washing the probe with warm water and detergent; sanitising the probe in an appropriate way for your thermometer (alcoholic swabs are often used); rinsing the sanitiser away if necessary (refer to the instructions on the sanitiser); and. allowing the probe to air dry or thoroughly drying it with a disposable towel.
Insert the probe so that the tip is in the centre of the food (or the thickest part). legal requirement that hot food must be kept above 63°C. To check that food in hot holding is above 63°C, use a clean probe. Insert the probe so the tip is in the centre of the food (or the thickest part).
Bring a saucepan of water to a continuous rolling boil on a stove. Insert the thermometer probe and leave it for about 3 minutes. Check and note the temperature. It should read 100°C (unless in an area of high altitude – see 'Calibration in varied altitudes' below).
Clean and sanitise probe thermometers before and after use - use warm soapy water and an alcohol wipe. Place the probe into the thickest part of the food and wait until the temperature stabilises before reading it. Measure packaged chilled food by placing the thermometer length-wise along or between packages.
What is sanitising? Sanitise means to reduce the number of microorganisms on surface to a level that does not permit the transmission of infectious disease. Sanitising involves applying heat and/or sanitising chemicals to a surface.
After Using the Thermometer
Wash, rinse, sanitize with an alcohol prep wipe, and air dry the thermometer after use. Store it in its clean storage case.
So, what is the correct order of cleaning? Generally, it's best to start with decluttering each room, followed by dusting surfaces from top to bottom. Next, clean windows and mirrors, then tackle the floors by vacuuming and mopping. Finish with the kitchen and bathrooms to ensure they're hygienically spotless.
Cleaning vs sanitising
Cleaning is removing general dirt, grease and food waste. Sanitising destroys microorganisms. You need to clean items before you sanitise them.
Wipe the probe with a probe-compatible low-level disinfection (LLD) quaternary ammonium-, hydrogen peroxide-, or bleach-based wipe, or with a soft cloth sprayed with one of those disinfectants.
Thermometer Hygiene: Sanitising thermometers, especially rectal ones, is essential for health. Use warm water, liquid soap and cotton swabs to clean them thoroughly after each use. Ear thermometers can be cleaned with alcohol wipes or rubbing alcohol without damaging their electronic components.
From birth to age 5, the most common way to take a temperature is under the armpit. For children older than 2, temperatures can also be taken by ear or, if the child is able to sit still long enough, by mouth. The most accurate way to take a temperature is in the bum (rectal method).
Push the mercury into an envelope and put the envelope, scotch tape, gloves and the broken thermometer into a sealable plastic bag. Store the mercury in a secure place, preferably away from occupied areas, and contact a licensed hazardous waste vendor for disposal.
The four steps in the cleaning and sanitizing process include cleaning the surface, rinsingthe surface, sanitizing the surface and then. Re-rinsing the surface. Wiping down the surface with a paper towel. Allowing the surface to air dry.
Wash equipment surfaces with a cleaning solution and proper cleaning tool (e.g. nylon pad or cloth towel. Rinse equipment surfaces with clean water. Sanitize equipment surfaces. Allow all surfaces to air dry and then put the unit back together.
The alcohol is usually blended with an aqueous dispersion of carbomers such as Carbopol® to provide the gelling effect, although some products are lower viscosity for use in foam dispensers. The remaining ingredients include moisturizers and fragrance and occasionally coloring may also be added.
Fill a large container with crushed ice, and then add clean cold tap water until container is full. Stir. Place the thermometer stem/probe into the ice water. Make sure the thermometer is not touching bottom or sides of the glass Hold the thermometer by its top for 30 seconds or until the reading stays steady.
Clean and sanitize your thermometer before each use to prevent cross contamination. Verify the accuracy of the thermometer regularly. Calibrate the thermometer at least once every two weeks and whenever it has been dropped, bumped or jarred.
Insert the thermometer stem or probe 2″ into the boiling water, stirring gently for about 10 seconds, then take a reading. A high-quality instant-read thermometer like the ThermoWorks Thermapen ONE should read within +/-0.5°F of the boiling point for your location.
