Abstract

The consumption of private hold poultry foodstuffs, escaping of official maximum residue limit (MRL) controls in the commercial foodstuff, is an important exposure way for the local populations to chlordecone on the French West Indies. Therefore, chlordecone contamination of different tissues in 42 birds from 32 private holders was determined depending on the contamination of the soil of the outside plot but also surveying the rearing practices of these holders of both islands. Chlordecone contents in tissues increased rapidly with this of the topsoil of the site. The most sensitive tissues to chlordecone presence were egg yolk and liver, followed by abdominal fat and finally leg tissue. The rearing practices varied between the surveyed private holders of both islands. Nevertheless, practices for the distribution of feed and water as well as covering of soil were hardly protective, what would increase the exposure risk of these birds to this potentially present soil-bound contaminant. Although depuration of birds seems possible, the ongoing modelization of the necessary time to meet MRL thresholds indicates that such time lapse seems hardly compatible with acceptable delays for private holders. Therefore, very protective rearing practices are the main way to obtain poultry foodstuffs compliant to MRL, what seems possible if the topsoil is contaminated at less than 0.1 mg kg⁻¹ and perhaps up to 0.5 mg kg⁻¹ if protective practices vis-a-vis of soil exposure are very strict. Nevertheless, a higher contamination of the topsoil seems not compatible with compliant poultry foodstuffs.

法属西印度群岛的十氯酮污染地区的家禽污染控制

摘要

食用私有禽类食品，逃避商业食品中官方最高残留限量（MRL）管制，是法属西印度群岛当地居民接触十氯酮的重要途径。因此，确定了来自32个私人饲养场的42只家禽的十氯酮不同组织的污染，这取决于外界小区土壤的污染，还调查了这两个岛屿的这些饲养场的饲养方式。该部位表层土壤中十氯酮含量迅速增加。对十氯酮存在最敏感的组织是蛋黄和肝脏，其次是腹部脂肪，最后是腿组织。在两个岛屿的接受调查的私人拥有者之间，养育方式各不相同。不过，饲料和水分配以及土壤覆盖的实践几乎没有保护性，这会增加这些禽类接触这种潜在存在于土壤中的污染物的风险。尽管净化鸟类似乎是可能的，但为满足MRL阈值所需的时间正在进行的建模表明，这种时间流逝似乎与私人持有者可接受的延误几乎不兼容。因此，非常有保护性的饲养方法是获得符合MRL要求的家禽食品的主要方法，如果表土的污染量小于0.1 mg kg，这似乎是可能的。对满足MRL阈值的必要时间的持续建模表明，这种时间流逝似乎与私人持有人可接受的延迟几乎不兼容。因此，非常有保护性的饲养方法是获得符合MRL要求的家禽食品的主要方法，如果表土的污染量小于0.1 mg kg，这似乎是可能的。对满足MRL阈值的必要时间的持续建模表明，这种时间流逝似乎与私人持有人可接受的延迟几乎不兼容。因此，非常有保护性的饲养方法是获得符合MRL要求的家禽食品的主要方法，如果表土的污染量小于0.1 mg kg，这似乎是可能的。^-1，如果对土壤暴露的防护措施非常严格，则最高可达0.5 mg kg ^-1。然而，表土的较高污染似乎与顺应性家禽食品不相容。
