A temporary dispensary（临时诊疗所）/dɪ'spens(ə)rɪ/ at the autumn fairground（露天市场）/'feəgraʊnd/ admitted nine people after they drank the same tonic（补剂）/'tɒnɪk/. A tradesman（商贩）/'treɪdzmən/ had promoted it through advertising（广告宣传）/'ædvətaɪzɪŋ/ as a panacea（万能药）/,pænə'si:ə/ for fitness（身体活力）/'fɪtnəs/, energy, and recovery. Its wrapper（包装纸）/'ræpə/ called it a dietary（膳食类的）/'daɪət(ə)rɪ/ foodstuff（食品）/'fuːdstʌf/ that supplied nourishment（营养）/'nʌrɪʃm(ə)nt/ and sustenance（维持体力的营养）/'sʌst(ə)nəns; -tɪn-/, yet the label disclosed neither an alcoholic（含酒精的）/ælkə'hɒlɪk/ base nor any chemical additive（添加剂）/'ædɪtɪv/. In light of（鉴于）/ɪn laɪt əv/ the cluster, pharmacist（药师）/'fɑːməsɪst/ Lena Voss had to identify the contents and trace every sale before more customers became ill.
The product had moved from a bootleg（非法生产的）/'buːtleg/ brewery（酿造厂）/'brʊərɪ/ to a drugstore（药店）/'drʌgstɔː/, a hypermarket（大型超市）/'haɪpəmɑːkɪt/, and two rural clinics. One druggist（药品经销人员）/'drʌgɪst/ had poured it from a flask（大瓶）/flɑːsk/ into small vials（小瓶）/'vaɪəl/; another attached a handwritten tab（小标签）/tæb/ rather than（而不是）/ˈrɑːðə ðæn/ the original warning. Records from each shop were incomplete, creating a bottleneck（瓶颈）/'bɒt(ə)lnek/ in the recall. At this stage（现阶段）/æt ðɪs steɪdʒ/, Lena compared card payments, delivery times, and batch marks in accordance with（按照）/ɪn əˈkɔːdəns wɪð/ the remaining wrappers. The same code appeared at every outlet.
Laboratory tests found not only an industrial cleaner（工业清洁剂）/'kliːnə/ but also insecticide（杀虫剂）/ɪn'sektɪsaɪd/ in the liquid. The formula was poisonous（有毒的）/'pɒɪzənəs/, and a virulent（致病力强的）/'vɪrʊl(ə)nt; 'vɪrjʊ-/ bacterium explained the fever and inflammation（炎症）/ɪnflə'meɪʃ(ə)n/. The bottle also claimed to contain serum（血清制剂）/'sɪərəm/ and an antidote（解毒剂）/'æntɪdəʊt/ for venom（毒液）/'venəm/ from a venomous（有毒的）/'venəməs/ serpent（毒蛇）/'sɜːp(ə)nt/, but neither was present. Lena told the health officer, 女“We can treat the patients, but we cannot call this mixture a medicine with a safe dose.” The authority seized the stock in question（所涉及的）/ɪn ˈkwestʃən/ and authorized issuance（发布）/'ɪʃjuːəns/ of a mandatory recall.
Clinical review showed why a single remedy was dangerous. One patient had an allergy（过敏症）/'ælədʒɪ/, another had anaemia（贫血）/ə'niːmɪə/, and a third was receiving treatment for leukemia（白血病）/luːˈkiːmiə/. A person with hemophilia（血友病）/ˌhiːməˈfɪliə/ developed a hemorrhage（出血）/ˈhemərɪdʒ/ after also taking aspirin（阿司匹林）/'æsp(ə)rɪn/. A febrile child became irritable（烦躁的）/'ɪrɪtəb(ə)l/. The gynaecology（妇科）/ˌɡaɪnɪˈkɒlədʒi/ unit monitored a pregnant patient, while a clinician used a stethoscope（听诊器）/'steθəskəʊp/ to check another patient's cardiac rhythm and hypertension（高血压）/haɪpə'tenʃ(ə)n/. Although most symptoms were mild, the combination was unhealthy（有害健康的）/ʌn'helθɪ/ enough to require observation, and doctors decided to transfuse（输注）/træns'fjuːz; trɑːns-; -nz-/ compatible blood to one patient.
The treatment team rejected another universal formula. It gave the confirmed overdose（用药过量）/'əʊvədəʊs/ patient an appropriate antidote, but did not add a stimulant（兴奋剂）/'stɪmjʊl(ə)nt/ or sedative（镇静剂）/'sedətɪv/ merely to change alertness. Morphine（吗啡）/'mɔːfiːn/ and any other narcotic（麻醉性的）/nɑː'kɒtɪk/ painkiller（止痛药）/'peɪnkɪlə/ required separate assessment. No patient needed anaesthesia（麻醉）/,ænɪs'θiːzɪə/, an anaesthetic（麻醉的）/,ænɪs'θetɪk/ procedure, or medicine to anaesthetize（使局部麻醉）/ə'niːsθətaɪz/ the skin; an ointment（药膏）/'ɒɪntm(ə)nt/ was used only for local irritation. A psychotherapist（心理治疗师）/,saɪko'θɛrəpɪst/ helped frightened patients maintain composure（镇定）/kəm'pəʊʒə/, while remedial（治疗性的）/rɪ'miːdɪəl/ care focused on hydration and monitoring rather than dramatic intervention.
On that basis（据此）/ɒn ðæt ˈbeɪsɪs/, the authority no longer（不再）/nəʊ ˈlɒŋɡə/ accepted the product under the name of（以……的名义）/ˈʌndə ðə neɪm əv/ a health tonic. Investigators mapped every vial. Retailers had no reason to（没有理由做）/nəʊ ˈriːzən tuː/ choose between（在两者之间选择）/tʃuːz bɪˈtwiːn/ protecting buyers and preserving evidence: they did both by surrendering stock and contacting customers. The brewery stopped production, the fairground stall closed, and follow-up tests found no new cases. The observable result was measurable: all batches were recovered and every patient stabilized, so the recall ended without another poisoning.
