In response, government initiatives have been implemented to inform consumers of ways to safely handle food. The aim of this study was to examine the accuracy of prompted and unprompted recall of messages from a safe food-handling media campaign in Western Australia, and whether this accuracy of prompted and unprompted recall differed by demographic factors and the mode of delivery of the campaign materials.Design/methodology/approachSurvey responses from 121 participants (Mage = 47.15 years, SD = 15.52) who reported seeing or hearing the campaign were analysed. A series of chi-square tests were used to determine the accuracy of recall when prompted and unprompted, and the accuracy of unprompted and prompted recall across demographic factors and mode of delivery.FindingsResults indicated that more participants accurately recalled the campaign messages when prompted (66.1%) compared to unprompted (35.5%), when they...

A recent safe food-handling media campaign was piloted in Busselton, Western Australia, and was found to lead to improvements in half of the safe food-handling behaviours targeted;however, safe food-handling knowledge did not increase. Consequently, the mechanisms underlying this behaviour change remain unknown. Therefore, the aim of the present study was to determine the mechanisms of behaviour change observed as a result of the pilot safe food-handling media campaign. Data from 117 participants who indicated whether or not they recalled the media campaign advertisements were analysed. Measures of perceived risk related to safe food-handling, safe food-handling habit, and safe food-handling behaviour were collected prior to and following the pilot safe food-handling media campaign. Mediation analyses were conducted to determine if the media campaign advertisements predicted change in behaviour via the change in perceived risk and habit. Results indicated that perceived risk and habit play an important role in safe food-handling behaviour change. These findings have implications for content development of future public health messages related to safe food-handling.

Recent reports indicate that food poisoning is increasing, particularly in Queensland and Western Australia. Foodborne illness is preventable through simple household behaviours such as cleaning hands and surfaces when preparing food, separating raw and ready-to-eat foods, cooking food thoroughly, and keeping food at the correct temperature. Several interventions have been developed to raise awareness of these safe food-handling practices; however, the efficacy of large scale interventions has not been evaluated. The aim of the present study was to evaluate the impact of a pilot safe food-handling media campaign that aimed to increase consumer safe food-handling knowledge and behaviour. Five-hundred and forty-six participants completed measures of safe food-handling knowledge and behaviour prior to and following a pilot safe food-handling media campaign that ran for four months in The City of Busselton, Western Australia. A generalised linear mixed model analysis revealed that the pilot media campaign had an effect on consumer engagement in half of the target safe food-handling behaviours. The pilot safe food-handling media campaign also had a statistically significant effect (albeit not clinically significant) on consumer safe food-handling knowledge, in the oppostite direction to that hypothesised. Findings are discussed in relation to the implications for the design and implementation of future public health messages related to safe food-handling.

While Alfuy virus (ALFV), Barmah Forest virus (BFV), Edge Hill virus (EHV), Kokobera virus (KOKV), Murray Valley encephalitis virus (MVEV), Sindbis virus (SINV), Ross River virus (RRV), Stratford virus (STRV), and West Nile virus strain Kunjin (KUNV) have been associated with human infection, there remains a paucity of data regarding their respective transmission cycles and any potential nonhuman vertebrate hosts. It is likely that these viruses are maintained in zoonotic cycles involving native animals rather than solely by human-to-human transmission. A serosurvey (n = 100) was undertaken to determine the prevalence of neutralizing antibodies against a panel of Australian arboviruses in western gray kangaroos (Macropus fuliginosus) obtained from 11 locations in the midwest to southwest of Western Australia. Neutralizing antibodies against RRV were detected in 25%, against BFV in 14%, and antibodies to both viruses in 34% of serum samples. The prevalence of antibodies against these two viruses was the same in males and females, but higher in adult than in subadult kangaroos (p < 0.05). Twenty-one percent of samples had neutralizing antibodies against any one or more of the flaviviruses ALFV, EHV, KOKV, MVEV, and STRV. No neutralizing antibodies against SINV and KUNV were detected. If this sample of kangaroo sera was representative of the broader Australian population of macropods, it suggests that they are common hosts for RRV and BFV. The absence or low seroprevalence of antibodies against the remaining arboviruses suggests that they are not prevalent in the region or that kangaroos are not commonly infected with them. The detection of neutralizing antibodies to MVEV requires further investigation as this virus has not been identified previously so far south in Western Australia.

Knowledge, attitudes, and practices (KAP) in relation to mosquitoes and mosquito-borne disease have not yet been investigated within Australia. A randomized telephone survey of 2,500 households across 12 regions in WA was undertaken between February and May 2014. The aim of the survey was to obtain baseline KAP data surrounding mosquitoes and mosquito-borne diseases in different regions of WA, across a range of age groups and between males and females. The results of this survey indicate that the majority of respondents are aware of the potential for mosquitoes in WA to transmit Ross River virus, while awareness of other endemic mosquito-borne diseases remains limited. Common misconceptions exist in relation to exotic mosquito-borne diseases, with respondents incorrectly identifying malaria and dengue as endemic diseases in WA.

Ross River virus (RRV) is the most common cause of mosquito-borne illness in Western Australians.... more Ross River virus (RRV) is the most common cause of mosquito-borne illness in Western Australians. The virus is maintained in nature principally via transmission between competent mosquito vectors and native (marsupial) vertebrate hosts, although humans are suspected of being amplifiers of RRV in some situations. The influence of prevailing environmental conditions on the ecology of RRV has been extensively documented. Indeed, monitoring of environmental variables, together with vector mosquito populations and infection rates with RRV, now provides effective early warning of elevated levels of RRV activity in several different regions of Australia. Serosurveys provide convincing evidence that western grey kangaroos (WGK; Macropus fuliginosus) are commonly infected with the virus in south-west coastal regions of Western Australia. There is also evidence of seroconversions in WGKs coinciding with outbreaks of human disease. Such outbreaks have been preceded by favourable environmental ...

Common misconceptions exist in relation to exotic mosquito-borne diseases, with respondents incorrectly identifying malaria and dengue as endemic diseases in WA. The survey also highlighted a range of important issues, such as limited awareness of the potential for backyard breeding in domestic containers, occupational exposure to mosquitoes in regions with a large employment base in the mining and resources sector, increased exposure to mosquitoes as a result of participation in outdoor recreational activities in the north of the State, and reduced awareness of mosquito-borne disease in individuals aged 18–34 years. The results of this study will be used to inform the development of a new communication strategy by the Department of Health, to further raise awareness of mosquito-borne disease in WA. The data will then provide a baseline against which to compare future survey results, facilitating the rigorous evaluation of new communication efforts.

Given the close association between kangaroos, livestock, and humans and the growing popularity of kangaroo meat, it is important to identify epidemiologic factors associated with infection in these marsupials in order to minimize the risk of Salmonella transmission. The overall prevalence of fecal Salmonella in 645 western grey kangaroos (Macropus fuliginosus) sampled across 10 locations in Western Australia was 3.6% (95% CI: 2.3–5.3). Seven Salmonella serovars were identified including Salmonella enterica serovar Muenchen, Kiambu, Rubislaw, Lindern, Champaign, Saintpaul and II 42:g,t:-. Prevalence was significantly associated with rainfall (P,0.05) and was highest in the April– June quarter (P,0.05). There was no association between age or sex and the prevalence of Salmonella in fecal samples. Our results suggest that, while kangaroos are infected with Salmonella in their natural habitat, infection is less common than in hand-reared joeys, pet kangaroos, and macropods raised in captivity. Care should be taken to maintain hygiene during the evisceration, processing, and handling of kangaroos and to adequately cook kangaroo meat prior to consumption to reduce the risk of salmonellosis.
