摘要

Consumption of nut kernels has shown an upward trend due to people's increasing tendency to eat healthy snacks. The purpose of this survey was to establish the microbiological safety of retail edible nut kernel samples of different varieties. Overall Salmonella spp. and Escherichia coli were detected from 0.1% and 0.8% of 2886 edible nut kernels, respectively. S. Senftenberg and S. Tennessee were detected from two pre-packed samples of Brazil nuts (0.4%) and S. Anatum from a pre-packed mixed nuts sample (0.9%; mix: almonds, Brazils, cashews, peanuts, walnuts) indicating a risk to health. The levels of Salmonella ranged from <0.01 to 0.23/g. E. coli at unsatisfactory levels (150/g) was present in another pre-packed Brazils nuts sample (0.2%). E. coli was additionally found at lower levels (range: 3.6-43/g) in Brazils (1.9%), macadamia (1.5%), pistachios (1.1%), walnuts (0.7%), peanuts (0.7%), hazels (0.5%), cashews (0.4%), and almonds (0.3%). Levels of E. coli did not correlate with the presence of Salmonella. The batches contaminated with Salmonella were recalled and Food Standards Agency food alerts were issued to advise against the consumption of the affected products. The presence of Salmonella is unacceptable in ready-to-eat foods and follows that the need for applying good agricultural and hygiene practices and effective decontamination procedures during the production of edible kernels cannot be overemphasized.

Anatum（0.9％；混合：杏仁，巴西，腰果，花生，核桃）表明存在健康风险。沙门氏菌的含量范围从<0.01至0.23 / g。在另一个预先包装的巴西坚果样品中（0.2％），大肠杆菌水平（150 / g）不令人满意。在巴西（1.9％），澳洲坚果（1.5％），开心果（1.1％），核桃（0.7％），花生（0.7％），淡褐色中还发现了较低水平的大肠杆菌（范围：3.6-43 / g） （0.5％），腰果（0.4％）和杏仁（0.3％）。大肠杆菌水平与沙门氏菌的存在无关。召回了受沙门氏菌污染的批次，并发布了食品标准局食品警报以建议不要食用受影响的产品。即食食品中沙门氏菌的存在是不可接受的，因此不能过分强调在食用果仁生产过程中采用良好的农业和卫生习惯以及有效的去污程序的必要性。
