Food Hygiene and Safety Division

The Food Hygiene and Safety Division, part of the Chair of Veterinary Biomedicine and Food Hygiene at the Estonian University of Life Sciences, is a competence center in food hygiene and safety in Estonia.

Our mission is to ensure safe and high-quality food in line with the One Health principles.

We create and share knowledge that helps ensure food safety and quality at the stages of food production, processing, and consumption. To achieve this, we conduct high-quality teaching, including lifelong continuing education, and internationally recognized research, collaborating with research and development institutions, laboratories, national food safety organizations, and food production companies.

Our goal is to provide internationally recognized education, development, and research in food hygiene and safety.

Research work

Our applied research focuses on:

  • Microbiological Food Safety: We focus on foodborne pathogens of public health importance (e.g., Campylobacter spp., Listeria monocytogenes, Salmonella enterica, etc.), including molecular epidemiology and antimicrobial resistance studies. We also collaborate with the field of human medicine to investigate the causes of foodborne diseases.
  • Safety and Quality of High-Risk Plant-Based Foods and Meat Alternatives: We assess the microbiological and chemical safety factors and quality of alternative products.
  • Chemical Food Safety: We evaluate the levels of nitrites, nitrates, acrylamide, and furan in food and their potential bioavailability and impact on public health.

Our fundamental research focuses on:

  • Mechanisms of Spoilage Processes in Animal-Derived Foods: We study the intensity and integrated mechanisms of autolytic, microbial, and oxidative processes to develop effective control methods. We focus on the inhibitory and/or promoting effects of natural bioactive compounds in these processes, analyzing their actions or interactions. We use LC-MS/MS-based methods to discover natural compounds and identify suitable plants.
  • Methods for Determining Freshness of Meat and Fish: In collaboration with AS Ldiamon, we are developing an innovative Time-method for assessing the freshness of meat and fish, based on the measurement of ATP autolysis products.

Food Hygiene and Safety Division conducts internationally recognized research and development work in the fields of food hygiene and safety.

Project introduction of TEM-TA52


The selection and consumption of plant-based foods, including meat alternatives, is growing rapidly, but their microbiological and chemical safety has been poorly studied worldwide. This project focuses on assessing the safety and quality of high-risk plant-based foods in Estonia.


Main activities:

  • Defining typical products and risk categories.
  • Analyzing microbiological safety and quality, as well as conducting risk assessments.
  • Conducting molecular biology and antibiotic resistance studies.
  • Analyzing chemical safety: mycotoxins, toxic alkaloids, ATP breakdown products, and oxidation parameters.

The project aims to clarify:

  • Microbiological safety and quality of animal food alternatives.
  • Chemical safety and quality of animal food alternatives.
  • Microbiological safety and quality of plant-based ready meals.
  • Chemical safety and quality of plant-based ready meals.
  • Public health risks associated with the consumption of these food groups.

Collaboration:

The project partner is the State Laboratory Research and Risk Assessment Center (LABRIS).

Outcome:

The research results will help assess public health risks and support the development of preventive and control measures at both the company and national institutional levels.

Project introduction of PRG1441


The project focuses on investigating the antioxidant, anti-autolytic, and antimicrobial properties of plant-based substances to create optimized blends that inhibit the oxidation of polyunsaturated fatty acids and proteins in meat and fish matrices. Additionally, the impact of these blends on the growth of spoilage and pathogenic microbiota is evaluated.
