Background: Foodstuff safety hygiene plays a vital role in the health of humans. Therefore, studying foodstuff production and finding suitable methods to control foodstuff contamination is an urgent issue. Objectives: (1) To evaluate various factors of foodstuff contamination in food services and households in Hoan Kiem and Tay Ho districts of Ha Noi. (2) To discover the knowledge, attitude and practices of foodstuff hygiene of the people who process food. Subject and method: A descriptive epidemiology study that included 34 restaurants, 31 kindergartens and 72 households in the 2 districts of Hanoi. Results: The environmental hygiene in foodstuffs service spots and in the families does not fully satisfy the requirements of foodstuffs safety hygiene. Knowledge, attitude and practice of foodstuffs hygiene of the people who process food in Hoan Kiem and Tay Ho districts are not good. Conclusion: It is very necessary to strengthen the knowledge for co-operating practice guidance of basic foodstuffs safety hygiene for people. Food services, kindergartens, etc\u2026 must have training certificate of foodstuff safety hygiene.

Trombiculid “chigger” mites (Acari) are ectoparasites that feed blood on rodents and another animals. A crosssectional survey was conducted in 7 ecosystems of southern Vietnam from 2015 to 2016. Chigger mites were identified with morphological characteristics and assayed by polymerase chain reaction for detection of rickettsiaceae. Overall chigger infestation among rodents was 23.38%. The chigger index among infested rodents was 19.37 and a mean abundance of 4.61. A total of 2,770 chigger mites were identified belonging to 6 species, 3 genera, and 1 family, and pooled into 141 pools (10-20 chiggers per pool). Two pools (1.4%) of the chiggers were positive for Orientia tsutsugamushi. Ricketsia spp. was not detected in any pools of chiggers. Further studies are needed including a larger number and diverse hosts, and environmental factors to assess scrub typhus.
