure to throw away any cold-holding food that rises above 41 degrees Fahrenheit. Use a microwave, oven, burners, or steamers. According to FDA regulation suggestions, ready-to-eat cold foods (cut fruit and veggies, cheese etc), are not safe to eat if they ever exceed 70 degrees farenheit. To maintain shelf life, cook-chill items have to be cooked at safe temperatures and then chilled within specific ⦠2002. If a hot-holding temperature falls below the 135 degrees Fahrenheit threshold, reheat it to 165 degrees Fahrenheit and place it back in holding. Microbiol. Point out that the temperature range between 41°F and 135°F (5°C and 57°C) is the temperature danger zone. Always reheat to 165 regardless of it's original cooking temperature. If the food is in the temperature danger zone, it should not be accepted. Cut leafy greens must be received at a temperature of 41ºF (5ºC) or less and be free of evidence of previous temperature abuse (3-202.11). This will keep your food out of the temperature danger zone between 4 °C (40 °F) to 60 °C ⦠Pathogenic bacteria can grow rapidly in the âDanger Zone,â the temperature range between 40 and 140 °F, but they do not generally affect the taste, smell, or appearance of a food.

If a food establishment lacks the equipment necessary to maintain the required temperatures of cut leafy greens, the development of procedures for the proper use of time as a public health control may represent a viable alternative to temperature control. Evaluation and Definition of Potentially Hazardous Foods, available at. The product must be marked to indicate the date by which disposal is required, unless the cut product is held less than 24 hours from the time it was cut. This means that the Temperature Danger Zone for food is between 4°C and 60°C / 40°F to 140°F.
