This paper assessed mycotoxins and toxic metals in 90 commercial pureed (wet) baby food products from three regional markets in Ghana. The products studied are commercially produced pureed baby foods in jars or pouches, not infant formula powder. This distinction is critical for routing: this source belongs on pureed-baby-food product pages, not on infant formula powder pages.
Toxic metals measured include lead, cadmium, arsenic, mercury, copper, and chromium by atomic absorption spectrometry (FIAS-AAS, GF-AAS, FAAS). The results showed trace amounts of lead, cadmium, mercury, and arsenic in the pureed products. Health risk assessment indicated no adverse non-cancer or cancer health effects: estimated daily intake was below provisional tolerable daily intake for all metals, and incremental lifetime cancer risk values were below 10^-6.
Key numbers
The paper reports that trace amounts of lead, cadmium, mercury, arsenic, and copper were detected. Specific quantitative values are not provided in the abstract; the paper states EDI < PTDI for all metals measured.
| Analyte | Finding | Health risk assessment |
|---|---|---|
| Lead | Trace amounts detected | EDI below PTDI; no adverse effect |
| Cadmium | Trace amounts detected | EDI below PTDI; no adverse effect |
| Total arsenic | Trace amounts detected | EDI below PTDI; ILCR < 10^-6 |
| Total mercury | Trace amounts detected | EDI below PTDI; no adverse effect |
| Chromium | Measured | Not flagged |
Mycotoxin findings: aflatoxins 0.315-11.446 µg/kg; Ochratoxin A 1.991-2.510 µg/kg; fungal loads 3.2-4.52 log CFU/g. Mycotoxin contamination was more prominent than heavy metal contamination in this dataset.
Methods (brief)
Random sampling from markets in Kumasi, Accra, and Ho (Ghana). Atomic absorption spectrometry for metals (FIAS-AAS for arsenic via hydride generation, GF-AAS, FAAS, and cold vapor for mercury). HPLC-FLD for mycotoxins. Recoveries 80-120% for mycotoxins. Sample type: 5 product types (pureed commercial baby foods in various flavors), 6 replicates per product type per region.
Evidence fitness
This source is relevant to pureed baby food product pages (fruit purees, non-root vegetable purees) in the Ghana regional market context. It is not evidence for infant formula stage 1 concentration data because the matrix is pureed baby food, not formula powder. The lack of specific quantitative metal values in the abstract limits its utility for contamination-profile rows; the full paper tables would be needed.
The B-tier rating reflects developing-country analytical context with limited CRM performance reporting in the abstract; full methods are described in the paper.
Limitations
Products are pureed (wet) commercial baby foods, not infant formula powder. The paper does not state stage designation. Sample size is 90 total products across 5 product types. Specific metal concentration values are not extracted here; the abstract reports only “trace amounts” without ranges. This study also covers mycotoxins (the primary focus of the investigation), not exclusively heavy metals.
