“…The results of the interviews revealed that PPRP was mainly derived from concerns about the environment (e.g., “the materials of takeout are not environmentally friendly”, “The takeout packaging is difficult to degrade and pollutes the environment”, and “the recycling process of packaging waste indirectly pollutes the environment”) and human health (e.g., “plasticizers and other chemicals in takeout packaging are health hazards”), which were in line with the previous studies about packaging risks (Toensmeier, 2020 ; Wang and He, 2021 ; Angnunavuri et al, 2022 ). To delete the irrelevant items and combine the similar ones, there are six items concerning PPRP left to form the initial measurements.…”

“…The production, use, and recycling of plastic packaging are accompanied by environmental pollution. There is evidence that many plastic packaging production enterprises fail to meet environmental protection standards, and lots of carbon emissions are generated (Angnunavuri et al, 2022 ). Additionally, the use of plastic has increased enormously while recycled is very few (Toensmeier, 2020 ), resulting in pollution of rivers and oceans (Toensmeier, 2020 ).…”

With the rapid development of e-commerce and the impact of COVID-19, online takeout has become the first choice of more and more consumers. Previous research has indicated that food packaging is of great significance to marketing performance, yet very little is known about the mechanisms through which food packaging pollution risk affects online takeout consumption. This study proposes an expanded model of the Theory of Planned Behavior (TPB) by incorporating the Concept of Perceived Risk (CPR) to analyze the mechanism of consumers’ packaging pollution risk perception (PPRP) on their purchasing intention toward online takeout. Online survey was performed to collect data from 336 valid respondents in China, which was analyzed using structural equation modeling. The research findings verify the effectiveness of the TPB in the context of Chinese online takeout. Notably, the PPRP of online takeout was found to have a significant negative impact on consumers’ attitudes, subjective norms, and perceived behavioral control (PBC). It was also confirmed that consumers’ attitudes, subjective norms, and PBC regarding online takeout partially mediate the negative relationship between PPRP and purchase intention. In addition, the findings corroborate the granular nuances among three groups concerning consumers’ education level. The results do not only provide suggestions to the online takeout industry but also contribute theoretical value and practical significance for the improvement of sustainable food consumption.

“…Given that some case-control studies failed to report protective effects of bottled water [36, 61, 72] or even showed increased odds [46], similar assumptions can presumably be made for bottled water. Packaged water in LMICs appear to often be of questionable quality, as modelling suggests [103]. However, the JMP categorization does not reflect this actual risk and the possibility of contamination (in its service ladder).…”

Cholera is a significant health risk for low- and middle-income countries (LMIC), and the threat of outbreaks is likely to increase due to climate change. To keep up to date with the link between water quality and cholera, we conducted a systematic review and meta-analysis to update a previous review. We searched Embase, Web of Science and PubMed for literature published between 2016 and 2022. Search terms were consistent with the previous review. Study quality was assessed using Risk Of Bias In Non-randomized Studies - of Exposures (ROBINS-E). Exposures of water were categorized according to the WHO/UNICEF Joint Monitoring Program for Water Supply, Sanitation and Hygiene (JMP) and further divided by the service ladder. Odds ratios were extracted and pooled by performing random-effects meta-analysis. We identified 22 new eligible studies and analysed them together with the 45 studies included in the previous review. Analyses revealed higher odds of cholera when consuming sachet water (OR=1.69, 95% CI: 1.13 to 2.52), unimproved water (OR=2.91, 95% CI: 1.21 to 7.02), surface water (OR=3.40, 95% CI: 2.52 to 4.58), and untreated water (OR=2.51, 95% CI: 2.03 to 3.10). Meanwhile, treating water (OR=0.42, 95% CI: 0.27 to 0.65), by boiling (OR=0.38, 95% CI: 0.17 to 0.84) or chlorination (OR=0.37, 95% CI: 0.17 to 0.83), and drinking basic water (OR=0.44, 95% CI: 0.27 to 0.69) showed protection. Pooled estimates changed with updated evidence while qualitative insights on the protective or risk factors remain valid. Relatively low-cost methods like boiling or chlorinating water provide good protection comparable to providing basic water to the public.

“…This result applied to both forms of packaged drinking water available -sachets and bottles [7]. Other studies have attempted to determine contamination levels of packaged drinking water in different parts of Nigeria and Ghana and have found the presence of heavy metals, and microbial contamination [10,[14][15][16].…”

Sachet water (SW) is a major source of drinking water in most Nigerian homes, thus making it a possible conveyance medium for health risks due to contamination rather than for replenishment of the body. This study collected SW from three busy neighborhoods and investigated for the presence of indicator bacteria – Escherichia coli (E. coli), Total Coliform (TC), Total Heterophilic Bacteria (THB), and Staphylococcus – and some physio-chemical parameters – total dissolved solids (TDS), pH, electrical conductivity (EC), and salinity. Multi-variable and exploratory statistical methods were applied to the results to determine correlations between bacterial contamination levels and perceived brand reputation. Bacteriological test with raw SW samples appeared too numerous to count (TNC) and thus required serial dilutions. After seven dilutions, results obtained revealed that SW brands with good reputation had no TC and E. coli and was statistically significant with groupings of other SW brands (χ2 = 12.28; p < 0.05 and χ2 = 37.96; p < 0.05) respectively. Additionally, SW brands with poor reputation had mean values of TC (19.7X10^8 cfu/ml;14X10^8 cfu/ml1.15X10^8 cfu/ml) and E.coli (18.2X10^8 cfu/ml;38.7X10^8 cfu/ml,32.4X10^8 cfu/ml) exceeding threshold value of zero set by the World Health Organization (WHO). Only one sample from poor reputation brand tested positive for Staphylococcus and was not statistically significant (χ2 =5.2191; p = 0.074). Principal Component Analysis (PCA)/ Factor Analysis (FA) revealed that most of the SW had fecal contamination in an alarming magnitude. Therefore, this study suggests that periodic cleaning of distribution lines, location specific treatment, QC and QA measures should be taken to reduce water security risk for SW consumption in the region.
