Freeze Thaw Matter FAQ

Q1: Should consumers be concerned about finding white flakes in their bottled water?

A1: No. During the winter months in Canada, some cases of bottled water may freeze during transport and thaw out when placed on display in a retail outlet. From time-to-time during the freeze-thaw process, white flakes can be seen floating in some bottles. To be clear, there is no health risk associated with this process. The visible precipitate is made up of flakes of calcium, a naturally-occurring mineral found in the water. When they solidify, it creates a white, flaky effect, which is not harmful.
Q2: Should consumers drink bottled water that contains visible white flakes?

A2: While there is no harm in doing so, we generally recommend that consumers not drink bottled water containing visible white flakes as such water may be visually unappealing and it is not consistent with our ideal consumer experience of our products.

Q3: How will I know if my bottled water has been frozen and then thawed?

A3: Simply shaking the contents of the bottled water will help to determine if it has been frozen and then thawed. If visible white flakes appear, that will help to confirm that the contents have been frozen and then thawed. While consumption of these flakes is not harmful, it may be visually unappealing.

Q4: What should I do with bottles of water that have been frozen and then thawed?

A4: It is best to return them to the retailer where you purchased them for replacement or refund.
