A linkage of personal, food, and environmental hygiene to presence of E. coli in Warmindo Food Stall.

OBJECTIVE: This study aims to identify pathogenic microbes of foods served by Warmindo and to assess the relationship of environmental sanitation, which is facilities and food, also personal hygiene factors to presence of E. coli. METHODS: This study utilizes a cross section design, data sheet is provided consisting questionnaire and observation results. Chromocult Coliform Agar (CCA) is applied to know positive E. coli contamination. RESULTS: Based on the chi-square analysis, relationship between food sanitation and the presence of E. coli (p=0.03), facilities sanitation (p=0.077), and personal hygiene that there is a significant relationship between hygienic behavior and the presence of E. coli (p=0.046). The laboratory test results show 6 (9.1%) from 33 food samples from Warmindo positive contaminated with E. coli. No meaningful differences between re-heating and direct-cooking food. CONCLUSIONS: There is a relationship between food sanitation, facilities sanitation, and hygienic behavior with Escherichia coli contamination in food sold at Warmindo.

Exposure analysis of benzene in workplace control room A and B PT X.

OBJECTIVE: The control room A and B employees are a high risk of benzene exposure, because they work close to the waste pit which is a source of benzene. This study is to analyze the magnitude of the health risk of benzene exposure to all employees. METHODS: The data of this study were obtained from interviews and the results of environmental quality of PT X. Data were analyzed using Environmental Health Risk Analysis (EHRA) method which compared with RfC for non-carcinogenic effects and CSF for carcinogenic effects. RESULTS: The results of individual calculations for the non-carcinogenic and carcinogenic effect of benzene are at a dangerous level in both real time and lifetime exposure. CONCLUSIONS: In the calculation of carcinogenic and non-carcinogenic risk exposure in real time, half the populations are at risk of being affected and in lifetime the entire populations are at risk of being exposed to these effects.

Exposure analysis of lead (Pb) and chromium (Cr) in workplace workshop PT. X.

OBJECTIVE: The workshop (pipe repair place) owned by PT. X is potential for heavy metal exposure which can exceed the quality standards. This study is to identify and analyze the risk of heavy metal exposure from the production process and compare it with the quality standards for the workplace that have been set by the government. METHODS: This research is a quantitative study using the method of environmental health risk analysis (EHRA). RESULT: The concentration of risk agents that could cause adverse health effects of non-carcinogenic due to lead exposure was 15 workers both realtime and lifetime, chromium exposure was 6 workers in realtime and 15 workers for lifetime. While the results of carcinogenic effects due to lead exposure were 1 worker for lifetime and chromium was 15 workers both realtime and lifetime. CONCLUSION: Efforts to control heavy metals can be carried out through technical engineering, administrative control, and personal protective equipment.
