近年来,食品安全事故层出不穷,不少学者认为中国食品市场的监管体制不顺、监管法律不完善是食品安全事故多发的主要原因。诚然,这些都是不争的事实。然而,生产者承担的不安全成本过低,导致食品行业普遍缺乏诚信也是问题食品接连不断被生产出来的一个不容忽视的因素。因此,有必要研究抽样误差、检验误差、追溯误差对食品生产者成本的影响,进而不断创新监管工具和监管思路、改进监管技术,让不安全食品的生产者直接承担不安全食品所带来的成本,以此促使生产者为食品安全付出更多努力。  相似文献

目前,突出的食品安全问题与政府管理机制的运行缺陷、内在矛盾有着密切关系。政府在管理职能、管理手段、治理过程、信息传播、法规执行上存在着诸多的问题。因此,厘清矛盾关系,找出监管"失灵"的根源,转变监管理念,调整监管行为,提升监管效能,这样,才能提高政府对食品安全监管的公信力。  相似文献

《刑法》中界定食品的概念应当以《食品安全法》为法律依据,两者在范围上应当保持一致。食品添加剂从食品功能拓展的角度来看,应当属于食品原料。"食品安全"的内涵需要从"无毒无害"、"符合应当有的营养要求"以及"不造成任何形式的危害"三个方面加以认定,缺少其中任何一项的就属于"不符合食品安全标准的食品"。而"有毒有害的食品"的认定应当以"毒害性"作为具体的判断标准,对象是否属于"非食品原料"不能作为否定罪名成立的消极条件。  相似文献

On May 8, 2014, Vermont passed the Vermont Genetically Engineered Food Labeling Act (Act) requiring labels on certain genetically engineered foods. Once the bill takes effect July 1, 2016, all Vermont-retailed foods with more than 0.9% of their total weight in genetically modified ingredients must be labeled with language stating, “may be partially produced with genetic engineering.” As genetically engineered food are considered scientifically equivalent to their traditional counterparts and are not subject to federal labeling by the FDA, the Act presents several legal questions. Several of the legal questions have been raised in a recent lawsuit filed by the Grocery Manufactures Association that claims the Act violates the First Amendment, Supremacy Clause, and Commerce Clause. This paper will discuss why the Second Circuit could strike down the Act as unconstitutional as to each claim.  相似文献

Housing insecurity is a known threat to child health understanding predictors of housing insecurity can help inform policies to protect the health of young children in low-income households. This study sheds light on the relationship between housing insecurity and availability of housing that is affordable to low-income households.

We developed a county-level index of availability of subsidized housing needed to meet the demand of low-income households. Our results estimate that if subsidized units are made available to an additional 5% of the eligible population, the odds of overcrowding decrease by 26% and the odds of families making multiple moves decrease by 31%. Both of these are known predictors of poor child health outcomes. Thus, these results suggest that state and federal investments in expanding the stock of subsidized housing could reduce housing insecurity and thereby also improve the health and well-being of young children, including their families' food security status.  相似文献

This paper examines a central regulatory mechanism that shapes food economies. Food safety regulations in the United States rely on a science‐based transnational regulatory system known as Hazard Analysis and Critical Control Point (HACCP), which bears central features of what Sabel and Zeitlin identified as experimentalist governance: a new form of regulation that is flexible, responsive, and involves stakeholders in iterative and direct democratic deliberation. The core theoretical question the paper examines is what the reliance on science means for the promise of an experimentalist policy regime to enable a new form of democratic politics. Based on a case study of the HACCP system implemented by the US Department of Agriculture's Food Safety and Inspection Service since the late 1990s, HACCP's reliance on food science has acted as an effective divider between producers who were able to take advantage of the system's flexibility and others for whom this was challenging. There is clear evidence that HACCP posed a disproportionate burden on small processors and that some of them were unable to adapt to the requirements of the regulatory system. In so far as the HACCP‐based food safety regulations delineated the kind of producer that thrived in the system and contributed to the demise of another set of producers, the regulatory system shaped market outcomes.  相似文献

近年来,我国发生了多起食品安全事件,这些事件极大地挑战了我国人民对食品安全的信心。从这些事件中,我们深刻地体会到食品安全立法一定要涵盖"从农田到餐桌"的全过程;从这些事件中,我们也更加深刻地体会到监管部门的责任之重大。我国《食品安全法》发布实施一年多了,面对层出不穷的食品安全事件,我们应认真的加以思索。笔者认为有关部门应继续完善和细化现有的食品安全法律法规,强化监管部门执法人员的责任意识,规范企业生产经营管理,提升企业诚信意识,建立科学可行的监管方法,如建立健全食品安全审计制度,建立健全食品安全信用档案等,以加快全社会信用体系的形成与健康发展。  相似文献

2007年的世界“粮食危机”引起了国际社会的广泛关注。印度作为中国的邻国及仅次于中国的世界第二人口大国,其粮食安全保障体系如今面临着巨大的挑战。一旦印度粮食危机爆发,不仅会对正在崛起的印度经济社会发展造成巨大影响,而且会波及周边国家乃至世界。因此,我们应当关注印度粮食安全,并寻找应对之策。  相似文献
