Abstract

In Africa, antibiotic residue investigations in animal food have primarily been focused on meat, neglecting farmed fish. This cross-sectional study conducted in Dar es Salaam, Tanzania, aimed to assess sulphonamide and tetracycline residues in farmed fish, comparing levels with Codex Alimentarius Commission's acceptable daily intake (ADI) and maximum residue limits (MRLs). A total of 84 farmed fish were sampled and analysed in the presence of tetracycline and sulphonamide residues. All samples were positive for sulphonamide residues (100%; n = 84), and 2.4% (n = 2) were positive for tetracycline and consequently also positive for both compounds. Tetracycline levels were below ADI and MRL, 28.5% (n = 24) surpassed the ADI, and 6% (n = 5) of the samples exceeded the MRL for sulphonamide. Regular monitoring of antibiotic residues in aquaculture products is crucial to mitigate health risks and expanding assessments to include other commonly used compounds is warranted.

坦桑尼亚达累斯萨拉姆养殖鱼类中的四环素和磺胺类药物残留及其对人类健康的影响。

在非洲，动物食品中的抗生素残留调查主要集中在肉类，而忽视了养殖鱼类。这项在坦桑尼亚达累斯萨拉姆进行的横断面研究旨在评估养殖鱼类中的磺胺和四环素残留，并将其含量与食品法典委员会规定的每日允许摄入量（ADI）和最大残留限量（MRL）进行比较。共对 84 个养殖鱼类样本进行了四环素和磺胺残留分析。所有样本的磺胺残留均呈阳性（100%；n = 84），2.4%（n = 2）的样本四环素呈阳性，因此这两种化合物也呈阳性。四环素的含量低于每日允许摄入量和最大残留限量，28.5%（n = 24）的样品超过了每日允许摄入量，6%（n = 5）的样品超过了磺胺的最大残留限量。定期监测水产养殖产品中的抗生素残留对降低健康风险至关重要，因此有必要扩大评估范围，将其他常用化合物也包括在内。

期刊介绍： Food Additives & Contaminants: Part B publishes surveillance data indicating the presence and levels of occurrence of designated food additives, residues and contaminants in foods, food supplements and animal feed. Data using validated methods must meet stipulated quality standards to be acceptable and must be presented in a prescribed format for subsequent data-handling. Food Additives & Contaminants: Part B restricts its scope to include certain classes of food additives, residues and contaminants. This is based on a goal of covering those areas where there is a need to record surveillance data for the purposes of exposure and risk assessment. The scope is initially restricted to: Additives - food colours, artificial sweeteners, and preservatives; Residues – veterinary drug and pesticide residues; Contaminants – metals, mycotoxins, phycotoxins, plant toxins, nitrate/nitrite, PCDDs/PCFDs, PCBs, PAHs, acrylamide, 3-MPCD and contaminants derived from food packaging. Readership: The readership includes scientists involved in all aspects of food safety and quality and particularly those involved in monitoring human exposure to chemicals from the diet. Papers reporting surveillance data in areas other than the above should be submitted to Part A . The scope of Part B will be expanded from time-to-time to ensure inclusion of new areas of concern.
