Overview
Jacobs and colleagues compiled the arsenic, lead, cadmium and mercury results that nine US baby food manufacturers post online (1362 products) and turned them into hazard quotients under low, LOD-equivalent (6 ppb) and high concentration scenarios. They did not measure any food themselves. The paper argues that “below LOD” labels are hard for caregivers to interpret when the LOD can be as high as 6 ppb.
Key numbers
- Brand-level reported lead ranged from below LOD to 16 ppb, with the lowest detected value 3.2 ppb (Table 1, p. 2; Results, p. 4).
- One manufacturer’s products ranged from below LOD to 108 ppb cadmium and below LOD to 48 ppb mercury (Table 1, p. 2).
- Under the high-concentration scenario, hazard quotients exceeded 1 for most intake combinations except arsenic in snack-size items (Figure 1, p. 4).
Methods (brief)
Results were taken from manufacturer websites, converted to mg/kg and multiplied by assumed intakes (21 g snacks, 113 g pouches, 200 g meals, one to five a day) and compared with OEHHA, US EPA and EFSA benchmarks. Laboratory methods and most LODs are not disclosed.
Evidence Fitness
Context only: the concentrations are secondary manufacturer data, pooled across pouches, snacks and meals with no product categories in the main text, and the product-level supplement was not available. It is a proxy for both root and non-root vegetable puree pages, so neither is linked.
