The aim of this study was to survey the microbial levels of food contact surfaces in hotels. Microbiological levels of 4611 surfaces (chopping machines, kitchenware, knives, worktops, and cutting boards) from 280 different facilities in Spain were determined in a 3-year period. The contact-plate technique was used throughout the survey. Overall, th...

Several vomiting episodes were reported in December 2007 by the management of a beach club in Calvià. The subsequent case investigation confirmed tuna fish consumption a few hours before onset of emesis in all cases. Microbiological analyses detected high bacterial levels in ready-to-eat fish samples, indicating inappropriate cooking procedures. Mo...

... In this practice, it is essential to include a range of prevention services or even crisis prevention measures (Choi and Kim 2016) that can fully cover the management of the outbreak, which should help to avoid reaching a crisis stage. As part of prevention services, the foremost example is having structured isolation management in place, which is more practical at smaller scales of various range (Anderson 2009;Risa et al. 2009;Doménech-Sánchez et al. 2020) even though it can get prolonged and costly (Danial et al. 2016). At the city level, it is important to have a systematic investigation planning in place (Korte et al. 2016), which can increase the efficiency of monitory and detection methods. ...
... Pieces of equipment, especially cutting boards have a crucial role with respect to cross-contamination. It was found that more than 50% of selected cutting boards used in hotels in Spain had been contaminated with superfluous levels of microorganisms (Doménech-Sánchez et al., 2011). The number of correct responses given to questions about cross-contamination is higher than in the other food safety areas in the current study, even though this rate is still unsatisfactory and there is still a high risk of cross-contamination. ...
... Hal ini memberikan peluang spora bakteri yang tahan panas bergerminasi menjadi sel vegetatif dan memproduksi toksin emetik ataupun enterotoksin (Houška et al., 2007). B. cereus dapat mengontaminasi pangan mentah, misalnya ikan (Doménech-Sánchez et al., 2011) dan pangan yang mengandung pati, misalnya nasi (Martinelli et al., 2013). B. cereus juga dapat tumbuh di pangan yang berasam rendah, karena spora bakteri ini tahan terhadap asam (Ceuppens et al., 2012) ...
