Single service sachets would remove the risk of contamination there is from the scoop/kitchen/mositure getting into the tub,
but
The risk which lead to the advice to make the formula with 70 degree water was due to bacteria geting into the powder during the manufacturing process.
From this document
The presence of Enterobacteriaceae, including E. sakazakii, in packaged PIF is thus not considered to be due to survival of the organism but to recontamination of the product after drying and during the subsequent processing steps (e.g. conveying, tipping and mixing with additional
ingredients) up to the point of filling/packaging.
Recontamination is related to the following three factors, the first two of which are linked:
- The presence of these microorganisms in the processing environment (i.e. external parts of equipment and surroundings of the processing lines), making it possible for them to get into the processing lines.
- The presence of these microorganisms originating from the processing environment (1) on
internal surfaces of equipment that are in direct contact with the product.
- The presence of these microorganisms in ingredients added and mixed into the dry base
powder after the heat-processing step.
Re the Netherlands - well to the extend that it has not adopted the 70 degree guidelines - it is no different to many other European countries.
I do think that the reason the formula companies have not adopted the guidelines are as they see the risk of
- bad PR/legal action as being greater from scalding to person making formula/risk that it is not cooled sufficiently for the baby
- as being greater than the risk to them re infant deaths/serious illness - probably because it is difficult to PROVE the causality?
The main difference for the Netherlands as far as I can see is using water straight from the tap. I wonder if people then heat the formula to serve.
