Consumer Protection Goes to the Top of the Agenda
“In order to promote the interests of consumers and to ensure a high level of consumer protection, the community shall contribute to protecting the health, safey and economic interests of consumers, as well as promoting their right to information, education, and to organize themselves in order to safeguard their interests”
Article 153, Amsterdam Treaty (1999)

What is the FSAI?
• National agency responsible for the enforcement of food safety legislation in Ireland
• Statutory body established under the Food Safety Authority of Ireland Act, 1998
• Came into effect on 1st January 1999
• An independent and science-based agency• Report to the Minister for Health and Children
• Transparent and accountable.

FSAI mission
To protect consumers’ health and consumers’ interests by ensuring that food consumed, distributed, marketed or
produced in the state meets the highest standards of food safety and hygiene.

Definition of a Medicinal product (2004/27/EC)
• Any substance or combination of substances presented as having properties for treating or preventing disease in human beings; or
• Any substance or combination of substances which may be used in or administered to human beings either with a view to restoring, correcting or modifying physiological functions by exerting a pharmacological, immunological or metabolic action, or to making a medical diagnosis.
“In cases of doubt....... the provisions of this Directive shall apply”

Definition of Food (EC 178/2002)
Any substance or product, whether processed, partially processed or unprocessed,intended to be, or reasonably expected to be ingested by humans.
‘Food’ includes drink, chewing gum and any substance, including water,intentionally incorporated into the food during its manufacture, preparation or treatment.
‘Food’ shall not include:
(a) feed;(b) live animals unless they are prepared for placing on the market for human consumption;(c) plants prior to harvesting;(d) medicinal products; (e) cosmetics; (f) tobacco and tobacco products; (g) narcotic or psychotropic substances; (h) residues and contaminants.

EC 258/1997
Novel Foods
“..foods and food ingredients which have not hitherto been used for human consumption to a significant degree within the community..”
Including
“..foods and food ingredients consisting of or isolated from plants..”

Directive 2002/46/EC
Food Supplements
..foodstuffs the purpose of which is to supplement the normal diet and which are concentrated sources of nutrients or other substances with a nutritional or physiological effect, alone or in combination, marketed in dose form, namely forms such as capsules, pastilles, tablets, pills, and other similar forms, sachets of powder, ampoules of liquids, drop dispensing bottles, and other similar forms of liquids and powders designed to be taken in measured small unit quantities”

Council Directive 89/398/EEC
Foods for Particular Nutritional Uses (‘Parnuts’)
“foodstuffs which, owing to their special composition or manufacturing process are clearly distinguishable from foodstuffs for normal consumption, which are suitable for their claimed nutritional purposes and which are marketed in such a way as to indicate such suitability“
e.g. • infant formulae and follow-on formulae • dietary foods for special medical purposes • foods intended for use in energy restricted diets for weight
reduction • food intended to meet the expenditure of intense muscular
effort, especially for sportspeople • foods for persons suffering from carbohydrate-metabolism
disorders, (diabetes).

Product Comparison
•No difference in composition beyond natural variability from an accepted
traditional food, food ingredient or food additive: proceed to intake assessment
•Single or a few well-defined specific characteristics that are different from an
accepted traditional food, food ingredient or food additive: safety assessment
should focus on these characteristics
• The counterpart of the product under investigation is a traditional health
product (medicinal product or food supplement). In this situation, the relevance
to the new food application of the safety data available on the existing product
has to be assessed on a case-by-case basis. Further data to ensure the safety of
the food application of the product may be required.
•The product under investigation does not have any traditional food or health
product counterparts. Such a product requires a comprehensive safety
assessment, which is discussed below
© FSAI
Hazard Identification/characterization in Experimental Animals
•The extent of experimental investigation necessary depends on the adequacy of the
history of use and the product comparison database
•The modes of action of beneficial and adverse effects should be assessed
•Special studies may be necessary depending on the history of use and the mode of
action
•Safety studies should normally be performed on the characterized product of
commerce as consumed, at a range of doses including those that produce adverse
effects
•Studies (in vitro and in vivo) on specific biologically active sub-fractions can provide
valuable information for the design of safety studies and/or the interpretation of
relevant endpoints
•The influence of the matrix on the rate and extent of absorption of active
constituents should be studied
•Studies based on purer preparations may underestimate or overestimate the
potential for adverse effects of less pure preparations

Recent safety issues associated with botanical products
• Hepatotoxicity of kava-kava and comfrey• Carcinogenicity of Aristolochia spp• Recorded adverse interactions with licensed drugs (eg
St John’s Wort)
