Heavy metals in Chicken broth

Prepared broth and dry chicken stock powder are covered through source-specific metal measurements. Explore the distinctions between food measurements and separate microbiome studies.

Evidence review in progress. Compare values only when the product form, measurement basis, and metal species match.

Reported measurements

The population contamination profile on this page is unchanged. These notes do not set a typical value, an upper-tail value, or a certification limit.

Chicken stock powder, dry, as sold

Safwan and Amayreh measured chicken stock powders from the Jordanian market. This is dry stock powder, not prepared broth. Five chicken stock rows. The span of the central values is total chromium 0.281 to 0.451 mg/kg, cadmium 0.0042 to 0.0632 mg/kg, and lead ND to 0.645 mg/kg. One row prints the same ± 0.342 dispersion on several metals, copied as printed on the source note. The powder was later oven dried before ashing. Brand names are omitted. Mushroom soup and instant noodles in the same paper are not used. Chromium is total chromium.

Arsenic, mercury, nickel, aluminum, and tin are not in this chicken-stock span. Data gap for those metals. ND is not a measured zero.

Chicken broth, lead, cadmium, and why total chromium is a different question

Broth panels that report total chromium cannot be read as hexavalent chromium. The gut chromium experiment below used potassium dichromate by gavage. Lead and cadmium evidence is a human tooth-lead cohort and a mouse drinking-water study. A broth or bouillon supplier should report the chromium species the method actually measured, and should not attach a hexavalent-chromium microbiome result to a total-chromium cell.

Sitarik et al. 2020 measured tooth lead and stool microbiota at 1 month and 6 months in 146 maternal-child pairs in the Detroit-area WHEALS cohort. In utero tooth lead was associated with fungal community composition at 1 month. Lead was not associated with overall bacterial community structure. Taxon-level bacterial shifts were higher Collinsella at 1 month, higher Bilophila at 6 months, and lower Bacteroides. The direction is lead exposure toward microbiota composition. Tooth lead is a biomarker, not a concentration in this ingredient.

Zhang et al. 2015, per WikiBiome source summary, DOI 10.1021/acs.chemrestox.5b00237, gave mice 10 mg/L cadmium in drinking water for 10 weeks. Firmicutes and gamma-proteobacteria decreased in feces after 4 weeks, and Firmicutes decreased in cecum contents after 10 weeks. The direction is cadmium toward gut microbiota, alongside hepatic energy-metabolism changes in the same animals. The summary does not name a food.

Mu et al. 2023 gavaged mice with potassium dichromate at 75 mg/kg for 29 days (n = 60 across three groups). Hexavalent chromium lowered Chao1 diversity from 170.75 ± 15.79 to 87.00 ± 9.55 (p = 0.00029) and Shannon diversity from 4.64 ± 0.68 to 2.64 ± 0.64 (p = 0.0055). Escherichia_Shigella rose from 10.71 percent to 57.75 percent. Seaweed polysaccharide at 200 mg/kg partly reversed the shift. The direction is hexavalent chromium toward gut microbiota. The dose is a gavage dose. It is not a total-chromium concentration in food.

What remains uncertain

The dichromate dose is 75 mg/kg by gavage for 29 days, which is not a broth concentration and not total chromium. No study cited here fed chicken broth or sequenced broth microbiota. Collagen and fat in broth are not factors in these three papers.
