Genetic Modification

Genetically modified (GM) foods and other types of novel foods can only be marketed in the European Union if they have passed a rigorous safety assessment.


Novel Foods

A novel food is defined as a food or food ingredient which does not have a significant history of consumption within the EU before May 1997.

All novel foods are subject to a pre-market safety assessment under the novel foods regulation (EC) 258/97. In the UK the ACNFP carries out all novel food assessments.


Risk assessment and authorisation of GM foods

The current procedures for evaluation and authorisation of GM foods are laid down in Regulation (EC) 1829/2003 on GM food and feed, which came into force in April 2004. The safety assessments are carried out by the European Food Safety Authority (EFSA), which published updated guidelines for the assessment of GM plants in March 2005.

Each application is reviewed on a case-by-case basis, including a detailed consideration of the potential for toxic, nutritional and allergenic effects. GM foods may only be authorised for sale if they are judged not to present a risk to health, not to mislead consumers, and not to be of less nutritional value than the foods they are intended to replace.

EFSA is responsible for publishing information concerning applications submitted under this legislation. Further details can be found on the EFSA website.

In carrying out its evaluation, EFSA may consult the authority responsible for food safety assessment in one of the EU Member States. In the UK this is the Food Standards Agency, which seeks expert advice on GM foods from the independent Advisory Committee on Novel Foods and Processes (ACNFP) as appropriate.

When an authorisation is requested that includes cultivation of GM crops for feed or food use, EFSA will consult the national competent authorities designated under Directive 2001/18/EC, which deals with the deliberate release of GMOs to the environment. The Department for Environment Food and Rural Affairs (DEFRA) is the contact point for the UK.

EFSA’s final opinion on each application is published for public comment before any decision on authorisation is taken. Check the European Commission’s website to get the maximum notice of these consultation periods.

The final decision on authorisation rests with Member States, who vote on each GM food at the Standing Committee on the Food Chain and Animal Health. The European Commission maintains a Register of GM food and feed materials that are authorised in the EU.


Labelling

 

In the case of pre-packaged GM food/feed products, European (Regulation (EC) No 1829/2003 and No 1830/2003) requires that the list of ingredients must indicate “genetically modified” or “produced from genetically modified [name of the organism]”. In the case of products without packaging these words must still be clearly displayed in close proximity to the product (e.g a note on the supermarket shelf).

These labelling requirements do not apply to GM food/feed products in a proportion no higher than 0.9 percent of the food/feed ingredients considered individually and if this presence is adventitious or technically unavoidable.Products such as meat, milk and eggs from animals fed on GM animal feed will also not need to be labelled. Details on the labelling rules can be found on the table on the FSA website: www.food.gov.uk/gmfoods/gm_labelling

Biotechnology Chronology

The word “biotechnology” according to the story ‘Banking on Biotech’ (Syracuse Post-Standard, September 29, 2002), first appeared in print in 1919. But humans were combining biological processes with technology to create medicines and foods long before anybody invented a word for it. Humans began growing crops and domesticating livestock around 8000 B.C.They began using yeast to ferment beer and leaven bread between 4000 B.C. and 2000 B.C. Mouldy soybean curds became the world’s first antibiotic when the Chinese used them to treat boils in 500 B.C.

2001 Complete human genome sequence published.

2000 109 million acres of biotech crops grown in 13 countries.
