Rosita Cod Liver Oil · lead test breakdown

Is Rosita Cod Liver Oil lead-safe?

Q: What is the FDA daily reference level for lead in food?

2.2 µg per day for children, 8.8 µg per day for adults (FDA Interim Reference Level). The IRL is an action threshold for ongoing federal monitoring, not a 'safe level' (no safe level of lead exposure exists for children per CDC). Dose math: lead in µg = (ppb × serving size in grams) ÷ 1000.

Lead Safe Mama tested one batch in 2024-12 and 850 ppb arsenic. Whether the next batch from the same shelf is similar is the actual question. Here is the breakdown.

Quick answer

One Lead Safe Mama ICP-MS test on a single batch of Rosita Cod Liver Oil was published in 2024-12. It came back positive for at least one heavy metal above her detection threshold. The single result is real for that batch. It does not tell you whether the next bag from the same shelf is similar. Brand consistency on heavy metals is a marketing claim, not a chemistry one.

Arsenic: 850 ppb × 150g = 127.50 µg per serving.

Single retail units of this product are available individually at standard retail. A current single-unit price is around $69.95. The "minimum order / sold by case" framing on Lead Safe Mama's budget page does not apply to this product.

The single test on record.

From Lead Safe Mama's published lab report. One batch, one ICP-MS panel, one moment in time. The number is real for that bag. It is not a brand verdict.

About the "minimum order" framing.

Lead Safe Mama's budget page justifies a $495 per-product community sponsorship rate in part by citing product-acquisition costs as high as $450, with a "minimum quantity of several units must be purchased (purchasing a single box or package online is not an option)" clause. For Rosita Cod Liver Oil, that does not apply. Single retail units are available individually at the price shown above. Her older May 2024 post pegged the high end at $150 — a 3× escalation in 12 months on the same site, both pages live.

What we'd recommend.

1. Don't make a brand decision off one batch. The 2024-12 Lead Safe Mama result describes one bag at one moment. Cereal grain absorbs metals unevenly across fields. Spices vary by source country. Same brand, different lot, can disagree by an order of magnitude.

2. If you want a sealed-sample retest, the Lead Lottery model is $100 per panel. Same lab Lead Safe Mama uses (since March 2025, Purity Labs in Lake Oswego, Oregon). Sealed retail unit shipped direct to the lab, factory seal opened only at the lab. 4 to 5× cheaper than her per-product Community Sponsorship rate.

3. Read the broader audit. Our food-testing audit of Lead Safe Mama catalogs 451 of her published tests, identifies which lab signed each report, and walks the math. /pages/contested-foods walks the cases where two samples of the same product produced very different numbers.

Nominate Rosita Cod Liver Oil for a sealed-sample retest.

If you chip in $100 to the Lead Lottery for this product, we buy a sealed retail unit, ship it sealed to Purity Labs, and publish the result side by side with the Lead Safe Mama number on record. Same lab. Real chain of custody. No anonymization.

Common questions.

Is Rosita Cod Liver Oil safe from lead?

Lead Safe Mama published a single ICP-MS result in 2024-12 reporting lead, cadmium, and/or arsenic above her detection thresholds. The result is real for that bag. It does not tell you what the next bag from the same shelf will read. Single-batch testing on packaged food is one snapshot, not a brand verdict. The dose math (ppb × serving size) is the only way to translate a ppb number into actual exposure.

Where can I buy Rosita Cod Liver Oil?

Single retail units are available individually. Most common SKU is around $69.95 at retail. Single-unit purchases are the standard option.

Has Rosita Cod Liver Oil been retested by another lab?

Not in our database. We have not yet received a sealed retail unit to retest at Purity Labs. If you have one, mail it. The Lead Lottery model funds one Purity Labs ICP-MS panel and one sealed retail unit for $100, which is roughly 5× cheaper than the equivalent Lead Safe Mama Community Sponsorship rate ($495 per product).

What is the FDA daily reference level for lead in food?

2.2 µg per day for children, 8.8 µg per day for adults (FDA Interim Reference Level). The IRL is an action threshold for ongoing federal monitoring, not a 'safe level' (no safe level of lead exposure exists for children per CDC). Dose math: lead in µg = (ppb × serving size in grams) ÷ 1000.

Why does the same product produce different test results on different days?

Two reasons. First, batch-to-batch variability is real in any food product. Same brand sources from different farms, different harvests, different countries, different factory runs. Cereal grain absorbs lead and cadmium unevenly across fields. Spices vary by source country. The same brand can change its ppb signature between lots, sometimes by an order of magnitude. Second, chain-of-custody differences matter. A sample opened and re-packaged in a home kitchen before it reaches the lab is not the same sample as one shipped sealed direct to the lab. Both are valid lab data, but they describe different things. Read the contested-foods cases.

What's in your cabinet right now.

Most lead exposure starts in the kitchen.

Vintage ceramic glazes. Brass cooking alloys made before 2014. Painted decoration on dishes. Imported spices. The kitchen is where the dose-per-day math happens, three meals a day for years even at low ppb. Most homes have something on this list within ten feet of where dinner gets made.

"Lead is bad" — the primary sources.

CDC: There is no safe blood lead level for children.
FDA: Closer to Zero action plan — interim reference level 2.2 µg/day for children, 8.8 µg/day for adults.
EPA: Action level 15 ppb in drinking water; the SDWA "lead-free" definition was tightened to 0.25% in 2014.
AAP: Prevention of Childhood Lead Toxicity (2016 policy statement).
CDC: Blood lead reference value — 3.5 µg/dL since 2021.

Find it. Deal with it. Don't let lead weigh you down.
