Natamycin in Argentinean Wines

This problem - if such it is - relates to a chemical which is widely used in the dairy industry in tiny quantities as a mould suppressant on cheese. Under EU rules because natamycin is not permitted in wine it is therefore illegal. (It is not legal in winemaking in Argentina either!) A new German system of analysis first spotted it and ever since Argentinean shipments have been delayed trying to get the only laboratory in Argentina with the capability of such analysis to certify that there is no natamycin in the wine... The most likely source of contamination is, it seems, oak chips where small quantities may have been used by a supplier to ensure the chips remain biologically 'clean'. Meanwhile all Argentinean wines destined for the EU are subject to lengthy shipping delays. Hence please understand that our stock levels do not currently accord well with demand...
