Complete analysis of contaminants in food 食品污染物的完整分析

The global food chain 全球食品链• A global food chain is difficult to control 全球食品链难以控制• Food safety cultures and standards differ across the world 食品安全文化和标准的全球差异• Modern food production involves use of a large number of

ingredients procured globally 现代食品生产使用大量全球化供应的物料• When things go wrong ‘tracking and tracing’ is difficult 食品安全危机的跟踪和追溯困难

Threats to our food supply 食品供给的威胁• Global market – new food sources with unknown

risks 全球市场——新食品来源的未知危险• More ‘added value’ by food processors in exporting

countries 出口国食品加工者更多的“附加价值”• Economic effects – rising prices/shortages drive

deliberate adulteration 经济影响——价格提升 / 短缺和掺假• Environmental changes 环境改变• Climate change 气候改变

Food safety – target analysis 食品安全目标分析

1. Pathogenic microrganisms致病微生物

2. Pesticides农残

3. Veterinary drugs兽药

4. Mycotoxins真菌毒素

5. Marine biotoxins海洋生物毒素

6. Dioxins, PCBs, & heavy metals 二恶英 , 持久性有机污染物 , 重金属7. Packaging contaminants

包装污染

Mastitis (PathoProof Assays) 牛乳腺炎确证分析• Big losses each year to the dairy industry

due to reduced milk production and discarded milk unfit for human consumption每年造成的减产和丢弃，乳品工业损失巨大

• Economical losses ~US$200/cow/year每年每头经济损失约 200美金

• More than 100 different bacteria are responsible for causing mastitis 超过 100个不同的细菌导致乳腺炎

• Bacterial culturing is still regarded as the gold standard in mastitis diagnostics 细菌培养仍是公认的乳腺炎诊断金标准

• However, there are many problems related to culturing但培养的方法存在很多问题
