Yes, it matters. The first sample is to be taken prior to use of the water and the second sample is
A composite water sample is ONE sample which is made by combining water samples from two or more sources/uses/locations. For example,
Yes it matters. Final rinse water must be taken from the final rinse equipment: this will determine if the rinse equipment
Does documentation need to be obtained proving that the laboratory used for water testing is accredited to ISO 17025 standards?
No. The CanadaGAP manual [in various sections such as 15.1 (Water Assessment)] does not require the operation to obtain a record to
It depends on their water uses and what is being done to the water. If water is used for a final
In Canada, municipal water is assumed to be potable. The glossary definition of “potable water” according to the CanadaGAP Food Safety
In some provinces, the provincial standards for potable water are different from the CanadaGAP requirement of 0 total coliforms and 0 E. coli. Does an operation have to meet the CanadaGAP requirement (which is the same as the microbiological parameters in Health Canada’s Guidelines for Canadian Drinking Water Quality), or do they follow their provincial standards?
In the manual, it would usually depend on which is the stricter requirement and this would need to be followed. However,
What if an accredited lab is not able to report water test results as 0 total coliforms and 0 E. coli? The lab may only be able to report total coliforms as “less than 10” or “less than 1”. What does this mean, and is it acceptable?
When water test results are reported as <10 total coliforms per 100mL of water or <1 total coliforms per 100 mL
If an accredited lab uses a sensitive testing method (i.e., reports an exact number of total coliforms) and the water test results are not 0 total coliforms and 0 E.coli, will an operation autofail an audit?
It depends on what the water is used for. Review the Water (for Fluming and Cleaning) and Ice section within the
If an operation requires potable water/ice do they have to test EACH of their water uses individually?
No. Operations must show that ALL of their water uses are potable. The only way to do this is to take a
