Abstract:
The study was performed at Sher-e-Bangla Agricultural University (SAU)
Campus during March 2020 to May 2020 to take ideas about food safety issues. It
was accomplished by survey and lab test on microbiological analysis of milk.
Among the 471 respondents, 50 number interviewed were teachers, officers and
staff at different residential building. Respondents were interviewed to determine
their idea about food safety related authority and acts, hand washing, source of
buying egg & raw milk and transportation practices, raw milk storage, their food
hygiene practices and cleaning of kitchen surfaces were investigated. Survey
exposed that only 34% respondents have idea about food safety authority and 66%
have no idea. After completing the survey, laboratory test was started to find out
pathogen present in milk. Different milk samples were collected from dairy farm
of SAU Campus and SAU market and analyzed for total viable bacterial count
(TVBC) and total coliform count (TCC) in milk. TVBC aids to enumerate only
viable microbes and to determine the contamination and unhygienic conditions of
milk handling. On the other hand, TCC support to know the presence of coliform
bacteria in milk. During TVBC count it was noticed that all raw milk samples
were present at the range of standard value but have significant difference
(P<0.05) among them. Pasteurized milk (sample 5 and sample 6) were also remained
between the range of standard value but have no significant difference (P>0.05). The
results of TCC for sample 1, sample 3, sample 4 were more than the standard value
but sample 2 remained between the range of standard value and there was a
significant difference (P<0.05) among the samples. The results of TCC for two
brands of pasteurized milk (sample 5 and sample 6) were nil (absence of coliform
bacteria) also resembled with the standard value. Therefore, these pasteurized
milk can be suggested for human consumption as it remain between the standard
value. Finally it can be concluded that authority should focuses more on publicity
about the safe food and hygiene practices among the people to ensure good health
and proper sanitation that is an important issue of sustainable development goals
(SDGs).
