Steve J. Crossley, B.Sc.(Hons), M.Sc., CChem MR.SC

Mr. Crossley has over 20 years experience in food safety and chemical risk assessment and has extensive knowledge of Codex, food surveillance, and food regulatory risk analysis. He has been an invited expert to a number of Joint FAO/WHO Meetings and Expert Consultations and has also acted as a consultant to the FAO and WHO.

Prior to joining Exponent, Mr. Crossley managed a wide range of scientific programs during his 9 years at Food Standards Australia New Zealand (FSANZ), based in Canberra, Australia. This included the oversight of dietary exposure assessments, food emergencies and recalls, imported food risk assessments, emerging chemical hazards, maximum residue limits, food composition, consumer surveys, and the monitoring and surveillance of the food supply.

Mr. Crossley acted as the Australian Chief Scientist and on the FSANZ Executive on a number of occasions. He has also represented both the Australian and UK governments at Codex and other international meetings, and has undertaken ‘capacity building’ training of scientists from SE Asian governments in chemical risk assessment.

Mr. Crossley started his career in the UK Civil Service as an analytical chemist at DEFRA’s (formerly MAFF) Central Science Laboratory. He then joined the Pesticide Safety Directorate as a regulatory scientist, undertaking dietary risk assessments for pesticide residues and developing methodology for calculating acute dietary exposure. During his 9 years at PSD, Mr. Crossley also participated in technical negotiations relating to EU maximum residue levels (MR.Ls) and in the FAO expert panel of the FAO/WHO Joint Meeting on Pesticide Residues.
