In the context of growing interest in the commercial determinants of health (CDOH) which has been defined as “the systems, practices, and pathways through which commercial actors drive health and equity,” Bennett et al propose that governments implement monitoring of unhealthy commodity industries (UCIs) (including tobacco, alcohol, and ultra-processed foods) as part of their routine public health surveillance. We explore the evidence underpinning that suggestion and provide details on how corporate monitoring might be practically implemented drawing on lessons from tobacco industry monitoring which has been an established part of tobacco control. While governments should actively support such an approach as part of efforts to address commercially driven health harms, we urge caution in governments undertaking monitoring and identify significant barriers to implementation, while also suggesting ways in which those barriers might be overcome.
