Food Loss and Waste (FLW) that entail substantial economic, environmental, and social cost is of great concern for a country fulfilling > 80% of food demands through the import of agricultural commodities. The current study mainly aimed at bringing together a wide range of perspectives on FLW by multi-stakeholder engagement in order to enhance cooperation and network building with respect to sharing knowledge and experiences on FLW prevention activities along the entire food supply chain for a country located at the geographic frontier facing stubborn challenges of desertification, water scarcity, and harsh climatic conditions. These challenges are not only being addressed at the national level but have also been made the focus of multilateral activities in 2020 as part of the Saudi G20 Presidency. The Ministry of Environment, Water and Agriculture under the umbrella of the G20 Meeting of Agricultural Chief Scientists (MACS) hosted a regional workshop on FLW in collaboration with the Thünen Institute, Germany, to raise awareness among Gulf Cooperation Council (GCC) countries. The present paper provides insights into the current status of FLW by revealing that, overall, 33.1% of the total available food in the Kingdom is lost and wasted during the entire food supply chain. Overall, the GCC countries witnessed higher percentages of food waste compared with food losses. Environmental conditions prevailing in the region necessitate the development of adequate and appropriate cold chain storage facilities for balanced distribution through cold storage transportation facilities along the food supply chain to minimize food losses. However, campaigns and activities to raise awareness with a view of changing attitudes towards reducing FLW by the adoption of good practices, promoting the concept of circular economy practices, and the establishment of food banks for surplus food redistribution are important to mitigate FLW in the Kingdom.

In recent years, there has been a significant increase related to pesticide residues in foods, which may increase the risks to the consumer of these foods with the different quality and concentrations of pesticide residues. Pesticides are used for controlling pests that reduce yields. On the other hand, it has become a major public health concern due to its toxic properties. Thus, the objective of the current study employed the application of Quick Easy Cheap Effective Rugged Safe (QuEChERS) method, in combination with gas and liquid chromatography-tandem mass spectrometric detection (GCMSMS, LCMSMS) in order to determine 137 pesticide residues (63 insecticides, 41 acaricides, 40 herbicide, 55 fungicide, nematicide, growth regulator, Chitin synthesis inhibitors, and Juvenile hormone mimics), in 801 vegetables such as 139 tomatoes, 185 peppers, 217 squash, 94 eggplants, and 166 cucumbers from different locations in Hail and Riyadh cities. The results showed that the majority of pesticide residues were detected for each of the following pesticides: acetaimpride, metalaxyl, imidaclopride, bifenthrin, pyridaben, difenoconazole, and azoxystrobien, which were repeated in the samples studied 39, 21, 11, 10, 8, 7, and 5, respectively. In addition, results observed that the tomato was the most contaminated with pesticide residues; it was contaminated with 19 compounds and was followed by pepper, cucumber, and squash, and the last commodity in the contaminated ranking was eggplant. The highest calculated estimated daily intakes (EDIs) were recorded for tomatoes which were estimated between 0.013 to 0.516 mg/kg of body weight per day (bw/day) while the lowest EDIs value was between 0.000002 to 0.0005 mg/kg of bw/day for cucumber. Results indicated that the EDIs values were lower than the acceptable daily intake (ADI) values. Results observed that the most of pesticide residues exposure in food consumption in Saudi Arabia were lower than ADIs. In addition, the highest value for health risk index (HRI) was recorded with Ethion residue in tomato, but in sweet pepper, the highest value for HRI was 127.5 in the form of fipronil residue. On the other hand, results found that the highest values of HRI were 1.54, 1.61, and 0.047 for difenoconazole, bifenthrin, and pyridaben residues in squash, eggplant, and cucumber.
