Appendix N Bulk Milk Tanker Screening Test Flashcards
What is the purpose of the CHARM® SL test?
To test for beta-lactam in raw commingled cow, sheep, water buffalo, and goat milk
This test is specifically designed for detecting antibiotic residues.
What is the incubation temperature and time for the SL beta-lactam test?
56+1°C for 8 minutes
This is the required condition for the SL beta-lactam test.
What is the incubation temperature and time for the SL3 beta-lactam test?
56+1°C for 3 minutes
The SL3 test has a shorter incubation time compared to the SL test.
What is the incubation temperature for the BL30SEC test?
56+1°C
The BL30SEC test is optional for SL and SL3.
What are the general requirements for the tests according to Appendix N?
See Appendix N General Requirements items 1-8 & 15
These items outline the foundational criteria for conducting the tests.
What records must be maintained daily for the incubator?
Temperature records
Daily checks are essential for ensuring the accuracy of the testing process.
What is required for the Charm EZ and EZ Protect in terms of temperature checks?
Printout acceptable for daily temperature check; annual accuracy check required
This ensures compliance and reliability in testing.
What should be done with the incubator lid when not running tests?
Lid closed (slightly sprung so that timer not active)
This prevents unnecessary activation of the timer and maintains the integrity of the equipment.
True or False: All tolerances for the tests are set at $5%.
True
This tolerance level is standard unless otherwise stated.
What is the significance of the Charm Sciences Strip Incubator’s temperature measuring device?
To ensure accurate incubation temperatures are maintained
Each incubator should have its own measuring device.
Fill in the blank: The Charm Sciences Strip Incubator requires a _______ if not included.
Timer
A timer is essential for tracking incubation times accurately.
What must be checked for accuracy before initial use and annually?
All test temperature measuring devices
This includes checking against a NIST traceable thermometer.
How accurate must temperature measuring devices be when checked at temperature(s) of use?
Accurate to $1°C
This ensures reliability in temperature measurements.
What information should be recorded/documented when checking temperature measuring devices?
Identification/location, date of check, temperature(s) checked, and correction factor(s)
Tagging individual devices with this information helps maintain accuracy and traceability.
To what nearest measurement should temperature measuring devices be read?
Nearest graduation/recording interval
Labs may optionally interpolate between graduations.
What must the software of temperature monitoring systems do?
Record temperature readings from each sensor/probe at the same or greater frequency as stipulated for MIG or AIG thermometers
Optionally, it can register an alert/alarm when out of the acceptable temperature range.
What must be documented when temperatures are out of acceptable range for more than two hours?
The event must be documented and corrective action taken as necessary
Records must be maintained for auditing purposes.
What is an optional feature for temperature monitoring systems in case of power failure?
A minimum two-day backup power source (battery/electrical)
This applies to the temperature monitoring system and/or all required sensors/probes.
How often should automatic temperature recording instruments be compared against an accurate thermometer?
Weekly
Maintaining records of these comparisons ensures ongoing accuracy.
What must temperature measuring devices be checked for at another location?
Accuracy
A copy of the record must be on-site.
Are dial thermometers used in the laboratory?
No
Dial thermometers are specifically noted as not being used in the laboratory.
What is the temperature range that refrigeration should maintain for samples?
0.0-4.5°C
This range is critical for preserving the integrity of samples.
What types of items should not be stored in refrigeration units?
Food or drink for consumption
Refrigeration is designated for milk, milk products, media, and reagents only.
How often should temperature records be downloaded from refrigeration units?
Daily
This includes recordings from two temperature measuring devices.
