We surveyed the sanitary conditions for 17 cold and frozen food storage warehouses in Korea,using the following 5 inspections items: “putting into warehouse (A)”, “prevention of cross-contamination (B)”, “storage management (C)”, “temperature control (D)”, and “management of records and documents (E)”, We included 20detailed items. The results of distribution for frequency by five major inspection items showed that “(E)” was the highest,the next “(D)”, “(C)”; and “(B)” was the lowest. In the correlation of inspection scores between total scores, “(B)”and “(C)” were highly related to the total score, therefore, the higher score of “(B)” or “(C)”, the higher for the total score. In details of inspection items, “the management of cross-contamination upon taking product out of the warehouse”had the lowest score with a mean, of 2.67 ± 1.80, and also ranked as first of the 20 items.

Microbial distribution as well as content of salt and preservatives in side dishes was investigated by analyzing cell count of viable cells, coliform bacteria and food poisoning bacteria of sliced squid bokum and anchovy bokum, purchased at 17 dift'erent department stores and 2 different traditional markets in Seoul, which are most preferred by many consumers to any other side dishes available in the market. 6.2 × 10³-1.2 × 10^5 cells/g of viable cells was detected in 19 different samples of the sliced squid bokum, among which samples collected at the traditional markets counted the highest number of viable cells. 16 samples of the sliced squid bokum and 14 samples of the anchovy bokum contained 10³-10^8 cells/g of coliform group. However food poisoning bacteria were not detected in all the samples tested. Salt content was 2.42-4.89 %w/w and 2.28-6.46 %w/w for the sliced squid bokum and the anchovy bokum respectively. Analysis of preservatives by HPLC such as sorbic acid, benzoic acid, dehydroacetic acid and another 6 kinds of esters resulted that 1.0× 73.8 mg/100 g of sorbic acid was detected in the 19 samples of the sliced squid bokum, while only 6 samples of the 15 anchovy bokum samples contained sorbic acid.

목장에서 가축음용수 빛 세척수로 사용하는 목장용수에 대한 위생화학척 상태률 계절척으로 조사하기 위하여 강훤도 및 충청도에 소재한 유우목장 58 곳에서 채취한 목장용수에 대하여 pH, 총경도, 과망간산칼륨소비량, 질산성 질소, 암모니아성 질소, 염소이온, 황산이온, 불소, 철, 납, 카드융, 아연, 망간, 동 및 크롬올 봄과 여름 2 회 조사하였다. 충남지역과 강원지역 목장용수의 pH 는각각 6.49:t 0.09, 6.70 :t 0.06 이었으며， 총경도 9O.2l:t 7.07, 64.53:t 6.38 mg/l, KMn04 소비량 4.13:t 0.62, 4.34 :t 0.26 mg/l , 질산성질소 6.51:t 0.55, 3.6l:t 0.58 mg/l , 염소이온 20.51 :t 1.99, 5.41 :t 1.36 mg/l 그리고 황산이온 6.61 :t 1.02, 7.28:t 1.30 m g/l이었으며, 암모니아성 질소는 거의 검출되지 않았다. 검사한 중금속 불소, 철, 납, 카드륨, 아연, 망간, 동 및 크롬은 검출되지 않았거나 극미량만 검출되었다. 검사항목간의 관계를 비교하면 총갱도, 철산성질소, 염소이용 및 황산이 옹은 검사항목간 상관관계를 나타내었다. 검사항목 중 충남과 강훤 목장용수간 지역켜 차이률 나타낸 항목은 총갱도, 질산성질소 및 염소이온이였으며, 봄과 여름에 차이를 나타낸 항목은 질산성질소 뿐이었다.
