The verdict
Shirakiku brand, oyster sauce by Shirakiku scores 95/100 in PlainFoodSafe's ingredient screening. We compared its 8 labeled ingredients with FDA SAFFA regulatory records and CSPI Chemical Cuisine ratings; 1 ingredient is flagged for caution. This is a focused 8-component label led by Water, Sugar, Dextrin; compare those leading ingredients with the product's processing and nutrition fields before deciding whether it fits your goal. This is not a recall, allergy, medical, or dietary-safety determination.

What the Data Says About Shirakiku brand, oyster sauce
Shirakiku brand, oyster sauce by Shirakiku carries a composite safety score of 95/100, which we classify as "Safe" on our four-tier shelf-label framework.
Of the 8 ingredients parsed from this label, 5 are covered by a regulator or watchdog we screen against (Dextrin, Tapioca Starch, Caramel Coloring and 2 others), with 3 carrying an FDA Substances Added to Food (SAFFA) status and 4 a CSPI Chemical Cuisine rating. The remaining 3 ingredients appear in neither registry, so they neither raise nor lower the score. Each additive rated caution-or-worse penalizes the composite. Product data originates from the OpenFoodFacts collaborative catalog; safety annotations come from federal regulators and the Center for Science in the Public Interest. This score is a transparent derived index we compute from that public data, not an official FDA rating or endorsement; see the Methodology page for the exact weighting.
Our scan identified 1 flagged ingredient in this product, components that at least one official source has classified as requiring caution, targeted avoidance, or further evaluation. Flagged ingredients are the items most likely to surface in FDA inspection findings, state-level ingredient bans, or outbreak-related recall notices, so the per-ingredient breakdown below is the most useful lens for anyone screening this product for a specific dietary concern.
On the NOVA processing scale, Shirakiku brand, oyster sauce is classified as Group 4 (Ultra-processed). NOVA measures industrial processing intensity rather than ingredient-level safety, so it complements the SAFFA and CSPI ratings: a product can be clean on additive flags but heavily processed, or lightly processed but carry individually flagged ingredients. Combining both lenses gives a fuller picture than either alone.
How the three scores on this page were derived
Within the four-tier shelf-label framework this site publishes, the composite for this product falls in the highest band. That band is defined by a threshold on the derived score alone: it is where labels land once components carrying caution-or-worse registry ratings contribute little or nothing to the deduction. The band is a summary of what the screened registries return for the components that were parsed, so it inherits their coverage gaps — a component absent from both registries neither raises nor lowers the figure. The threshold and the weighting behind it are set out on the methodology page.
Nutri-Score assigned its lowest band to this label. The algorithm reserves that grade for nutrition panels where the values it penalises sit well above the components it credits. The two systems on this page measure genuinely different things: a product can hold this grade while carrying no additive flagged by the registries screened below, and a product graded well can carry several. Neither reading substitutes for the other, and the per-component table is where the additive picture is set out.
The declared list parsed into a small number of components. On a short list the registry screen covers close to everything the packaging declares, and any single matched component accounts for a correspondingly large share of the composite. Short lists also leave less room for parsing error, since there are fewer separators and qualifiers for the extraction to resolve.

Ingredient-list length is a descriptive property of the label, not a safety rating. A longer list is not automatically worse and a shorter one is not automatically better; the count is shown so the label can be placed against a comparable population. The comparison here runs against the 27,084 Condiments products we publish with a parsed label, not against the whole catalogue, because list length varies far more between categories than within one.
