Snacks served at schools that are contaminated with Escherichia coli germs run the risk of harming students' health. The World Health Organization states that around 70% of diarrheal disease cases are caused by food contaminated with Escherichia coli. Escherichia coli contamination in school snacks can be influenced by a lack of hygiene and sanitation aspects. This investigation aimed to establish a connection between good cleanliness habits and an E. coli infection in the cafeteria food at Nganjuk District's primary schools. This kind of study has an observational design and a cross-sectional study plan. The research sample consisted of 12 canteens selected through purposive sampling. Data collection methods included observation, interviews, and laboratory tests, followed by univariate analysis with descriptive statistics and bivariate analysis with Fisher's exact test. Laboratory test results explained that of the 12 samples, there were 5 (41.7%) foods contaminated with Escherichia coli. The outcomes demonstrated a link between the handler's hygiene (p = 0.015), sanitation of equipment (p = 0.028), serving process (p = 0.010), peddler facilities (p = 0.045), and Escherichia coli contamination. While the quality of food ingredients (p = 0.222) and TPM sanitation (p = 1.000) do not correlate with Escherichia coli contamination, It can be concluded that personal hygiene of the handler, sanitation of tools, serving process, and poor peddling facilities can increase the contamination of hawker food by Escherichia coli bacteria., Snacks served at schools that are contaminated with Escherichia coli germs run the risk of harming students' health.

In the past three years, the Jiwan Health Centre's area has had the highest dengue fever incidence in Madiun Regency. This area still has many water puddles that serve as mosquito breeding grounds. The Jiwan Health Center reported 40 cases and 2 deaths in 2019, 6 cases in 2020, and 16 cases in 2021. This study aimed to identify environmental and social risk factors linked to dengue fever cases in this region. We used an analytical observation method, including a case-control study, and analyzed data with the chi-square test, using probability sampling. A study that looked at just one variable found that air temperature (36.3%), humidity (83.3%), house index (68.8%), container index (41.3%), the lack of mosquito larvae observer cadres (87.5%), fogging activity (55%), and DHF PSN activity (27.5%) were all dangerous. Bivariate test results showed a correlation between the container index (p = 0.000) and fogging activities (p = 0.042) with DHF incidence. There was no significant connection between dengue incidence, air temperature (p = 0.642), humidity (p = 1.000), house index (p = 0.335), jumantic cadre activities (p = 0.737), or PSN DHF activities (p = 0.453). Environmental and social factors, such as positive larvae presence and fogging activities, contribute to the dengue fever incidence in the Jiwan Health Center's area. For the past three years, this area has consistently had the highest dengue fever cases in Madiun Regency, primarily due to persistent mosquito breeding sites., In the past three years, the Jiwan Health Centre's area has had the highest dengue fever incidence in Madiun Regency.
