Determination of Heavy Metal Contamination in Premium and Supermarket Brands of Extruded Feline and Canine Food in the South African Market.
Article in Veterinary medicine and science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The recent increase in pet food recalls due to contamination and the increased risk of disease has highlighted the need for the screening of canine and feline pelleted food. Heavy metals, an often-overlooked contaminant, has been highlighted for its role in the development of companion animal disease. Therefore, it is imperative that heavy metal content in these commercially available pet foods is investigated. In this study, premium (n = 14) and supermarket brands (n = 17) of extruded cat and dog food were analyzed for the presence of As, Cd, Co, Cu, Fe, Pb, Hg, Ni and Zn using ICP-OES and Hg by HGAAS. Collectively, extruded dog food brands produced mean concentrations of 7.47 (As), 6.23 (Cd), 4.01 (Co), 16.72 (Ni), 3.99 (Pb), 0.47 (Hg), 35.59 (Cu), 529.53 (Fe) and 25.25 (Zn) mg/kg, whilst cat food brands contained 2.92 (As), 3.15 (Cd), 2.44 (Co), 4.26 (Ni), 7.24 (Pb), 0.16 (Hg), 38.08 (Cu), 389.14 (Fe) and 195.12 (Zn) mg/kg. Canine brands exceeded maximum tolerable limits (MTLs) more than feline with red meat proteins containing higher total heavy metal levels followed by poultry, fish and meat medley formulations. Furthermore, premium brands displayed higher levels of heavy metals exceeding MTLs than supermarket brands which were lower priced.
