小心中“蛋” 美国2亿多鸡蛋受污染被召回

--------------------------------------------------------------------------------

世界日报 2010-08-19 09:56:07

据美国《世界日报》报道,美国大众食品再拉警报,美国的一家大型鸡蛋供应商日前宣布召回2.28亿可能受到沙门氏菌污染的鸡蛋。监督鸡蛋食品安全的组织 eggsafety.org17日公布,知名超市Ralphs 、Albertsons与其它品牌贩卖的鸡蛋,因疑似感染沙门氏菌污染宣布召回。不过,这批鸡蛋并未流到华人超市内,专家建议选购前仍应看清标示,烹调时应将鸡蛋煮沸方可食用。


  召回鸡蛋是从爱荷华输出,目前掌握到的流向有加州、伊利诺伊州、密苏里州、科罗拉多州、内布拉斯加州、明尼苏达州、威斯康星州与爱荷华州本地等。在加州设立多处零售分店的大华超市公关部经理曹其峥表示,旗下超市并未向爱荷华州进口鸡蛋,因此请民众安心选用。另她实际调查后提到,这批鸡蛋多数流向是餐厅与食堂,超市较少向该地进口鸡蛋。

  张国贤医师表示,成人一般感染多半是腹泻症状,大概几天可以痊愈,唯独小孩子感染得特别注意,若发现孩童发烧、腹泻、脱水与呕吐应送医就诊。另一位华人医师包炜说明,沙门氏菌感染并非首例,若干年前某航空公司因马铃薯色拉染沙门氏菌引发轩然大波。

  包炜表示,马铃薯色拉有食用油、鸡蛋,放入冷藏环境中若温度不低,很可能成为沙门氏菌滋生温床。一般厨师烹调时,若本身带有沙门氏菌就会透过食物扩散,所以联邦食品卫生局将沙门氏菌感染列为强制申报疾病(Reportable diseases),一旦发现案例得长期追踪到痊愈,才可放行回归职场。治疗的方法,是用点滴与消炎药治疗。沙门氏菌主要会引起腹泻,这是体内细菌所导致,包炜说发现症状时切勿随意服用坊间止泄药,因为会造成肠胃蠕动减缓,相对地无法将毒素排出,造成更严重的伤害。

Worried about bad eggs? How to buy the healthiest ones
What 'free-range,' 'cage-free,' 'organic' and 'natural' truly mean. Are they really safer? Video Salmonella source still unknown in egg scare .Advertisement | ad info

Share Print Font: +-In the wake of the nationwide recall of eggs for contamination with salmonella, many consumers may be wondering what types of eggs are healthiest and safest to buy?

More than 90 percent of U.S. eggs come from caged hens. These birds have a space smaller than the size of a sheet of paper to move around, and live in filthy conditions. Aside from animal welfare concerns, that's bad for our health, too, Pennsylvania State University shows, because researchers recently found eggs raised on pasture are much more nutritious than eggs from their caged counterparts.

6 things food industry execs aren't telling you

Penn State's study, published recently in the journal Renewable Agriculture and Food Systems found that pastured hens—ones kept outside on different pastures where they can exhibit natural behavior and forage for bugs and grasses—boasted higher vitamin and omega-3 fatty acid levels when compared to their commercially fed, battery-cage-kept counterparts. Eggs from pastured hens contained twice as much vitamin E and 2.5 times more total omega-3 fatty acids as the eggs from caged birds contained.

12 reasons to buy only organic

What it means
There are dozens of claims that manufacturers can make on egg cartons. Some of them are meaningful, but others are just ways to trick consumers into thinking they're buying eggs from happy chickens. (Remember, 90 percent of chicken eggs produced in this country come from the worst type of production system—battery cages.)

..In an ideal situation, you would purchase your eggs from a local farmer in your area who raises chickens on pasture with plenty of space per bird, and uses moveable, open-air chicken houses, sometimes called chicken tractors, to protect the birds from predators. (You can look for this type of farmer on LocalHarvest.org.) Of course, you could also raise backyard chickens, if you have what it takes.

Eliminating cruel chicken cages is a matter of human health as well as animal welfare. The farther you take chickens away from their natural behaviors, the worse the quality of their eggs or meat.

"When you put four or five chickens in tiny cages, they can't engage in normal chicken behavior—pecking in the dirt, dusting. If they're in a cage, they can't do any of these things," explains chicken expert Gail Damerow, author of the classic Storey's Guide to Raising Chickens (Storey, 2010). (She hasn't purchased a store-bought egg since 1982.) "The pressure of the wire cages against their feet causes infections, their feathers rub off on the side of the cages. Basically, they're just totally frustrated. They've got nothing to do. They can't run around and eat flies and take dust baths. They just sit and lay eggs—what kind of life is that?" One result of all that stress and cruelty is that confined birds' eggs contain less nutrition than eggs from hens with room to roam.

Why organic eggs are worth the cost

What the labels on the egg carton really mean:

• "Cage-Free" "Cage-free is certainly not like Old McDonald's farm," explains Paul Shapiro, spokesperson for the Humane Society of the United States. But it's a lot better than battery cages, where most eggs are produced. "Cage-free" means that animals are not kept in cages, but generally they are kept inside in an enclosed building. While this is less than ideal, at least this setup gives animals a chance to spread their wings and lay eggs in nest boxes, which is closer to their natural behavior. Cage-free does not imply antibiotics were not used on hens.

• "Free-Range" or "Free-Roaming" Usually these types of operations allow chickens outside of cages in barns or warehouses, but they aren't required to provide the animals any specific amount of time outside—or even exposure to sunlight indoors. There's no third-party inspection required for free-range claims, and the chickens can be debeaked or forced into molting through starvation, according to the Humane Society of the United States.

..• "Organic" A USDA-certified organic label means the eggs came from hens that were not enclosed in battery cages, and that must be offered access to the outdoors. However, this doesn't guarantee that the animals ever go outside. Organic eggs come from hens that were fed certified-organic feed, free of antibiotics, pesticides, and other animal products. Forced molting and debeaking are permitted in certified-organic production. Annual inspections are required.

• "Natural" This means that the finished product hasn't undergone certain unnatural processes; in this case, that product is the egg. However, just because eggs are labeled natural doesn't mean a hen wasn't pumped up with antibiotics or other unnatural substances. And it certainly doesn't mean the chickens were raised in clean, humane conditions. For all intents and purposes, natural means nothing.

Advertisement | ad info• "Pastured" Pastured chickens should be housed on grassland in portable shelters that are periodically moved to give the chickens fresh pasture, but there's no third-party inspection required to ensure that's what's really happening. Your best bet is to buy eggs from pastured hens at a local farm that raises the hens organically, ensuring they're not exposed to pesticides, animal by-products, or antibiotics.
• "Omega-3-Enriched" This means hens were fed feed with an increased amount of omega-3-rich flaxseeds. However, pasture-raised hens are already higher in beneficial omega-3s, and they get to be outside. Technically, caged hens could also be fed flax feed, so don't equate this label with better living standards.
• "Certified Humane" This means birds are not kept in cages, but they can be kept indoors. They at least have the space to perform natural behaviors. The program of Human Farm Animal Care sets limits on the number of birds that can be contained in the same area, and outside inspectors perform audits. The program does not, however, require that the animals eat organic feed.
• "United Egg Producers Certified" Shapiro says this, along with "natural," is one of the most misleading claims made on an egg carton. While forced molting is prohibited under this certification, debeaking is allowed, along with other cruel and inhumane practices, such as the use of battery cages.

中国再出食品安全问题 南京食小龙虾中毒

--------------------------------------------------------------------------------

中国之声 2010-08-23 06:31:35

  据中国之声《新闻晚高峰》16时52分报道,小龙虾跟一般龙虾不同,价钱较便宜,而且因为体形较细小,可以用不同方式烹调。可是,在南京,餐桌上的美味却成了破坏人们健康的元凶。这几天,南京多家医院陆续收治了十多位因食用小龙虾而入院的病人。这些患者均表现为肌肉酸痛难忍,诊断为肌红蛋白超标导致肌肉溶解,有病情严重的患者甚至还出现了“血尿”的症状,肾脏功能受到严重损伤。

  美味小龙虾怎么吃出了健康大问题?导致发病的元凶到底是不是人们怀疑的洗虾粉? 南京市疾控中心今天就此展开调查。中央台记者杨守华、江苏台记者田柳发来报道。

  8月20号,江苏省人民医院的急诊科来了一对母女,因为食用龙虾出现了肌肉肿胀疼痛的患者,患者宫女士告诉记者,吃完龙虾后,相继出现肌肉胀痛、呼吸困难症状。而家里还有一位朋友,吃的最多,在食用龙虾半小时左右出现相同且更为严重的症状,被紧急送往南京市第一医院抢救。

  在宫女士母女之前,江苏省人民医院已经收治了十多例这样的病人,这引起了医生们的警觉。江苏省人民医院肾内科主任医师刘佳在接受了记者的采访。

  刘佳:就查了肌红蛋白,就发现肌红蛋白非常非常高,正常情况下肌红蛋白不超过50,而这些病人都是上千以上,其中有个病人达到了6000,说明他有比较明显的肌肉溶解。

  类似的病例还出现在南京多家医院。在江苏省省级机关医院,患者周女士在大量食用龙虾后,出现了“血尿”的症状,肾脏功能受到严重损伤。江苏省省级机关医院的医生向记者描述,星期天晚上,周女士突然出现血尿,发现肝、肾功能损坏的比较厉害了。之前曾经询问过周女士,没有中暑、没有服用药物,也没有服用大量酒精,目前唯一导致的因素就是龙虾。

  8月21日,另一名南京市民刘女士也因为食用龙虾后出现了与宫女士相同症状住进了医院,刘女士的肌红蛋白达到了10000,并且已经出现了蛋白尿现象。与其他病例不同,刘女士是买了新鲜龙虾回家自己烹调的。因此可能肯定是龙虾本身出了问题,而不是饭店有问题。

  之前曾有媒体报道,为了让龙虾看上去颜色鲜亮,一些不法小贩用一种名为“洗虾粉”的化学品清洗龙虾。这次多人中毒,人们也怀疑是洗虾粉惹的祸。记者了解到,洗虾粉的成分是草酸,草酸虽然不会破坏人体的肌肉层,但如果草酸摄入量大的话,会影响体内酸碱平衡,出现呕吐、昏迷,严重的可能会导致死亡。因此,清洗龙虾的化学药品嫌疑很大。南京市疾病控制中心主任李解全接受采访时表示,以往龙虾引起的都是一些食物中毒,但主要是因为煮的不到位引起的细菌污染,这次不能轻易下结论是不是细菌引起的,考虑更多的是化学的相关因素。

  今天,南京市疾控中心已经邀请疾控、检验方面的专家,对这几次龙虾中毒的病例进行全面分析、调查。我们也希望疾控部门能够尽快查处中毒的“元凶”,让老百姓能够吃的放心。
