On-land transport/storage of fresh fishery products (FFP) for up to 3 days in 'tubs' of three-layered poly-ethylene filled with freshwater and ice was compared to the currently authorised practice (fish boxes of high-density poly-ethylene filled with ice). The impact on the survival and growth of biological hazards in fish and the histamine production in fish species associated with a high amount of histidine was assessed. In different modelling scenarios, the FFP are stored on-board in freshwater or seawater/ice (in tubs) and once on-land they are 'handled' (i.e. sorted or gutted and/or filleted) and transferred to either tubs or boxes. The temperature of the FFP was assumed to be the most influential factor affecting relevant hazards. Under reasonably foreseeable 'abusive' scenarios and using a conservative modelling approach, the growth of the relevant hazards (i.e. , spp. and non-proteolytic ), is expected to be < 0.2 log units higher in tubs than in boxes after 3 days when the initial temperature of the fish is 0°C ('keeping' process). Starting at 7°C ('cooling-keeping' process), the expected difference in the growth potential is higher (< 1 log for and < 0.5 log for the other two hazards) due to the poorer cooling capacity of water and ice (tub) compared with ice (box). The survival of relevant hazards is not or is negligibly impacted. Histamine formation due to growth of under the 'keeping' or 'cooling-keeping' process can be up to 0.4 ppm and 1.5 ppm higher, respectively, in tubs as compared to boxes after 3 days, without reaching the legal limit of 100 ppm. The water uptake associated with the storage of the FFP in tubs (which may be up to 6%) does not make a relevant contribution to the differences in microbial growth potential compared to boxes.
将新鲜渔产品（FFP）在装满淡水和冰的三层聚乙烯“桶”中进行长达3天的陆上运输/储存，并与当前授权做法（装满冰的高密度聚乙烯鱼箱）进行比较。评估了对鱼类中生物危害的存活和生长以及与大量组氨酸相关的鱼类品种中组胺产生的影响。在不同的模拟场景中，FFP在船上储存在淡水或海水/冰中（在桶中），一旦上岸，它们会被“处理”（即分拣、去内脏和/或切片），然后转移到桶或箱子中。假设FFP的温度是影响相关危害的最主要因素。在合理可预见的“滥用”场景下，并采用保守的模拟方法，当鱼的初始温度为0°C（“保存”过程）时，3天后桶中相关危害（即 spp.和非蛋白水解 ）的生长预计比箱子中高<0.2 log单位。从7°C开始（“冷却保存”过程），由于水和冰（桶）的冷却能力比冰（箱）差，生长潜力的预期差异更大（ 为<1 log，其他两种危害为<0.5 log）。相关危害的存活没有受到影响或影响可忽略不计。在“保存”或“冷却保存”过程中，由于 的生长导致的组胺形成，3天后桶中的组胺形成分别比箱子中高0.4 ppm和1.5 ppm，且未达到100 ppm的法定限值。与将FFP储存在箱子中相比，FFP储存在桶中时的吸水量（可能高达6%）对微生物生长潜力的差异没有显著影响。
