Scoring methodology · Eggs
Every egg product is evaluated against 9 rules, worth a total of 220 points. Your score is the percentage of points the product earns on what we actually know about it.
Quality score
Each rule contributes points up to a known maximum. We sum them, divide by the total possible, and that's the headline number on the product.
Unknowns
If we couldn't verify an attribute, that rule earns zero. Brands aren't rewarded for non-disclosure, and we don't fill the gap with a guess.
clean_ingredients
No harmful contaminants flagged on this product. Intrinsic egg fatty acids (palmitic, oleic, DHA, EPA, etc.) are not penalized; PFAS contaminants always are. Severity- and amount-weighted against food guidelines (MADL).
feed_quality
What the hens eat. Pasture-forage (insects + greens, no grain) earns the most. Any corn or soy supplementation — even on organic operations — drops to zero.
living_conditions
How the hens are housed. Pasture-raised earns the most (continuous outdoor access, low density). Caged operations earn zero.
quality_certifications
Organic certification carries the most weight. Brands disclosing organic feed (without full cert), regenerative practices, or glyphosate testing earn smaller credits on top. Unlike v1, brands without an explicit Non-organic cert can still earn these credits.
packaging
Carton material, detected by substring matching across the raw packaging string. Worst material in compound values wins (e.g. "cardboard + polystyrene" is scored at the polystyrene tier). Paperboard / cardboard / pulp cartons score near the top; plastic, PET, and polystyrene earn less due to leaching and microplastic risk. Generic "carton" with no material signal is assumed paperboard.
antibiotic_use
Whether antibiotics are used in the flock. Never-use operations earn the most; routine prophylactic use earns zero.
pesticide_risk
Expected pesticide load based on feed sourcing. Low risk (organic / tested) earns the most; commodity-feed operations score zero.
additives
Post-lay treatments. None or natural marigold colorant score the most; chemical washes and synthetic colorants drop the score.
lab_indexed
Whether a full lab report has been indexed for this product. Smaller weight than other categories since eggs scoring is dominated by farm-practice signals.
Scoring is a function applied to evidence. If you think a rule fired on the wrong evidence, the per-product breakdown shows the source for every contribution — each one is challengeable. The methodology itself is version-controlled and evolves in public.
