China imported pet foods: preprint evidence

Du et al.’s 2024 preprint reports 79 imported dry cat/dog foods in a China retail sample of 93 products manufactured in 2021–2022. Source-defined positive-only means were Pb 3.63, Cd 0.147, total Cr 3.87, total Hg 0.011 and total As 0.23 mg/kg (Table 5). Cadmium values conflict with the stated quantitation limit, and moisture basis and nutritional completeness are not documented. This is broad product context for the same cohort later published in 2025; it must not count as a second study.

Dry dog-food formulation comparison

Kim et al.(2018) measured 51 maintenance or all-life-stage dry dog foods,17 each with fish, poultry or red-meat primary proteins. Table 1 reports medians and ranges per 1,000 kcal of metabolizable energy. Fish-formulation total arsenic was median 0.343(range 0.025–1.104)mg/Mcal; red-meat lead was median 0.091(range 0.032–1.621)mg/Mcal. Results concern one lot per formulation. Individual energy densities are unavailable, so these group summaries cannot be converted to mg/kg. Protein-group associations do not prove contamination of the raw ingredients.

How standards math uses this page

HMT&C certification thresholds for this row are developed under the certification program at heavymetalcertified.com, not on this page. The row-standard for this row is an aggregate computed from the contributing source pool in the row’s native finished-product basis; it is not a per-source decoration of any single value cited on this page. This public page reports literature evidence only.

Historical recalls and enforcement

Public regulatory events for this row, such as recalls and import alerts, will be listed here as they are catalogued.

Methodology

This page reports what the cited sources say about heavy-metal concentrations in complete & balanced dry (kibble). Speciation is non-substitutable (iAs vs tAs, MeHg vs tHg, Cr-VI vs total Cr). Basis is preserved (finished-product as sold unless the source specifies otherwise; see each row for the basis label). Non-detect handling follows each source’s reporting convention. Pooling is avoided across LOD/LOQ, period, geography, and analytical-basis differences. HMT&C certification thresholds for products in this row are developed under the certification program at heavymetalcertified.com, not on this page; this public page reports literature evidence only.

The applicable regulatory jurisdictions for this row are: FDA CVM, AAFCO, EU Directive 2002/32.
