2024-03-22T07:57:27+00:00

Laboratories play a strategic role in protecting public health by ensuring the quality and safety of drugs, food, and cosmetics. The Centre of National Quality Laboratory of Drugs and Food (CNQLDF), as the central laboratory of the Indonesian Food and Drug Authority (Indonesian FDA), continuously develops reliable, selective, sensitive, and accurate analytical methods (AM) for cosmetic testing in line with advancements in cosmetic formulation technology. However, both the Indonesian FDA and external cosmetic laboratories need more human resources and infrastructure, hindering the development of analytical method and the testing of cosmetic products. Strengthening these laboratories through stakeholder networks is essential. Indonesia actively participates in the ASEAN Cosmetic Testing Laboratories Committee (ACTLC) and the Indonesian Cosmetic Laboratory Network (ICLN). One of the main tasks of CNQLDF is to develop a new ASEAN Cosmetic Method (ACM) for 1,4-Dioxane contaminants in cosmetics. Currently, CNQLDF, along with the Indonesia National Standard Body (INSB), Ministries and External Laboratories, in which together became members of ICLN, harmonized the analytical method of 1,4-Dioxane at the national level, leading to the issuance of the Indonesian National Standard (INS). Both the INS and ACM have main purpose to standardize analytical methods across laboratories, ensure the safety and quality of cosmetic products and enhance national product competitiveness. This study examines method to strengthen pre-market cosmetic surveillance through harmonizing the analytical method of 1,4-Dioxane at the national and ASEAN regional levels, using a qualitative approach based on the Indonesian FDA's internal data and stakeholder information on 1,4-Dioxane testing capabilities.

2023-12-11T08:48:34+00:00

Good food sanitation is one of the main pillars for achieving food security goals. High levels of Staphylococcus aureus in food can indicate poor hygiene and handling practices during food production, processing, or storage. Before testing, the laboratory needs to verify the quantitative method for Staphylococcus aureus to produce valid data to ensure food safety and quality. The Centre of National Quality Laboratory of Drugs and Food, Indonesian Food and Drug Authority (FDA) has never verified the Staphylococcus aureus quantification method based on the latest ISO 16140-3:2021. Following the guidelines established in ISO 16140-3:2021, method verification is accomplished by calculating the Interlaboratory Reproducibility Standard Deviation (S_IR) for implementation validation and the eBias value for verifying the method's suitability for assessing specific food items. This research was conducted to confirm the ISO 6888-1:2021 as the designated reference method for quantifying Staphylococcus aureus in food products. The cheese was utilized as the test food item to verify the implementation of the method. At the same time, several products, including condensed milk, margarine, baby porridge, cassava chips, and ready-to-eat sausage, were examined as challenging food types. Every chosen food item was artificially contaminated with Staphylococcus aureus WDCM 00034. The S_IR value obtained was 0.04 ≤ 2× 0.11 (the lowest mean of SR value from ISO 6888-1:2021), which indicated that the Centre of National Quality Laboratory of Drugs and Food Indonesian FDA was able to implement the method very well. In addition, the eBias value for all types of food tested was below 0.5log10, which showed that the quantitative method for coagulase-positive Staphylococci (Staphylococcus aureus and other types) could be applied in the Centre of National Quality Laboratory of Drugs and Food laboratory for the extensive scope of food.
