B | 当地的回应来得很快，下午康保县发布情况通报：视频反映情况属实，系收购商为蔬菜运输保鲜，在装运过程中的违法行为，公安部门已对相关人员、车辆依法采取强制措施，案件正在进一步侦办中。“白菜蘸甲醛”，已经严重突破食品安全底线。    A US civilian airliner had a relatively close encounter with what appeared to be some sort of flying pulsing lights in the sky over North Carolina.,Details of the encounter, which took place on August 12, were shared online by prolific blogger Scott C. Waring, who immediately branded it a UFO sighting.,In the eyewitness account featured on Waring’s blog, the anonymous pilot – the only details he provided about himself were his occupation as “an airline pilot with a major airline in the United States” and his past experience as a military pilot – said the encounter occurred as the plane was flying approximately over the city of Wilmington, while en route from St. Thomas in the US Virgin Islands to Dulles Airport in Virginia.,“At roughly 0055 ET I began seeing slow pulses of light in the sky directly in front of us (to our north). The pulses would last usually 8-10 seconds each and had gaps of darkness lasting anywhere from 10 seconds to over a minute,” the eyewitness account states. “They were slowly moving from left to right. The pulses would be gradual (start very dim and grow into a bright light about the brightness of Venus, and then fade away).”,The plane’s captain also noticed the light and he and the pilot engaged in a discussion about what they were looking at. The pilot also started filming and taking pictures at that point, with the video he recorded from the plane’s cockpit being featured in Waring’s blog post.,“We began seeing 2 lights at a time, often at different altitudes, but always moving generally from left to right when the pulse was at its peak. At one point we watched 2 lights flying in ‘formation,’ almost side by side,” the pilot recalled.,“For a brief time we saw 3 objects at one time. At no point did we see a strobe light or navigation lights on the objects,” he added. “The best way to describe what we saw is 2-3 aircraft circling in left hand turns with their landing lights on, which means that they were only clearly visible when the lights were facing towards us.”,While it wasn’t immediately clear what exactly the lights were, the pilot argued that they were not civilian aircraft, since few of those “can fly above 41,000 feet, and the objects were about 10 degrees above the horizon from our perspective.”,“I was not able to tell the distance of the object from our aircraft, but in the 35+ minutes we watched, they never seemed to get any closer even though we covered about 250 nautical miles in that time. For this reason I believe they were in either the upper atmosphere or in space,” the pilot explained.,He also argued that the lights did not look like a Starlink satellite “train,” and that they definitely were not military aircraft or flares.,Waring, however, exhibited little doubt about what the pilot saw, describing the video recorded by the latter as “amazing and rare footage of a real UFO.”,“This is 100 percent undeniable proof that UFOs are following jets and curious about those aboard them,” the blogger declared.。蘸甲醛的目的，主要是为了减少长途运输过程中蔬菜发热腐烂的情况，还可让蔬菜根部外观保持白净，更易吸引消费者选购。然而违规使用甲醛危害巨大，世界卫生组织（WHO）将其列为一类致癌物，即明确其对人类有致癌作用的物质。《中华人民共和国食品安全法》与《中华人民共和国农产品质量安全法》已作出明确规定，严禁甲醛作为食品用加工助剂进行生产、经营和使用。当地收购商为了白菜的卖相、保鲜，居然公然“添加”甲醛，可谓是置消费者的生命健康于不顾了，性质十分恶劣。然而令人担忧的是，视频中博主表示“随机抽查了多台正在装货的大白菜挂车，结果发现每一辆车都在装车前给白菜蘸甲醛溶液”。如果这些信息属实，恐怕就不是个别商贩的临时起意，更像是当地收购环节的惯常操作。当地既然已经查明事件属实，那么下一步就该查清楚范围有多大、持续了多久，多少被甲醛处理过的白菜已经流入市场、最终去了哪里。装车司机透露，大白菜目的地为江苏宿迁；随后博主又称，其已在合肥某农贸市场的在售大白菜中检出甲醛成分。这些信息是否属实、又是否同源，相关各地都需要顺藤摸瓜、地毯式摸排，把这批甲醛白菜彻底“挑出”，真正为消费者负责。值得注意的是，“甲醛白菜”并非第一次出现。早在2012年，另一省份也发生过蔬菜商贩使用甲醛溶液喷洒白菜进行保鲜的情况。随后，关于“甲醛白菜”的新闻乃至传闻便不时出现，“甲醛白菜”是否存在，一直牵动人心。甚至还有一些网络流传的辟谣帖，称“甲醛保鲜成本大，所以很少会有商家选择做这样的赔本买卖”，“在正规途径购买的蔬菜，基本上不用担心这个问题”。然而现实是不是这样，是否真的只是谣言？虽说对于含甲醛蔬菜的具体危害程度，尚有不同说法，比如有专家就称，“对于食用含有甲醛的蔬菜，目前并无确凿证据显示其具有致癌效果”。

C | 但有没有效果是一回事，消费者知不知情是另一回事。无论如何，消费者不该成为“小白鼠”，甲醛既然被明令禁止添加，那么商家就没有任何理由以“保鲜”为名突破这条红线，把消费者暴露于风险之下。由此也就更显出彻查的必要了。只有尽快查清这批“甲醛蔬菜”数量、流向和超标情况，对危害及影响进行清晰评估，并对相关商贩和责任人依法追责，完善今后的监管措施，给公众一个明确的回应，才能真正打消消费者的疑虑，切实维护食品安全。作者：张十味
