Baby bottle measurements wrong, potentially harmful
This is sparking calls for Australia and other countries to introduce and enforce industry standards for bottles to prevent formula fed babies from becoming ill.
For the study, Adjunct Associate-Professor Karleen Gribble from the School of Nursing and Midwifery and her colleagues purchased the entire range of infant feeding bottles available for sale in Australia.
After testing, the team found one in five bottles had at least one marking that was deemed so inaccurate that it would fail to meet the requirements of the only existing standard for bottles in the world, the European standard. Markings underestimated and overestimated actual volumes by as much as 43%.
In addition, 2/5 of the bottles were missing at least one marking for a volume that instructions for reconstituting infant formula require parents to measure. In total, 57% had either inaccurate or missing markings.
"Parents using infant formula are routinely instructed to use the volume markers on the bottles to measure water, but this advice assumes that bottle volume markers are accurate," says Associate Professor Gribble
"Unfortunately, our study has shown these markings on many popular products are either incorrect, or missing entirely."
Of the bottles examined, 41% bottles claimed compliance with the European Standard, 6% with non‐existent Australian standards, and 54% bottles had no standard claim.
The bottles claiming compliance with the European standard were just as likely to be inaccurate as those that made no claim, and expensive bottles were no more accurate. ■
