In late 1995 and early 1996, Sydney vet Dr Bob Steel reported first-hand experience with a cat dying from thiamine deficiency. This deficiency was attributable to the presence of sulfur dioxide in fresh pet food which was fed to the cat over a period of time. The diagnosis was confirmed, as was the presence of sulfur dioxide in significant levels. Since that time, Dr Steel and the AVA have pursued the issue of preservatives (specifically those producing sulfur dioxide) in fresh pet food. An update on that work follows.
1995年末和1996年初，悉尼兽医鲍勃·斯蒂尔博士报告了一只猫因硫胺素缺乏症死亡的第一手经历。这种缺乏症是由于一段时间内给这只猫喂食的新鲜宠物食品中存在二氧化硫所致。诊断得到了证实，二氧化硫的大量存在也得到了证实。从那时起，斯蒂尔博士和澳大利亚兽医协会一直在追踪新鲜宠物食品中防腐剂（特别是那些产生二氧化硫的防腐剂）的问题。以下是该项工作的最新情况。
