No pesticides are used — and there is no risk of contamination with food poisoning bugs.(沒有使用農藥，也就不存在被污染的蔬菜引起中毒的可能。)

Good hygienic slaughtering practices reduce the contamination of carcasses by faeces, but will not guarantee the absence of Campylobacter from meat and meat products.(良好的衛生屠宰規范可減少糞便對動物尸體造成的污染，但并不會保證在肉類和肉制品中完全沒有彎曲桿菌。)

If coverage against other risks is required, such as breakage, leakage, TPND, hook and contamination damages, the extra premium involved would be for the buyer's account.(如果要加保其它險別，例如破碎險、滲漏險、盜竊遺失險、鉤損和污染險等，額外保險費由買方負擔。)

"You come out and shower with the suit on to get loose contamination off, take off the suit and then shower again to get it off your skin," he said.(“你出來了，穿著這套衣服淋浴，以把松散的沾染物沖洗掉。再脫下服裝，然后再次淋浴，把沾染物從你的皮膚上洗掉”他說。)

Examples range from contamination of the food or water supply, to high levels of air or noise pollution, a chemical accident, a disease outbreak or a natural disaster.(這方面例子的范圍包括從食物或水供應的污染，到空氣或噪音高度污染、化學事故、疾病暴發或自然災害。)

Furthermore, transport of seafood imports over long distances presents opportunities for contamination and decomposition due to improper handling and refrigeration.(此外，進口海鮮長距離的運輸過程會由于處理或者制冷出現錯誤給了微生物污染和分解的機會。)

"Unfortunately, the federal law and the available federal funding don't get at identifying and reducing sources or contamination," said Toni Glymph.(“不幸的是，聯邦法律和可用的聯邦資金并沒有用于識別和減少污染源或污染，”托尼Glymph說。)

Earlier this month, the FDA announced it was restricting entry of all food products from China containing milk after inspectors found the evidence of melamine contamination.(本月早些時候，在檢驗機構發現三聚氰胺污染的證據后，FDA宣布限制從中國進口所有含奶食品。)

The MoD launched Project Cleansweep in 2007 to provide "reassurance" that residual contamination at UK sites did not pose a risk to human health or the environment.(英國國防部于2007年實施了清掃項目，以使公眾確信這些地區的殘留污染不會對公民健康和環境造成威脅。)

In fact, says Chan, while safety rules are strict, more measures are taken to protect the bacteria from contamination than to protect the researchers from the bacteria.(事實上，正如陳汀峰教授所說，盡管有嚴格的安全措施，但將有更多的措施被用以保護細菌免受污染，而非保護研究人員免受細菌的侵犯。)
