E174 / Colours
Silver
Safety in brief
Better avoided
Recorded EatMatrix rating, not a new clinical review. The amount, your sensitivities and country rules still matter.
- Watch for
- No allergen or sensitivity is recorded for this ingredient here. Check the whole product label; this is not an allergen-free guarantee.
- Our advice
- Read the whole food label and consider how often you eat the product. A name or E number does not tell you the amount, and an ingredient rating cannot assess the entire food.
What it is
E174 is metallic silver used purely as a surface decoration on confectionery and chocolates, giving a shiny metallic finish. In the EU/UK it is authorised only for very limited decorative uses. EFSA's re-evaluations (2016 and a 2025 follow-up) could not fully confirm its safety because of insufficient data on particle size, including possible nanoscale particles, and how much silver ion is released and absorbed. Many countries outside the EU do not permit E174 in food at all.
Also appears on labels as: Silver, silver, Ag, Colloidal silver, Silver powder, Silver ions, Food grade silver, Metallic silver, Silver nitrate, Silver acetate, Silver chloride, E174.

Research & body effects
Health notes from our ingredient record
- Insufficient data on particle size distribution (including possible nanoscale fraction) in commercial silver used for food decoration.
- Uncertain absorption from silver ion release; EFSA has not been able to confirm safety with current data (2016 review; 2025 follow-up).
- No JECFA acceptable daily intake (ADI) has been established, and several countries do not permit its food use at all.

Country rules
Country checks for E174
Permission depends on the market, type of food, amount and conditions. A scientific opinion or an E-number alone does not establish a legal use. These checks are separate from the stored EatMatrix rating.
Compare all eight markets and their sources
| Market | What is checked |
|---|---|
| European Union | Regulation (EC) 1333/2008, Annex II Part B, version , contains the exact code E174: Silver. Listing alone does not allow every food use. Part E food categories, limits, specifications and applicable later acts still need a product-specific check. Source read: . |
| Great Britain | The FSA register record for E174 (Silver) lists “Authorised” in England, Scotland and Wales. Register updated: 01 April 2025; record checked: . Food-specific conditions and specifications still need a separate legal check. |
| United States | Complete current-use review pending. Any scoped provision in the label guide above applies only to the stated use. FDA explains the applicable food-additive and GRAS framework. |
| Northern Ireland | Review pending. Check the applicable EU rules and territory arrangements; the GB register alone does not establish this status. FSA guidance is a starting source, not a verified permission for this entry. |
| Canada | Named food-use records located. Health Canada lists the preparations below for specified foods and purposes. This is conditional permission for those uses, not approval of every product or a personal safety verdict. Only the named records and conditions below were located.

Good Manufacturing Practice (GMP) is a condition of use, not an unlimited amount or a recommended intake. Food and Drug Regulations B.16.003 requires the listed source, purpose, amount and other conditions to match.

EatMatrix reading: match the exact preparation and food first. A manufacturing limit is not an acceptable daily intake (ADI). A label without the amount cannot establish exposure, and an unlisted name here does not establish a ban. |
