Studies & Degrees in Food Hygiene

Food hygiene covers everything that keeps food safe from the farm to the plate. European Union law defines it as the measures and conditions necessary to control hazards and to ensure that a foodstuff is fit for human consumption. In practice this means clean premises and equipment, personal hygiene, correct cooking and storage temperatures, separating raw and cooked food, controlling allergens, and keeping records that show the rules are followed.

The stakes are high. The World Health Organization (WHO) states that unsafe food can cause more than 200 different diseases, and its fact sheet of June 2026 estimates that 866 million people fall ill after eating contaminated food and 1.52 million die every year.

What students learn

  • food microbiology: the bacteria, viruses and parasites that contaminate food and the conditions in which they grow
  • chemical and physical hazards, and allergens
  • personal hygiene, cleaning and disinfection, pest control
  • temperature control, the cold chain and storage
  • HACCP (hazard analysis and critical control points), the method used to identify hazards and the steps where they must be controlled
  • traceability, labelling, and food law and inspections

Qualifications and levels

Food hygiene is taught at very different levels, from a course of a few hours to a doctorate.

  • Food handler training. This is the basic level for anyone who works with food in hospitality, retail or industry. In the European Union, food business operators must ensure that food handlers are supervised and instructed or trained in food hygiene in line with their work. In Spain, the rules that required officially authorised food handler courses (Real Decreto 202/2000) were repealed by Real Decreto 109/2010, which moved the responsibility for training to the food businesses. Courses are therefore offered by private providers, and the certificate is issued by the provider. One example is the Curso de Manipulador de Alimentos of ACEDIS Formación: an online course with an estimated duration of 20 hours, with variants by activity such as hospitality, transport and retail. In the United Kingdom, the government's guidance for food businesses likewise tells them to train all their staff.
  • HACCP and supervisor courses. People who design or maintain a company's food safety system need more advanced training. EU law requires food businesses to keep permanent procedures based on the HACCP principles, and those responsible for them must be trained in applying these principles.
  • Vocational training. In Spain, the higher vocational qualification Técnico Superior en Procesos y Calidad en la Industria Alimentaria takes 2,000 hours, and its career profiles include managing food safety.
  • University degrees. Food hygiene is a core subject of degrees in food science and technology, nutrition and dietetics, and veterinary medicine. In Spain, a bachelor's degree (grado) has 240 ECTS credits and master's degrees have 60, 90 or 120 ECTS credits; there are master's programmes in food safety and quality.

Where to study

SpainExchange lists 3 active schools for food hygiene: 2 in Spain and 1 in the United States. The Spanish providers offer short professional courses, often online and in Spanish. In the United States, Tennessee Tech University has a College of Agriculture and Human Ecology with 19 programmes of study, among them food, nutrition and dietetics.

Rules differ by country, so choose a course that matches the place where you will work. The European Union applies one regulation on the hygiene of foodstuffs in all member states. In the United States, the Food and Drug Administration publishes the Food Code, a model that local, state, tribal and federal regulators use to write their own food safety rules. International standards are set by the Codex Alimentarius, founded in 1963 by the FAO and the WHO.

Before enrolling in a short course, ask the school what recognition the certificate has, whether employers and inspectors in your sector accept it, and how often the training should be renewed.

Careers

A food handler course is a requirement for many jobs in kitchens, catering, shops and food factories, not a career in itself. With vocational or university studies, graduates work as quality control and laboratory technicians, food safety and HACCP managers, auditors and consultants, and official food inspectors.

In the United States, the Bureau of Labor Statistics states that agricultural and food science technicians typically need an associate's degree, and agricultural and food scientists at least a bachelor's degree. It projects employment to grow 5 percent for the technicians and 6 percent for the scientists from 2025 to 2035.

Frequently asked questions

Is a food handler certificate compulsory in Spain?

The law does not require a specific official certificate. Since Real Decreto 109/2010, food businesses are responsible for making sure that their food handlers are trained in food hygiene, and a course certificate is the usual way to show it.

How long does a food hygiene course take?

Basic food handler courses are short: the online course of ACEDIS Formación has an estimated duration of 20 hours. The Spanish higher vocational qualification in food industry processes and quality takes 2,000 hours, and a bachelor's degree has 240 ECTS credits.

What is HACCP?

HACCP stands for hazard analysis and critical control points. It is a method to identify the hazards in a food process and the steps where they must be controlled. EU law requires food businesses to have procedures based on its principles.

Is a certificate from one country valid in another?

Not automatically. Food safety rules and training requirements are set by each country or, in the United States, by state and local regulators. Ask the school and your future employer what recognition the certificate has.
