How do you check temperatures with a Bimetallic Stemmed Thermometer?

Insert the stem into the food up to the dimple and wait for the temperature reading to remain steady

What is the Flow of Food?

The path food takes through an operation: Purchasing and receiving through storage, preparing, cooking, holding, cooling, reheating, and serving.

What is a Time-Temperature indicator (TTI)?

Time and temperature monitoring device attached to a food shipment to determine if the product's temperature has exceeded the safe limits during shipment or subsequent storage.

How far must a bimetallic stemmed thermometer be inserted into food to give an accurate reading?

Up to the dimple of the thermometer stem

Before and after using a thermometer what should you do?

Washed, rinsed, sanitized, and air-dried.

What is a key drop delivery?

When a food service operation receives food after-hours when they are closed for business. The supplier is given a key to make the delivery.

What is the accuracy range of a Bimetallic Stemmed Thermometer?

Within +/-2*F or +/-1*C

How do you reject an item or shipment?

1. Set the rejected item aside from the items you are accepting 2. Tell the delivery person exactly what is wrong with the item. Use your purchase agreement to support your decision 3. Get a signed adjustment or credit slip from the delivery person before the item is removed 4. Log the incident on the invoice or receiving document. Be specific about the action taken and the item involved.

What is the most common and versatile type of thermometer?

A Bimetallic stemmed thermometer

What is an example of reconditioning an item that would have been rejected?

A shipment of cans with contaminated surfaces may be cleaned and sanitized, but not if the contamination was the result of damage to the cans.

What is an infrared (laser) thermometer?

A thermometer that uses a laser to measure the temperatures of food and equipment surfaces.

What do you do if there is a recall?

Identify the recalled food Remove the item from inventory away from food, utensils, equipment, linens, and single-use items Label the item in a way that will prevent it from being put back Refer to the vendor's notification or recall notice for what to do with the item

How do you check the temperature of received Reduced-Oxygen packaged (ROP) and bulk food?

Insert the thermometer stem or probe between two packages, as shown in the photo at left. If possible, fold the package around the thermometer stem or probe. Be careful not to puncture the package.

How do you check temperatures for food?

Insert the thermometer stem or probe into the thickest part of the food, wait 15 seconds or until the reading is steady then take another reading in a different spot.

How do you check the temperature of received meat, poultry, and fish?

Insert the thermometer stem or probe into the thickest part of the food. The center is usually the thickest part.

How do you check the temperature of received packaged food?

Open the package and insert the thermometer stem or probe into the

What are some receiving considerations?

Schedule deliveries at a time when they can be received correctly Make specific trained staff responsible for receiving Plan ahead for shipments Visually inspect delivery truck for signs of contamination, check for damaged food, and count quantities

What is an approved supplier?

Suppliers that have been inspected, are able to provide an inspection report, and that meet applicable local, state, and federal laws.

A thermometer used to measure the temperature of food must be accurate to what temperature?

+/-2*F or +/-1*C

A food handler has finished trimming raw chicken on a cutting board and needs it to prep vegetables. What must be done to the cutting board?

It must be washed, rinsed and sanitized.

What is a thermocouple/thermistor?

A thermometer that checks food temperature through a sensor on the top of a metal probe

What is a maximum registering thermometer?

A thermometer that indicates the highest temperature reached during its use. (Often used for checking final rinse temperatures of dishwashing machines)

What should an inspection report review?

Receiving and storage Processing Shipping Cleaning and sanitizing Personal hygiene Staff training Recall program HACCP program or other food safety system

What do you do with a thermometer that can't be calibrated?

Replace it.

What device can be used to record time-temperature abuse during the delivery of food

Time-Temperature indicator

Never use glass thermometers with food items unless...

they are enclosed in a shatterproof casing.

What are the steps to calibrate a thermometer using the boiling-point method?

1. Bring clean tap water to a boil in a deep pan. 2. Put the thermometer stem or probe into the boiling water. Make sure the sensing area is submerged. Wait 30 seconds or until the indicator stops moving. Do not let the stem or probe touch the container. 3. Adjust the thermometer so it reads 212*F (100*C). This temp will vary depending on the boiling point for your elevation.

What are the steps to calibrating a thermometer using the ice-point method?

1. Fill a large container with crushed ice. Add tap water until the container is full (stir well) 2. Put the thermometer stem or probe into the ice water. Make sure the sensing area is submerged. Wait 30 seconds or until the indicator stops moving. 3. Adjust the thermometer so it reads 32*F

What are the guidelines of using a infrared (laser) thermometer?

1. Hold the thermometer as close to the food or equipment as you can without touching it. 2. Remove anything between the thermometer and the food, food package, or equipment. Avoid taking readings through metal or glass. 3. Always follow the manufacturer's guidelines.
