Statement transcribed from the 2276 x 657 px Open Food Facts photograph uploaded 2025-08-20, allergens set in bold; its last sentence is completed from the 3024 x 4032 px back photograph of 2024-08-05, which carries the same statement from "palm fat" onwards beside "4 x 39.4 g ℮ = 157.6 g", the Fairtrade Cocoa mark and the contact blocks. The front photograph of the same day shows the yellow "4 BARS" flash, a "Mars = 39.4 g" portion icon, a reference-intake panel with saturates 3.0g (15%), sugars 24g (27%) and salt 0.27g (5%), "442 kcal" per 100 g, and a "Responsibly sourced 100% cocoa" roundel.

What the sources say about these ties

Mars, Incorporated owns: Wikipedia names Mars Inc. as the producer of the Mars bar since 1932.

Built from the ownership rows on the brand and company pages, each cited where it is recorded. Made in is the country of production on this product's record; the GS1 prefix of a barcode names the issuing organisation, not where the product was made.

About this product

Mars 4 bars is the British and Irish multipack of the Mars bar: four 39.4 g bars of milk chocolate (40%) with soft nougat (32%) and caramel centre (27%) in one outer wrapper, 157.6 g in all, sold under barcode 5000159551823.^[2]^[3] Its panel declares 1858 kJ / 442 kcal per 100 g and 732 kJ / 174 kcal per bar, with four portions to the pack.^[1] The back prints consumer contacts for Britain, through Mars Wrigley Confectionery UK, and for Ireland, through Mars Foods Ireland, and carries the Fairtrade Cocoa mark on a mass-balance basis.^[3]^[1] The front shows a yellow "4 BARS" flash and a "Responsibly sourced 100% cocoa" roundel.^[4] The brand belongs to Mars Inc.^[5]

Forrest Mars Sr. first made the bar in Slough in 1932, modelling it on his father's American Milky Way bar.^[5] This pack's statement lists whey permeate and fat-reduced cocoa powder and no lactose, milk protein or vanilla extract, which the earlier four-bar code 5000159484527 declared.^[2] The barcode's company prefix 5000159 belongs to the group's French confectionery company: GS1's list of GDSN member companies carries GLN 5000159000000 against MARS CHOCOLAT FRANCE, the former name of Mars Wrigley Confectionery France.^[6]

Coverage & research gaps (10)

Coverage measures the evidence recorded here. It does not rate the product.

Identity: 3 / 3 · Name, brand and classification recorded
Context: 1 / 2 · Evidence groups assigned to a researched label, edition or analysis
Label photographs: 0 / 1 · Researched contexts with an assigned photograph
British and Irish back label and front of the four-pack: nutrient evidence: 16 / 16 · Recorded nutrient rows linked to a source; not the number of nutrients that ought to exist

identity · unknown: The Mars bar family also lists 5000159484527, a 4 x 39.4 g pack photographed in 2019 and 2022 with lactose, milk protein and vanilla extract in its statement; whether this barcode replaced it is not stated by Mars.
markets · unknown: Search results name an ALDI Ireland groceries page "Caramel, Nougat & Milk Chocolate Bars Multipack 39.4g Mars" and a Rayburn Trading wholesale page under URLs ending in this barcode, and Tesco.com and Tesco.ie product 314095314 "Mars Chocolate Bars Multipack 4 X 39.4g 157.6G"; the ALDI page redirects to the aldi.ie home page, Rayburn returned an empty shell and Tesco answered 403, so none is a Markets row.
markets · unknown: Searched amazon.co.uk on 2026-09-25 for the barcode 5000159551823 (no results), for "Mars Bars 4 x 39.4g" (B01BND12YU, which prints the earlier code 5000159484527, and B06XXQGS1H) and for the brand "Mars"; no amazon.co.uk listing that prints this barcode was found.
markets · unknown: Searched amazon.ie on 2026-09-25 for the barcode 5000159551823 and for "Mars 4 x 39.4g" (both no results) and for the brand "Mars", which listed only other sizes; B01MTN9PBV was read directly and prints no barcode.
relationships · unknown: GS1's GDSN trading-partner list settles who holds the prefix but not how long it is, so 5000159 is recorded as a seven-digit prefix without a published allocation length.
identity · not_researched: The photographs read carry no origin statement, so country_of_origin is left empty.
evidence · stale: Evidence was observed over a year ago; check for newer labels. Historical evidence remains valid.
schema · schema_gap: Review and assign legacy facts to coherent observations.
ingredients · not_researched: Ingredient statement or sourced exemption not recorded.
