Health Professionals' Knowledge and Understanding about Listeria monocytogenes Indicates a Need for Improved Professional Training
ABSTRACT Listeria monocytogenes causes listeriosis, an uncommon but potentially fatal disease in immunocompromised persons, with a public health burden of approximately $2 billion annually. Those consumers most at risk are the highly susceptible populations otherwise known as the immunocompromised. Health professionals have a considerable amount of interaction with the immunocompromised and are therefore a valuable resource for providing appropriate safe food handling information. To determine how knowledgeable health professionals are about Listeria monocytogenes, a nationwide Web-based survey was distributed targeting registered nurses (RNs) and registered dietitians (RDs) who work with highly susceptible populations. Responses were received from 499 health professionals. Knowledge and understanding of Listeria monocytogenes was assessed descriptively. Parametric and nonparametric analyses were used to detect differences between RNs and RDs. The major finding is that there are gaps in knowledge and a self-declared lack of understanding by both groups, but especially RNs, about Listeria monocytogenes. RDs were more likely than RNs to provide information about specific foods and food storage behaviors to prevent a Listeria infection. Notably, neither group of health professionals consistently provided Listeria prevention messages to their immunocompromised patients. Pathogens will continue to emerge as food production, climate, water, and waste management systems change. Health professionals, represented by RNs and RDs, need resources and training to ensure that they are providing the most progressive information about various harmful pathogens; in this instance, Listeria monocytogenes.

ABSTRACT: An online needs assessment survey of healthcare providers was developed and implemented to determine knowledge and attitudes about the benefits and risks of consuming seafood along with how this might impact patient/clientele counseling. Only 6 of the 45 knowledge items queried (13%) met the 80% subject mastery or proficiency with a total knowledge score of 56 ± 18%. Based on this survey, it was found that healthcare providers were less than proficient regarding all knowledge areas for seafood. Understanding of seafood safety and contaminants was low. In addition, while the majority (76%) of healthcare respondents knew the correct recommendation for seafood meals per week, they failed to identify the groups that were targeted by the Food and Drug Administration/Environmental Protection Agency (FDA/EPA) advisory about seafood and mercury and therefore could be providing inaccurate information. Attitudinal responses for 18 items resulted in an overall average score of 3.28 ± 0.47 meaning slightly agree (based on a 5-point Likert scale strongly disagree—strongly agree). While trends showed that it was important to the respondents to provide accurate information (3.78 ± 1.06) about seafood to their patients, they felt more comfortable recommending that their patients follow government advice (3.52 ± 0.91) about both seafood safety and which seafood to eat over other sources. Combined with a low knowledge base, attitudinal responses indicate that there could be a barrier to both outreach education to these healthcare providers and to their patient counseling regarding seafood consumption. Results also showed that a combination of online, science-based, easy to access information with the capability to provide brochure-formatted information would appear to be the best way to communicate seafood safety, nutrition, and health information.Journal of Food Science Education 09/2013; 12(4).

ABSTRACT: Treating intracellular pathogens remains a considerable medical challenge because of the inefficient intracellular delivery of antimicrobials and the frequent emergence of bacterial resistance to therapeutic agents deemed the drugs of last resort. We investigated the capability of antisense peptide nucleic acids (PNAs) conjugated to the (KFF)3K cell penetrating peptide to target RNA polymerase α subunit (rpoA) and RNA polymerase sigma 70 (rpoD) in the intracellular pathogen Listeria monocytogenes. The PNAs tested displayed a concentration dependent inhibition of L. monocytogenes growth in pure culture at the micromolar level and significantly reduced intracellular L. monocytogenes in infected cell culture and Caenorhabditis elegans whole animal model. In vitro, the combined PNAs treatment was synergistic resulting in a clearance of L. monocytogenes at 0.5× the individual PNA concentration. This study demonstrates the potential of anti-rpoA PNA as an antibacterial agent and will provide the basis for improving and developing these PNAs to better target intracellular pathogens like Listeria. This study also establishes C. elegans as a potential model for the screening of PNAs.07/2013; DOI:10.1089/nat.2013.0426

ABSTRACT: During 2009-2010, a total of 1,527 foodborne disease outbreaks were reported by the Centers for Disease Control and Prevention (CDC) (2013). However, in a 2011 CDC report, Scallan et al. estimated about 48 million people contract a foodborne illness annually in the United States. Public health officials are concerned with this under-reporting; thus, the purpose of this study was to identify why consumers and healthcare professionals don't report foodborne illness. Focus groups were conducted with 35 consumers who reported a previous experience with foodborne illness and with 16 healthcare professionals. Also, interviews with other healthcare professionals with responsibility of diagnosing foodborne illness were conducted. Not knowing who to contact, being too ill, being unsure of the cause, and believing reporting would not be beneficial were all identified by consumers as reasons for not reporting foodborne illness. Healthcare professionals that participated in the focus groups indicated the amount of time between patients' consumption of food and seeking treatment and lack of knowledge were barriers to diagnosing foodborne illness. Issues related to stool samples such as knowledge, access and cost were noted by both groups. Results suggest that barriers identified could be overcome with targeted education and improved access and information about the reporting process.International Journal of Environmental Research and Public Health 08/2013; 10(8):3684-714.
