“…However, as far as ATP measurements are concerned this would be less problematic as, if cell rupture did occur, the ATP released would presumably be detected from the lysed cells. The degree to which particulate matter will adhere to a surface will depend on the hydrophobicity of the surface, with greater hydrophobicity resulting in greater adhesion (Bower et al, 1996). Some quite marked differences in efficiencies of removal have been recorded even between spores of different species of the same genus (Probst et al, 2011) which must partly reflect differences in spore hydrophilicity.…”

“…Biofilms are ordered structures in which micro-organisms are distributed in a polysaccharide matrix. This will affect the ease with which such micro-organisms may be physically removed from the surface (Bower et al, 1996). Following surface sampling the recovered material must then be released from the swab in order that the required analysis may be carried out.…”

Bioluminescence-based ATP testing of solid surfaces has become well established in the food processing industry as part of general hazard analysis and critical control points (HACCP) measures. The rise in healthcare associated infections (HAIs) at the turn of the century focussed attention on the environment as a potential reservoir of the agents responsible for such infections. In response to the need for objective methods of assessing the efficiency of cleaning in healthcare establishments and for rapid methods for detecting the presence of the pathogens responsible for HAIs, it was proposed that ATP testing of environmental surfaces be introduced. We examine the basis behind the assumptions inherent in these proposals. Intracellular ATP levels are shown to vary between microbial taxa and according to environmental conditions. Good correlations between microbial numbers and ATP levels have been obtained under certain specific conditions, but never within healthcare settings. Notwithstanding, ATP testing may still have a role in providing reassurance that cleaning regimes are being carried out satisfactorily. However, ATP results should not be interpreted as surrogate indicators for the presence of microbial pathogens.

“…However, the efficient cleaning and disinfecting procedures are the main requirements because many food pathogenic and spoilage bacteria are able to attach to food contacting surfaces [3,4,5]. Moreover, they might still remain viable even after cleaning and disinfection which might lead to food contamination [2,4,[6][7][8]. Among many reasons causing food contamination, microbial biofilm is important.…”

Abstract:Adhering microflora profile is essential for the development and design of cleaning and sanitizing procedures, which is a part of the HACCP system. The profile provides a complete view of the target microorganisms that can potentially contaminate food products. The aim of this study is, therefore, focused on examination of microbial population adhered to the equipment surfaces at seafood processing plant. Adhering microflora was evaluated by installing the stainless steel coupons on the surface of equipment. Seventy stainless steel coupons were attached on 7 different locations at seafood processing plant and then fourteen coupons were collected at 1, 2, 3, 5 and 9 weeks interval. The population of bacteria adhered on samples were enumerated using swab test and spread plate method on different selective microbiological media. The total viable count and Pseudomonas spp. population found on the stainless steel coupons were ranged from 10 1 to 10 6 cfu/cm 2 . The results also indicated that mature biofilm might form at some locations after three weeks. After 5 weeks, the highest viable bacterial population (10 6 cfu/cm 2 ) was observed on the stainless steel coupons attached in the trolley used for carrying the soup. These finding supported that the appropriate cleaning and sanitizing procedure should be strictly applied to assure safety in food processing plant.
