Abstract

Floor drainage is an integral part in food processing facility which directs surlace wastewater from production environment to sewage system In Malaysia, most small enterprises have some issue in hygiene and drainability aspects, since they were designed and installed by the nonspecialist contractor for food processing. Hence, this project was performed to analyse the occurrence of contamination and flooding due to errors in design and installation of the gully in a burger meat patty producer, Factory Y. It was found that as production time progressed, level of flooding increase with number of clogged holes of Drain Y was observed due to the size of meet remnants with average length ≥ 2 cm that flowed with the wastewater into the grating holes of diameter, Ø =1 cm. In addition, the measured ATP reading was highest for drain edge (10846 RLU/100cm2) followed by perforated holes(5484 RLU/100cm2) and grating surface (3793RLU/100cm2) which do not meet the benchmark for food industry The swab test results showed that the alarming presence of microbes which includes aerobic plate count (APC), Listeria spp. and Escherichia coli. The aerobic plate count is the highest which is 5.3 x 106 CFU/ cm2 in drain edge, followed by 4.5x106 CFU/ cm2 in perforated holes, 2.4x106 CFU/ cm2 in grating surface and 8.1x104 CFU/ cm2in the soil water inside the drain. Lastly, a new design and installation checklist was developed for gully-type floor drain in a meat processing factory (wet production) that can be utilized by small-scale premises when setting up the factory and demonstrated in a new designed model for Factory Y. The current drain at Factory Y has 2 out of 12 criteria for drain 2 at factory Y are met (16.67%) for its design, and 3/1 criteria are met (27.27%) for its installation.It is hope that the insights provided by the study could raise the awareness of the risk caused by inefficient and unhygienic drain on the overall food company's performance
