Consumer perspectives on the inclusion of nutritional warnings in retail food establishments

ABSTRACT The present work aimed to assess Uruguayan consumers support of the inclusion of nutritional warnings on four types of retail food establishments and to obtain consumer insights on how the warnings could be implemented in such establishments. For this purpose, an online survey was conducted with a non-probabilistic sample of 547 participants recruited via an advertisement on social media. Participants were requested to indicate their degree of agreement with the implementation of nutritional warnings in bakeries, delicatessens, fast-food restaurants and while ordering food online, and to provide ideas on how to include this information for each establishment. Results suggested that the inclusion of nutritional warnings in retail food establishments was positively perceived by participants. Participants highlighted that warnings should be highly visible to customers while making purchase decisions, so they become a relevant cue for making food choices. In particular, the retail display case and menu boards were identified as key locations for warnings in bakeries, delicatessen, and fast food restaurants, respectively. These results contribute valuable insights on how to implement the extension of nutritional warnings to unpackaged foods or foods made and packaged at the point of purchase.

RESUMEN El presente trabajo tuvo como objetivo evaluar la percepción de los consumidores uruguayos en relación a la implementación de advertencias nutricionales en cuatro puntos de venta de comida y generar ideas sobre cómo podría implementarse esta medida. Se realizó un estudio online con una muestra no probabilística de 547 participantes, reclutados utilizando publicidad en redes sociales. Los participantes indicaron su grado de acuerdo con la implementación de advertencias nutricionales en panaderías, rotiserías, lugares de venta de comida rápida y sitios de pedidos online, y proporcionaron ideas sobre cómo incluir esta inforamción en cada punto de venta. Los resultados sugieren que la población tiene una perecpeción positiva sobre la inclusión de advertencias nutricionales en puntos de venta de comida. Los participantes destacaron la importancia de incluir esta información en un lugar visible al momento de elegir los productos, de forma que pueda ser tenida en cuenta al tomar las decisiones. En particular, las vitrinas y la cartelería/pizarras fueron identificados como lugares estatégicos para la inclusión de advertencias nutricionales en panaderías/rotiserías y puntos de venta de comida rápida, respectivamente. Los resultados proporcionan valiosa información para extender la inclusión de advertencias nutricionales a puntos de venta de comida.

Genotypic Characterization of Methicillin-resistant Staphylococcus aureus Isolated from Pigs and Retail Foods in China / 生物医学与环境科学（英文）

<p><b>OBJECTIVE</b>To investigate the genotypic diversity of Methicillin-resistant Staphylococcus aureus (MRSA) isolated from pigs and retail foods from different geographical areas in China and further to study the routes and rates of transmission of this pathogen from animals to food.</p><p><b>METHODS</b>Seventy-one MRSA isolates were obtained from pigs and retail foods and then characterized by multi-locus sequencing typing (MLST), spa typing, multiple-locus variable number of tandem repeat analysis (MLVA), pulsed-field gel electrophoresis (PFGE), and antimicrobial susceptibility testing.</p><p><b>RESULTS</b>All isolated MRSA exhibited multi-drug resistance (MDR). Greater diversity was found in food-associated MRSA (7 STs, 8 spa types, and 10 MLVA patterns) compared to pig-associated MRSA (3 STs, 1 spa type, and 6 MLVA patterns). PFGE patterns were more diverse for pig-associated MRSA than those of food-associated isolates (40 vs. 11 pulse types). Among the pig-associated isolates, CC9-ST9-t899-MC2236 was the most prevalent clone (96.4%), and CC9-ST9-t437-MC621 (20.0%) was the predominant clone among the food-associated isolates. The CC9-ST9 isolates showed significantly higher antimicrobial resistance than other clones. Interestingly, CC398-ST398-t034 clone was identified from both pig- and food-associated isolates. Of note, some community- and hospital-associated MRSA strains (t030, t172, t1244, and t4549) were also identified as food-associated isolates.</p><p><b>CONCLUSION</b>CC9-ST9-t899-MC2236-MDR was the most predominant clone in pigs, but significant genetic diversity was observed in food-associated MRSA. Our results demonstrate the great need for improved surveillance of MRSA in livestock and food and effective prevention strategies to limit MDR-MRSA infections in China.</p>
