Aflatoxin B1 (AFB1), a hepatocarcinogenic metabolite produced by certain strains of Aspergillus section Flavi, is one of the major contaminants in red chili products that affect human health. This study determined the level of AFB1 in chili traded in Oman. In addition, a survey was conducted among 260 respondents to assess consumers’ knowledge and awareness of aflatoxin contamination in chili. A competitive enzyme-linked immunosorbent assay (ELISA) was performed on 58 samples of dried red chili pods, red chili flakes, and red chili powder collected from various markets in Oman. The ELISA results showed the presence of AFB1 in all the samples analyzed. None of the dried red chili pod samples exceeded 10 ppb AFB1, the maximum permissible limit adopted by the Oman Legislation for foods, whereas a few red chili flakes and red chili powder samples exceeded 10 ppb. However, AFB1 content in all the samples was below the maximum tolerance limit of 20 ppb set by the U.S. Food and Drug Administration. The survey results revealed that most respondents were unaware of aflatoxins, as education, gender, and social media were found to be significant determinants of aflatoxin awareness. This study provides valuable insights into the level of AFB1 contamination in red chili products, raises the need for aflatoxin awareness in Oman, and urges for safe culinary practices in the region.

The Indian Ocean Rim Association (IORA) is a regional association based on the principle of open regionalism to promote liberalization through trade and investment facilitation. This study compares two main scenarios with the ingredients of a deeper regional integration compared to the IORA's present open regionalism status. Scenario I evaluates the effects of gradual tariff cuts on IORA, while Scenario II combines the impact of tariff cuts, non-tariff measures (NTM) reduction, and trade facilitation. A recent recursive dynamic model, called Global Trade Analysis Project recursive dynamic model (GTAP-RD), was used to understand the adjustment path. The result shows welfare gain for all IORA countries when a trade liberalization involving tariff cuts is complemented with NTM reduction and trade facilitation. In addition, the "NTM spillover" effect on some non-IORA members (the rest of Gulf Cooperation Council, the rest of Greater Arab Free Trade Agreement, and the United Kingdom) was observed. The results suggest that IORA has more to gain if it involves a deeper regional integration than the present form of open regionalism.
