Food Safety Auditor: What EU Supplement Brands Should Expect

An email arrives from a retailer, a distributor or a public authority saying that a food safety auditor will review your supplement range. The first question is not “what will they ask?” but “which kind of auditor is this?” The phrase covers very different roles, and the answer changes what you prepare.

This article separates those roles, then walks through what the official EU sources say about audits, who is responsible for supplement safety, and which legislation a reviewer is likely to use as a reference. It is written for regulatory affairs managers and quality leads at brands that sell, or plan to sell, food supplements and herbal products in Europe.

Which food safety auditor are you dealing with?

In practice, a food safety auditor can be one of three people:

An inspector from a national competent authority, checking your business under official controls.
A European Commission auditor, who does not usually audit your company directly. The Commission’s audits look at whether national systems work.
A customer or certification-scheme auditor, who checks you against a private standard or a contract.

The official sources used for this article cover the first two. They do not describe private certification schemes, so check the scheme’s own documents if a customer or certification body is the one asking. The rest of this article concentrates on the public side, because that is where the legal obligations come from.

What Commission audits actually examine

The Commission carries out controls and oversight tasks to monitor how EU legislation on food and feed safety is implemented and enforced [3]. Within the Commission, a specific Directorate for Health and Food Audits and Analysis dedicates most of its resources to these controls [3].

Its main purpose is to ensure that national authorities in EU Member States fulfil their legal obligations, and that the same happens in non-EU countries exporting to the EU [3]. In general, the audits focus on official control systems rather than individual premises [3].

For a supplement brand, this has a practical meaning. The Commission is checking the authority that oversees you, not your factory floor. National inspectors, in turn, are expected to run a credible control system, so the way they look at your business reflects what the Commission expects of them.

A few details are worth knowing:

The audit team is typically composed of two auditors, often with a national expert from an EU country present [3].
The team gathers information beforehand by sending an audit plan and a pre-audit questionnaire [3].
Audit reports are, with few exceptions, publicly available [3].
Overview reports summarise the situation in a sector across Europe and are presented to the EU Member States in the Standing Committee on Plants, Animals, Food and Feed [3].

The public reports are useful reading. They show which weaknesses authorities are being asked to address, which is a fair hint at where inspectors may look harder.

Where responsibility for supplement safety sits

If you remember one point from this article, make it this one. Under the EU General Food Law Regulation (EC) No 178/2002, food supplements are considered foodstuffs, and responsibility for their safety lies with the food business operator placing the product on the market [2].

The same source widens the circle: because food supplements are considered food, it is the responsibility of the manufacturer, importer, supplier or distributor to ensure that a supplement placed on the market is safe [2].

For a brand outside the EU, the wording on importers and distributors deserves attention. You cannot treat safety as something that stays with the manufacturer. If you export to Europe, ask your importer and distributor what documentation they hold and what they would hand over to an inspector. Agree this in writing before any audit is announced.

The legislation a reviewer is likely to reference

There is no single “supplement audit checklist” in the sources, so the safest approach is to organise your product file by legislation. The table below maps common review topics to the rules the official sources name.

Topic	What to be able to show	Source
Vitamins and minerals	Each one appears in Annex I of Directive 2002/46/EC, and its source appears in Annex II	[1]
Additives	Each additive is specifically authorised for this food category under Regulation (EC) No 1333/2008	[2]
Novel ingredients	Where a substance has no history of safe use in the EU before 15 May 1997, it is assessed under Regulation (EC) No 2015/2283	[2]
Other substances	None of your ingredients appears on the list in Annex III of Regulation (EC) No 1925/2006 as prohibited, restricted or under scrutiny	[2][4]

Vitamins and minerals

Directive 2002/46/EC lays down a harmonised list of vitamins and minerals that may be added for nutritional purposes in food supplements, in Annex I, and a list of permitted sources in Annex II [1]. The trade of products containing vitamins and minerals not listed in Annex II has been prohibited from the 1st of August 2005 [1].

A reviewer comparing your formula against these annexes is doing a simple check, so make it easy: list each vitamin and mineral next to the form you use and the annex entry that covers it.

Additives

Supplements may contain additives such as sweeteners, colours and coating agents, but in the EU only food additives specifically authorised for this food category under Regulation (EC) No 1333/2008 can be added [2]. Coating agents for tablets and sweeteners in chewables are easy to overlook when a recipe is reformulated, so recheck them whenever the formula changes.

Botanicals and other substances

Ingredients other than vitamins and minerals, such as botanicals, may be authorised under other specific legislation depending on the nature of the substance, for example novel foods, fortification rules or foods for specific groups [2]. This is where herbal brands carry the most risk, because the route depends on the ingredient.

Annex III of Regulation (EC) No 1925/2006 is a list of substances other than vitamins or minerals whose use in foods is prohibited, restricted or under scrutiny [4]. The Commission may start the Article 8 procedure for a substance on its own initiative or at the request of a Member State [4]. The sources name several substances that have gone through this process or the related safety work:

Ephedra species and Yohimbe [4]
Hydroxyanthracene derivatives [4]
Green tea catechins, particularly EGCG [4]
Monacolins from red yeast rice [4]
Alpha-lipoic acid [2][4]

EFSA carries out safety assessments of these ingredients because safety concerns were raised either by the Commission or by Member States [2]. If your range includes any of them, expect questions, and keep the current regulatory position on file rather than relying on memory.

Notification and why national practice differs

Under Article 10 of the Directive, EU countries may request, for monitoring purposes, notification to their competent authority when a food supplement is placed on the market in their territory [1]. That is a power Member States may use, so it does not apply identically everywhere.

A Commission news item published on 08 July 2015 reports that the Food and Veterinary Office visited five Member States in 2013 and 2014 to obtain an overview of the controls carried out on food supplements [5]. In most Member States, producers or traders have to notify the national authorities about the products marketed, but the procedures for assessing those notifications differ considerably within the EU [5]. Member States pointed out that the lack of harmonised lists of approved plant and herbal extracts, and of maximum levels for vitamins and minerals, means that safety criteria are not transparent to traders, inspectors and consumers [5].

The Commission’s current supplements page confirms part of this. It says the Commission has not yet presented a proposal on maximum and minimum amounts of vitamins and minerals, citing the complex nature of the issue and the divergent views expressed [1].

Because older material may no longer reflect today’s practice, treat that news item as background and confirm the current rules with the authority in each country where you sell. Requirements vary by member state, so a file that satisfied one inspector may need adjusting for the next.

Why supplements attract scrutiny

The same news item notes a growing trade in food supplements in the EU, especially via the internet, and an increasing number of alert notifications in the EU Rapid Alert System for Food, which it says demonstrates that these products can be a real risk to food safety [5]. It also states the purpose of these products: to supplement the normal diet, but not to treat or cure a disease [5].

For you, that is a reminder of where attention tends to fall. Online sales, ingredient safety and claims that drift towards treatment are all areas where a reviewer may want to see careful controls and careful wording.

How to prepare before the auditor arrives

You cannot predict every question, but you can make your file easy to read. The steps below follow from the sources and from ordinary good practice, so adapt them to your range and your markets.

Identify the auditor and the standard. Ask whether the review is an official inspection or a customer or scheme audit, and request the scope in writing.
Build an ingredient register. For each ingredient, record the legal route it relies on: the vitamin and mineral annexes, the additives rules, novel food status or another framework.
Check the watch-list substances. Compare your formulas against the substances named above and note the current position for each one you use.
Map responsibilities in the supply chain. Write down who is the manufacturer, importer, supplier and distributor for every product, since the safety duty reaches all of them.
Check notification status country by country. Where a Member State asks for notification, keep proof of it with the product file.
Read recent public reports. Audit and overview reports show where authorities have been asked to improve their controls.
Do a mock review. Ask someone outside your product team to open the file cold and find each document. Gaps usually show up within minutes.

If you sell herbal products, a qualified EU regulatory expert can confirm the legal status of each botanical in the markets you target, and an accredited laboratory can test the product itself. Start with the register in step two, because every other step builds on it.
