LEAD (PB) CONTAMINATION IN STREET VENDORS FRIED FOODS IN SCHOOL AREA OF PADANG MUNICIPALITY, INDONESIA.

Abstract

This study aimed to analyze the effect of transportation on lead (Pb) concentration in fried street foods of Padang school area and to analyze hygiene and sanitation handling against processed fried street foods ingredients. Samplings for the analysis of Pb concentration in fried street foods of school was conducted at the school area that located on the primary arterial road and the local secondary road in Simpang Haru District. Fried street food sampling and vehicle volume counting were conducted for 7 consecutive school days. In addition, the distribution of questionnaires to students and also to all traders of street food. The average Pb content of fried street food on primary arterial roads in the range of 0.249 – 0.288 ppm and on local secondary roads ranging from 0.155 – 0.218 ppm. The content of Pb in the primary arterial road passes the quality standard set by National Agency of Drug and Food Control Indonesia (0.25 ppm) and SNI (0.2 ppm). While the Pb content of the schools in the local secondary road only passed the SNI quality standard. The levels of Pb in food and volume of vehicles passing through the primary arterial road has a correlation value of 0.714, while on local secondary roads was 0.143. Pb in foods was not only caused by motor vehicle pollutants but also treatment when handling. This can be seen from the number of street vendors who do a positive treatment on hygiene and food sanitation to fried street food only about 30 – 70 %. Introduction:-Data from Indonesian National Social-Economic Survey (2016) mentioned that almost half the people in Indonesia that are equal to 49 % choose fried food. Other preferred snacks in Indonesia are noodles about 45 %. It also occurs in oil as a frying medium. Approximately 290 million tons of oil are consumed each year. The high demand for cooking oil can be a tangible proof of how big it is fried foods consumed by humans by layers of a society of all ages (Ketaren, 2008). Fried street food becomes an option mainly because the price is cheap, tasty, easy to obtain, also can provide energy intake between meals. But in fact, not many know about the safety of these fried street foods to be consumed. One aspect that can cause fried street food is less safe for health if consumed is the contaminant content in it such as microbiological, chemical and physical contamination. The position of selling places on the edge of the highway allows the absorption of heavy metals from motor vehicle fumes, such as lead (Pb) (Lester, 2009). Contamination media can be air, dust, and water (ATSDR, 2010).
