A study of production of radioactive environmental reference materials used for proficiency testing program in Taiwan

To realise radioactive environmental reference materials in Taiwan, seven environmental materials of soil, water, vegetation, meat, airborne particles (filter paper), milk and mushroom samples that are frequently encountered were used to establish the preparation of the reference materials. These seven environmental materials were collected, checked for freedom from radioactivity and prepared according to their properties. The preparation was carried out by using activity about 10–100 times that of the minimum detectable activity (MDA) in routine measurements in the radioactive standard used to spike the inactive material and this standard is traceable to national ionising radioactivity standards (TAF, 2004). To demonstrate sample traceability to the added standard, each sample was carefully measured and its uncertainty evaluated.Based on the recommendations of ISO Guide 35 for evaluation of reference materials and with the above assessment and verification procedures, the uncertainties (k=1) of the spike activity used in making reference materials were: ⁶⁰Co≤4.6%, ¹³⁴Cs≤4.7%, ¹³⁷Cs≤5.0%, total β≤0.6% and ³H≤1.3%.

Variations in total As and As species in rice indicate the need for crop-tracking

Rice is a significant source of arsenic (As) and high consumption is noted for the Brazilian population. Inorganic-As (i-As) accumulation in rice strongly depends on geochemical soil characteristics. These characteristics may be completely different from site to site and it is expected that rice grains grown in different cities would present significant differences concerning total As (t-As) and i-As. In this context, an exploratory study concerning t-As and As species was performed on two Brazilian rice varieties (Puitá and IRGA 424) collected from producers in eight cities in the state of Rio Grande do Sul, Brazil. All samples presented i-As lower than the maximum permissible limit (350 ng g⁻¹) recommended by the FAO/Codex guidelines. Puitá from the city of Arroio Grande presented t-As 2-fold higher than grains grown in Itaqui, 2.6-fold higher than grains from Pelotas, and 1.6-fold lower than grains from Santa Vitória do Palmar. Santa Vitória do Palmar grains presented the highest t-As content (318 ± 11 ng g^-1). Rice grains from four different producers cultivated in the city of Pelotas presented significant variations. Therefore, an extensive rice-traceability is required to improve As mitigation and risk assessment in rice grains.

目的 了解广元市生产销售的桶装水中铜绿假单胞菌的污染状况及污染来源，为保障饮用水安全提供技术支持。 方法 依据GB 8538-2016《饮用天然矿泉水检验方法》对17个批次共85桶桶装水进行铜绿假单胞菌检测，对检出的铜绿假单胞菌进行脉冲场凝胶电泳（PFGE）和多位点序列分析（MLST）。结果 共有7个批次29份样本检出铜绿假单胞菌，不合格率为41.18%（7/17）。PFGE分析了15株菌共得到A-G 7个谱型，相似度为64.2%~100%；MLST分析了27株菌共得到5个ST型别。PFGE和MLST分型结果显示，品牌1、8同属一个型别，与品牌5、6的亲缘关系较近，品牌2、3、7的菌株比较相似，品牌4的菌株则与其他菌株关系较远。 结论 广元地区生产销售的桶装水铜绿假单胞菌污染问题比较严重，不同生产企业之间存在相似度较高的菌株污染，同一品牌不同批次之间存在相同菌株的污染。     

Listeria monocytogenes bacteremia in a centenarian and pathogen traceability: A case report

BACKGROUNDEarly diagnosis and appropriate antibiotic treatment are important to survival of Listeria monocytogenes (L. monocytogenes) bacteremia. Penicillin tends to be the most commonly used antibiotic. However, there are limited data on antibiotic use in elderly patients with serious complications. We describe the clinical presentation, antibiotic therapy, and traceability of L. monocytogenes in a centenarian with a history of eating frozen food.CASE SUMMARYA 102-year-old man suffered from high fever with chill after hematochezia. Tentative diagnoses were lower gastrointestinal hemorrhage and localized peritonitis. Meropenem and ornidazole were the empirical therapy. The patient did not respond and developed multiple system dysfunction even after teicoplanin was added to the therapy. L. monocytogenes was identified from blood cultures on day 5 of admission. The patient had a history of consuming frozen dumplings. Meropenem/ornidazole/teicoplanin were replaced with meropenem/linezolid. The patient gradually became afebrile. He received meropenem/linezolid for 10 d, and piperacillin/tazobactam was applied as step-down treatment for 2 wk with good clinical results. There was no sign of relapse during follow-up after discharge. L. monocytogenes isolates from the patient and frozen dumplings belonged to different serotypes and sequence types (STs): 1/2b and ST5 from the patient and 1/2c and ST9 from the dumplings.CONCLUSIONMore awareness of listeriosis should be raised. Linezolid might be an option for listeriosis in elderly people with serious complications.
