Securing food safety standards is crucial to protect the population from health-threatening food contaminants. In the case of pesticide residues, reference procedures typically find less than 1% of tested samples being contaminated, thus indicating the necessity for new tools able to support smart and affordable prescreening. Here, we introduce a hybrid paper–lab-on-a-chip platform, which integrates on-demand injectors to perform multiple step protocols in a single disposable device. Simultaneous detection of enzymatic color response in sample and reference cells, using a regular smartphone, enabled semiquantitative detection of carbofuran, a neurotoxic and EU-banned carbamate pesticide, in a wide concentration range. The resulting evaluation procedure is generic and allows the rejection of spurious measurements based on their dynamic responses, and was effectively applied for the binary detection of carbofuran in apple extracts.

Tofu is a high-protein soy-based food ingredient that is widely consumed in Indonesia. Tofu producers in Delta Pawan Subdistrict are dominated by small and medium-sized entrepreneurs whose hygiene and sanitation aspects in production activities are very under-taken. This study aims to determine the presence of Coliform and Salmonella Sp bacteria on tofu produced in Delta Pawan sub-district, Ketapang, West Kalimantan and compare with SNI01-3142-1998. The method used to detect the presence of Coliform bacteria in this study uses the Most Probable Number (MPN) method, which consists of estimator and confirmatory tests using Lactosa Broth (LB) media for the Brilliant Green Lactose Broth (BGLB) assay test for confirmation . Whereas to detect the amount of Salmonella Sp using the method of Total Plate Count (TPC) with selective media Salmonella Shigella Agar (SSA). The results of Coliform analysis in both industries found Coliform MPN values ​​of more than 2400 AMP / g samples, which indicated that they did not meet the standards set by SNI. While the results of the analysis of Salmonella Sp obtained positive results, so the two industries did not meet food safety standards.

This study clarifies the changes in the trade of fish-related commodities (FRC) between Turkey and Japan, and discusses the outlook of such trade. Turkeys ability to adapt to the international food-safety standards enabled it to export primary commodities to the region. Turkey can draw from its EU experience when exporting primary products to Japan. Fisheries trade between Turkey and Japan has increased significantly in the past decade, from just over US$12 million (2,404 tons) in 2000 to more than US$49 million (3,653 tons) in 2011. From our interviews, we found that (1) there are significant fish-related trade opportunities between the two countries; (2) addressing the lack of knowledge or factual information in general is the most important task for increasing such fisheries trade; and (3) communication initiatives such as advertising, exhibitions, and field trips are necessary to increase the countries basic understanding of each others fisheries sector. In conclusion, detecting and capitalizing on new potential (FRC) (e.g., Atlantic bonito, Pacific saury, and sardine) in accordance with the preference of the market could be a new strategy that would promote further development of trade between the two countries.


The article examines the features of the Hazard Analysis and Critical Control Points (HACCP) system as a factor in food safety. The principles of HACCP, formulated in the ISO 22000: 2005 standard, in the Alimentations Commission Codex are compared, as well as in accordance with the Ukrainian regulatory document "Requirements for the development of food safety standards", approved by the Order of the Ministry of Health of Ukraine on October 1, 2012 No. 590. The comparison is carried out in order to establish the compliance of the Ukrainian HACCP system with the international rules, in particular the ISO 22000: 2005 standard. Shown, that the principles of the Ukrainian HACCP system generally comply with international standards, in particular ISO 22000: 2005. This means that the legislation of Ukraine guarantees that, in compliance with it, food products originating from Ukraine comply with international requirements for the control of its manufacture. The guarantee of this is the system of control measures that are provided for by the laws of Ukraine regarding compliance with the requirements of the HACCP system.

There have been growing concerns about the effects of food safety standards on agricultural trade throughout the world. One of the food safety standards applied in international trade is the adoption of maximum residue limits of pesticides. This research uses panel gravity model to analyze the effect of maximum residual limit (MRL) of pesticides imposed by importing countries on export of Indonesia’s medicinal plant products. The results show that stringent food safety standards imposed by importing countries have a negative and statistically significant effect on Indonesia’s export of medicinal plant products. The results also show that volume of Indonesia’s medicinal plant products exports are influenced by real GDP of exporter and importer, population, production, economic distance, and ad valorem tariff. Keywords: food safety standard, Gravity model, Panel data, Medicinal plant products.

Island Poteran one of the islands in Sumenep regency which has significant potential in the fisheries sector. In the year 2013, seaweed production amounted to 58027.61 kg with a value of 97,969,555 rupiah annually. But the use of seaweed in Pulau Poteran far only sold in fresh form. Though there are lots of processed plant that has a high sales value so that it can provide value added  The products that can be produced very diverse as seaweed ready though, jellies, candied kelp, and nata de seaweed. Total production is minimal and dependent on demand. Such products cannot penetrate the supermarket because there is no food safety certificate from the ministry of health and the consent of the industry. Packaging products do not meet food safety standards. Through the science and technology to the Community on KWT Putri Tani and KWT Permata District of Talango, then the outcomes expected are as follows: (1) skilled for on KWT Putri Tani and KWT Permata District of Talango in making jelly, candied and nata de seaweed in attractive packaging, (2) the resulting product is the product of jelly, candied and nata de seaweed in beautiful packaging (marketable), (3) Increased sales jelly, candied and nata de seaweed. KWT members apresiasif response and confident enough. The positive reaction was apparent from the members to continue the business of processed plant for domestic industry. After members of the training, participants are motivated to produce and begin to be marketed in the neighborhood. The production of nata de seaweed, dodol and sweets in a sale at some stores around the island Poteran and part of Sumenep.
