Salmonella is a leading cause of bacterial foodborne illness. We report the collaborative investigative efforts of US and Canadian public health officials during the 2013-2014 international outbreak of multiple Salmonella serotype infections linked to sprouted chia seed powder. The investigation included open-ended interviews of ill persons, traceback, product testing, facility inspections, and trace forward. Ninety-four persons infected with outbreak strains from 16 states and four provinces were identified; 21% were hospitalized and none died. Fifty-four (96%) of 56 persons who consumed chia seed powder, reported 13 different brands that traced back to a single Canadian firm, distributed by four US and eight Canadian companies. Laboratory testing yielded outbreak strains from leftover and intact product. Contaminated product was recalled. Although chia seed powder is a novel outbreak vehicle, sprouted seeds are recognized as an important cause of foodborne illness; firms should follow available guidance to reduce the risk of bacterial contamination during sprouting.
沙门氏菌是细菌性食源性疾病的主要病因。我们报告了美国和加拿大公共卫生官员在2013 - 2014年国际多起沙门氏菌血清型感染疫情期间的协作调查工作，这些感染与发芽奇亚籽粉有关。调查包括对患病人员的开放式访谈、溯源、产品检测、设施检查和顺向追踪。确定了来自16个州和4个省的94名感染疫情菌株的人员；21%的人住院治疗，无人死亡。56名食用奇亚籽粉的人员中有54人（96%）报告了13个不同品牌，这些品牌可追溯到一家加拿大公司，由4家美国公司和8家加拿大公司分销。实验室检测从剩余产品和完整产品中检出了疫情菌株。受污染产品被召回。虽然奇亚籽粉是一种新的疫情传播载体，但发芽种子被认为是食源性疾病的一个重要病因；企业应遵循现有指南，以降低发芽过程中细菌污染的风险。
