Market Access Unhampered access to markets where traceability is mandatory. Brand Protection Minimise reputation and revenue losses arising from counterfeiting and fraudulent use of brand name. Product recall Reduce costs, increase precision and efficiency while demonstrating control. Addresses consumer confidence, perception and negative publicity. Liability Less vulnerable to liability due to ability to prove that it is not the source of a bio- security or public health problem. Bio-security Speed and accuracy leads to avoidance or limitation of sales ban and mandatory destruction of assets. Value-added Products Origin information promotes high quality and certified products Build product differentiation through verification of credence attributes Expand sales of high value or premium products to niche markets Issue 2: Understanding Industry Needs

How do we integrate? Traceability system Industry systems IT Science

Trace Element Profiling ICP-MS is capable of parts per quadrillion detection limits This is equivalent to being able to find an item of 1cm 2 in 10,000,000 football fields!!!

Typical Trace Element Profile

Forward stepwise LDA analyte selection: Ba, Si, Sr, Mg, Cs, Se, Nb, Th, Ni, Co, Na Australian Regions – Cabernet

Forward stepwise LDA analyte selection: Si, Sr, Ba, Ga, Se, Be, Ni, Ta, Li, Pb, Mn, Ti, Mo, Nb Australian Regions – Chardonnay

Case Study 6 “suspect” samples and 6 “authentic” samples “Authentic” samples are South Australian merlot Are the “suspect” and “authentic” samples the same? If not, can we validate the labelling claim of the “suspect” sample? i.e. Is it South Australian? Is it even Australian?

Is it Australian? Forward stepwise LDA analyte selection: Ba, Sr, Mn, Rb, Na, Si, Mg, Be, Cr, Al, V, Cs, Li, Fe, K, P, Ni, As, Zn, Ca

South Australian Merlot? Forward stepwise LDA analyte selection: Sr, Ni, Si, Li, K
