Furthermore, food poisoning cases among rural communities have been rising in recent years. However, the health-related mobile application is a promising tool in improving food poisoning prevention knowledge, attitude, practice, and perception (KAP2) among consumers. Therefore, the current study developed a novel smartphone app, MyWarung\u00a9, and determined its efficacy in increasing awareness, attitude, practice, and perception of food poisoning and its prevention when dining out, especially among rural consumers. (2) Methods: A quasi-experimental pre-and post-intervention study with a control and intervention group were performed on 100 consumers in Terengganu. (3) Results: The intervention\u2019s inter-group outcomes were analysed using the Mann\u2013Whitney test, while the within-group effects were ascertained using the Wilcoxon sign rank test via the SPSS software. It was found that the control group had higher median scores in knowledge (30.0, IQR 7.0), attitude (46.0, IQR 5.0), and practice (34.0, IQR 3.0) than the intervention group before intervention. After the intervention programme, the intervention group showed significant improvement in food poisoning knowledge (p = 0.000), attitude (p = 0.001), and practice (p = 0.000). However, the intervention group\u2019s perceived barriers (p = 0.129) and susceptibility (p = 0.069) and the control group\u2019s perceived barriers (p = 0.422) did not show any significant improvement. (4) Conclusion: The findings indicated that the MyWarung\u00a9 mobile app usage enhanced the food poisoning knowledge, preventive attitude, and practice among consumers when dining out.<\/jats:p>","DOI":"10.3390\/ijerph181910294","type":"journal-article","created":{"date-parts":[[2021,9,30]],"date-time":"2021-09-30T00:03:42Z","timestamp":1632960222000},"page":"10294","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Effect of Smartphone App\u2019s Intervention on Consumers\u2019 Knowledge, Attitude, Practice, and Perception of Food Poisoning Prevention When Dining Out at Selected Rural Areas in Terengganu"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8538-9814","authenticated-orcid":false,"given":"Nur Afifah Mursyida","family":"Zaujan","sequence":"first","affiliation":[{"name":"Faculty of Fisheries and Food Science, Universiti Malaysia Terengganu, Kuala Nerus 21030, Terengganu, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4400-6749","authenticated-orcid":false,"given":"Asma\u2019","family":"Ali","sequence":"additional","affiliation":[{"name":"Faculty of Fisheries and Food Science, Universiti Malaysia Terengganu, Kuala Nerus 21030, Terengganu, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5591-3315","authenticated-orcid":false,"given":"Malina","family":"Osman","sequence":"additional","affiliation":[{"name":"Department of Medical Microbiology and Parasitology, Faculty of Medicine and Health Sciences, Universiti Putra Malaysia, Serdang 43400, Selangor Darul Ehsan, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5033-627X","authenticated-orcid":false,"given":"Hui Yee","family":"Chee","sequence":"additional","affiliation":[{"name":"Department of Medical Microbiology and Parasitology, Faculty of Medicine and Health Sciences, Universiti Putra Malaysia, Serdang 43400, Selangor Darul Ehsan, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9093-4354","authenticated-orcid":false,"given":"Nur Raihana","family":"Ithnin","sequence":"additional","affiliation":[{"name":"Department of Medical Microbiology and Parasitology, Faculty of Medicine and Health Sciences, Universiti Putra Malaysia, Serdang 43400, Selangor Darul Ehsan, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3488-0280","authenticated-orcid":false,"given":"Norashiqin","family":"Misni","sequence":"additional","affiliation":[{"name":"Department of Medical Microbiology and Parasitology, Faculty of Medicine and Health Sciences, Universiti Putra Malaysia, Serdang 43400, Selangor Darul Ehsan, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0974-7074","authenticated-orcid":false,"given":"Surianti","family":"Sukeri","sequence":"additional","affiliation":[{"name":"Department of Community Medicine, School of Medical Sciences, Universiti Sains Malaysia, Kota Bharu 16150, Kelantan, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9009-2049","authenticated-orcid":false,"given":"Christie Pei-Yee","family":"Chin","sequence":"additional","affiliation":[{"name":"Faculty of Computing and Informatics, Universiti Malaysia Sabah, Kota Kinabalu 88300, Sabah, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,9,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"232","DOI":"10.4103\/JPBS.JPBS_141_18","article-title":"Knowledge, attitude, and practice toward food poisoning among food handlers and dietetic students in a public university in Malaysia","volume":"10","author":"Yusof","year":"2018","journal-title":"J.
