The number of incidents of food poisoning at food service facilities has decreased since the execution of a hygiene control manual for parge-scale food processing facilities in accordance with the HACCP, however the improvement level for sanitary conditions still cannot be deemed sufficient. Especially nowadays where bacteria capable of causing food poising in small numbers are gaining attention, the thorough cleaning and sterilization of kitchen instruments, hands and fingers is extremely important. Here, in order to comprehend the extent of microbial contamination, we conducted an examination of viable count, Escherichia coli and coliform group on the hands and fingers of food processing personnel and kitchen instruments (cutting boards, dish towels, knives, refrigerator, etc.). Results showed the mean values of 10^1 〜 10^2 /100cm^2 prior to usage and 10^2 〜 10^4 / per hand following usage. As the number of viable bacteria increased, the detection rate for coliform group also increased. The degree of viable count and coliform group contamination was especially high in water bowls for placing rice paddles and tongs during usage, used dish towels, hands and fingers during food preparation, and sponges, with more than half of examination targets having results comparable to the degree of contamination for the floor. With the need for improving sanitary conditions of cutting boards, refrigerator handles, hands and fingers, and sponges for washing, the hygiene instruction using the Lumitester PD-20 was carried out. As a result, the degree of contamination for almost all examination targets improved to Rank A, and in the results for examination of viable bacteria counts conducted simultaneously the values decreased to less than 1/10 〜 1/40 in comparison to those prior to instruction. Since the usage of Lumitester makes quick numerical comprehension of contamination possible, it can be deemed an efficient method for improvement of cleaning and sterilization methods at the workplace. The results of this research show that further minimization of secondary food product contamination risk is possible by introduction of the Lumitester into hygiene control.

Objective : To investigate the limit of validity of assessment of nutritional risk by using serum albumin values, which is handily used for assessing nutrition risk of patients, and explore feasible tools for high risk patients, by comparing index of serum albumin values and other assessment tools : Mini Nutritional Assessment-Short Form (MNA-SF) as a well validated nutrition screening and assessment tool, Barthel Index (BI) as an index of activities of daily living, Karnofsky Performance Scale (KPS) as a tool for assessing patients functional impairment, and Geriatric Nutritional risk Index (GNRI) as based on serum albumin values and the discrepancy between real and ideal weight for the elderly. Subjects : Seventy outpatients at a dialysis institution in Kanagawa prefecture (40 male, 30 female) ; mean age 68.0 ± 10.4 (male 67.9 ± 10.1, female 68.4 ± 11.0). Methods : 1. Examined correlation among outcomes of MNA-SF, BI, KPS, GNRI tools, and also between these outcomes and serum albumin values as an index of Objective Dietary Assessment. 2. Examined outcomes (scores) of MNA-SF methods and GNRI methods with regards to patients of serum albumin values under 3.4 g/dl. Results : (N=70) Correlation between assessment tools; (1) between MNA-SF scores and KPS scores, r=0.4952, p<0.001, (2) between serum albumin values and KPS scores, r=0.3693, p<0.01, (3) between serum albumin values and BI scores, r=0.0819, p=0.5. For patients with albumin values under 3.4 g/dl ; four male : mean albumin value, 3.1± 0.5 g/dl, mean GNRI score, 81.4 ± 6.9 (classified as major risk), five female : mean albumin value, 3.2 ± 0.2 g/dl, mean GNRI score, 89.7 ± 8.2 (classified as moderate risk). Discussion and Conclusion : Based on MNA-SF, which is a well validated nutrition screening and assessment tool, its scores had the higher correlation with KPS scores than the other tool's scores, while weak correlation was found between serum albumin values and KPS scores. It was also found that there was a possibility that BI was not related with serum albumin values. Serum albumin value may be a feasible screening tool of nutritional risk of dialysis outpatients, as it may reflect disease prognosis and severity. However, it alone may not reflect ADL of these patients. Therefore, among these methods, MNA-SF method may have possibility of adequately assessing patients' overall physical condition, while BI method was suggested that it may have possibility for assessing specifically patients' ADL.
