食肉的风险
The risks of meat consumption
Imagine having to eat just 40 grams of meat per day.
想象一下，一个人每天只能吃40克的肉制品。
That's roughly the size of a regular burger.
这差不多是一个普通汉堡的份量。
A group of researchers say that's what people should aim for in order to reduce pressure on meat production.
一组研究者认为，每个人都应将此作为一个目标，以减轻肉类食品生产的压力。
Researchers say more and more meat products now have bugs that are resistant to available antibiotics – and that can easily be transmitted to people.
研究者还指出，越来越多肉制品中的细菌已经对现有的抗菌素产生了抗体，这些细菌很容易传染给人类。
So, they want the amounts of the drugs used in livestock regulated.
因此他们希望家畜类养殖中的抗菌素用药量受到管制。
A lot of these antibiotics can be done away with, especially their usage for prevention of disease - that's prophylaxis - and growth promotion, by simply ensuring that the farmer is able to observe… what we call phytosanitary conditions.
“很多抗菌素其实都可以不使用，尤其是当它们用于预防疾病……和促进生长时，只要养殖场主能观察出被我们称之为‘控制植物病害的情况’。”
John usually doesn't allow visitors into the farm.
约翰通常情况下不允许访客进入农场。
He also rears chicken of the same age at a time.
他还会同时饲养处于同一生长期的鸡。
“These sheds also harbour some kind of germs or bacteria. So when the other flock comes out we wash the whole place, we disinfect, and then we have a resting period of about 14 days. “
“这些养殖棚中也藏着一些细菌或病毒。所以当一批动物从棚里出来后，我们会将整个养殖棚都清洗一遍，然后消毒，接着再晾14天左右。”
That way he’s able to prevent diseases and therefore avoid using antibiotics.
这样做他就能预防疾病，并且避免使用抗菌素。
But the vast majority of small-scale farmers in developing countries, and larger scale ones in developed countries, tend to overuse the drugs.
但发展中国家的绝大多数小养殖场，以及发达国家的大型养殖场却往往滥用药物。
If that doesn’t change, the available medicine could be rendered ineffective for treatment in the coming years.
如果这种情况没有得到改善，目前仍有效的药物在未来可能会逐渐失效。
