The reliability of MOSH/MOAH data: a comment on a recently published article

In this article, we analyse recently published material by Koster et al. (Food Addit Contam Part A, https://doi.org/10.1080/19440049.2019.1678770, 2019) entitled “Mineral Oil Hydrocarbons in Foods: Is the Data Reliable?”. Koster et al. claim to have traced the reasons for laboratory failures to “deliver robust and reliable test results” for the analysis of MOSH/MOAH in some food matrices, however, a careful review revealed that this publication falls short in considering several aspects of assessing the reliability and comparability of analytical data produced by different laboratories.
