The steps of the mothod were presumptive test for coliforms, fecal coliforms and E. coli, confirmes test for coliforms, fecal coli and E. coli and then completed test for E. coli. An analysis for contamination by E. coli in meals, utensils, and on the hands of the server was also undertaken. The data analyzed in percentage and rank all type of foods and drinks, also rank based on the location.Results: Almost all type of meals was contaminated. Meals with chili sauce were the most risky from the contamination of E. coli (90.15 %), then followed by dry meals (38.89%), while the wet meals were the the most unrisky meals. In  drinks, the highest was lacy juice, followed by jambu (guava) juice, then Sirsak and Orange juices on the third rank, while the mango juice was the lowest contamination. Melon juice, cappucino and fruit-coctail did not have E. coli  contamination.Conclusion: The contamination in the top three rank of contamination could be from the utensils used and foodhandler.

Abstract

Menteri Kesehatan menetapkan bahwa makanan dan minuman tidak boleh mengandung bakteri Escherichia coli (E. coli). Namun, kebanyakan pemerintah daerah tidak menindaklanjutinya dengan menerapkan peraturan yang lebih teknis untuk mencegah penyakit-penyakit yang ditularkan lewat makanan. Penelitian ini bertujuan untuk mengukur kontaminasi E. coli dalam makanan yang dijual oleh pedagang kaki lima (PKL). Seratus PKL di sepanjang Jalan Margonda Kota Depok, Jawa Barat, dipilih secara acak sebagai sampel. Sebanyak 100 PKL, E. coli pada sampel berbagai jenis makanan diukur dengan metode most probable number, sementara sanitasi PKL dan kehigienisan penjamah makanan diamati. Ditemukan secara umum bahwa air bersih yang digunakan untuk memasak, minum, dan mencuci peralatan makan, sarana pembuangan air limbah, peralatan makanan, dan makanan yang disajikan secara tertutup serta perilaku penyaji makanan tidak berhubungan dengan tingkat kontaminasi E. coli (p > 0,05). Sebaliknya, kebanyakan makanan yang disajikan tanpa tutup mengandung E. coli sangat tinggi, meskipun sarana sanitasi dan perilaku hidup bersih dan sehat penjamah makanan sudah cukup baik, kecuali sarana tempat sampah. Ministry of Health regulates that all foods and beverages should not contain Escherichia coli. However, most local government does not implement this requirement by applying more technical local regulation to prevent food borne diseases. The objective of the present study was to quantify E. coli contamination in foods served by street vendors along the Jalan Margonda, City of Depok, West Java. A total of 100 street vendors were selected randomly, from which different types of foods were sampled for E. coli measurement using MPN method. Meanwhile, environmental sanitation of street vendors and personal hygiene of food handlers were observed. It was found that generally clean water for preparing foods and beverages and washing kitchen utensils, sewage system, table utensils, and covered foods as well as serving behavior were not statistically correlated with E. coli contamination (p > 0,05). On the contrary, most the uncovered foods were highly contaminated by E. coli, although sanitation facilities and personal hygiene were adequately good except solid waste disposal.
