INTRODUCTION
There is a potential risk of contamination with
pathogen bacteria during the food processing,
packaging, storage, and transportation but it is
possible to minimize the contamination if sanitary
measures, hygiene practices, proper cooling, careful
handling and proper storage of the products is
enforced. However, there are still cases of outbreaks

The hygiene practice is one of the most important aspects in the production of safe food. The effectiveness of the cleaning and
disinfection programs can be evaluated by continuous examination of the microbiological counts of the surfaces and hands of
the workers by taking swabs.
In a period of 6 months, 717 swabs were examined, 600 of them from working surfaces, and 117 from employees hands, by
using the standard swabbing technique. From the meat production premises 453 swabs were sampled from surfaces and 94
swab samples from workers hands. At the dairy establishments, 147 swabs were taken from the surfaces and 23 swabs from
employees hands. The samples were tested for total bacteria viable count according to ISO 4833:2003 and the enumeration
of Enterobacteriaceae according to ISO 21528-2:2004, and after that the results were evaluated in accordance with Directive
471/2001/EEC. Obtained results from the meat processing plants were the following: 15.6% were unacceptable for total viable
count (TVC) and 7.5% were unacceptable for enumeration of Enterobacteriaceae from the swabs taken from surfaces, and
10.6% and 2.1% respectively from the swabs taken from their workers. The results in the milk processing premises were: 9.5%
unacceptable for TVC and 2% unacceptable for enumeration of Enterobacteriaceae from the swabs from their surfaces, and
17.4% and 8.7% respectively from the swabs taken from their workers.
The results are indicating that although there is a high level of appropriate hygiene practice in all of the food production
premises, there is still a percent of unacceptable results, which suggests a lack of hygiene and can emphasis the need for further
improvement of the cleaning and disinfecting techniques especially for the surfaces in the meat processing premises and an
improvement in the personal hygiene in the dairy industry.

from food-borne bacteria all over the world, which
proves that there is still a lack of hygiene and
subsequently contamination in the whole food chain
(1).
In the food processing establishments, there
are many conditions that would provide a good
environment for the attachment of bacteria and
possible biofilm formation. This encompasses the
flowing water, surfaces at which raw food is handled
and to which bacteria readily attaches, ample
nutrients, raw materials, or an environment which is
bringing the bacteria in the plant and supports their
growth (2, 3).
Attachment of a variety of organisms to food
processing surfaces has been reported by a number
of workers (5, 7, 8) with associated changes in the
