Tsakalidis Labs

Tsakalidis Analysis & Testing (legally registered as Α. Τσακαλίδης Ε.Ε.) is an independent analytical laboratory headquartered at Tsamadou 12, Piraeus 185 31, Greece, serving clients across the food and beverage, water, environmental, agricultural, pharmaceutical, and cosmetics industries. Operating under the motto "Testing your way to safety," the laboratory's mission is to deliver reliable and accurate analyses that generate actionable results supporting clients' business decisions. With eight specialized internal departments and a multidisciplinary team of scientists and technicians, Tsakalidis Analysis & Testing provides a comprehensive analytical service from sample collection through to final reporting, all within a formally structured quality management framework.

The laboratory's primary testing domains span five core sectors: food and beverages, drinking and process water, environmental matrices, agricultural products and inputs, and pharmaceutical and cosmetic products. Within each domain the laboratory performs physical, chemical, and microbiological analyses on a wide range of sample types, applying officially accepted methodologies and internationally recognized standards. This breadth allows a single laboratory relationship to cover multiple compliance, quality assurance, and research testing needs across a client's supply chain, making Tsakalidis a versatile partner for manufacturers, producers, processors, and regulators alike.

Microbiological analysis is a significant area of expertise at Tsakalidis Analysis & Testing. The laboratory tests ready-to-eat foods for pathogenic microorganisms including Listeria monocytogenes in full compliance with European Commission Regulation (EC) No 2073/2005 on microbiological criteria for foodstuffs. The laboratory assists food business operators in demonstrating to competent authorities whether their ready-to-eat products support or inhibit the growth of L. monocytogenes—a critical due-diligence requirement under EU food safety law. Broader microbiological testing services extend to water quality monitoring, environmental surface swabbing, and pharmaceutical microbiology, supporting clients wherever microbiological risk management is required.

Chemical and physical testing at Tsakalidis covers environmental contaminants, food quality parameters, and food contact materials (FCM). The laboratory has demonstrated expertise in the determination of intentionally added substances (IAS) and non-intentionally added substances (NIAS) in food contact materials—including plastic packaging, household and industrial utensils, storage equipment, and food preparation surfaces—supporting compliance with EU regulations on materials and objects intended to contact food. This capability is directly relevant to the circular economy agenda for packaging materials and the supply chain compliance obligations of food manufacturers and packagers. The laboratory presented work on IAS and NIAS determination methodologies at the 8th National Metrology Conference (METROLOGY22), evidencing active scientific engagement at the forefront of food contact material analysis.

Tsakalidis Analysis & Testing holds testing accreditation certificate No. 16 from ESYD (Hellenic Accreditation System — Εθνικό Σύστημα Διαπίστευσης), Greece's national accreditation body and a full member of EA (European co-operation for Accreditation) and a signatory to the Multilateral Agreement (MLA). This accreditation confirms conformance to ISO/IEC 17025, the international standard for the competence of testing and calibration laboratories, providing clients with internationally recognized assurance of measurement competence and analytical result validity. All analyses are conducted according to officially accepted and validated methodologies, ensuring that test reports carry full weight with regulatory authorities, certification bodies, and trading partners throughout the European Union and internationally.

The laboratory's organizational structure reflects a strong commitment to client service quality across all eight dedicated departments: general management, technical direction (laboratory operations led by a named Technical Director), operational management, commercial direction, sampling logistics, sample reception, reporting, and accounting. The sampling department offers field collection services for environmental, water, and food matrices, ensuring chain-of-custody integrity from point of collection to the analytical bench. The dedicated reporting team ensures that certificates of analysis are prepared to the standards required by regulatory bodies and commercial customers. Operating hours are Monday through Friday, 08:00 to 16:00 Greek time, with named specialists available for commercial inquiries, technical questions, sampling coordination, and result delivery.

Tsakalidis Analysis & Testing actively participates in the broader food industry, water research, and packaging science communities, reinforcing its standing as a credible and engaged testing partner. The laboratory was Bronze Sponsor of the 2022 Marine and Inland Waters Research Symposium, demonstrating commitment to water monitoring science. In the food sector, the laboratory supported the inaugural Food Experts Awards (FEA 2023) at the DETROP International Food and Beverage Exhibition—an international innovation and excellence program organized in Greece for the first time in 2023—as well as the SYSKEVASIA22 packaging trade event. This consistent participation across scientific conferences, metrology congresses, and industry exhibitions confirms that Tsakalidis Analysis & Testing is both technically current and commercially engaged across the full breadth of its testing disciplines.
