Environmental Law Foundation v. Beech-Nut Nutrition Corp.
185 Cal. Rptr. 3d 189
Cal. Ct. App.2015Background
- Environmental Law Foundation (ELF) sued multiple food manufacturers and retailers under Proposition 65 alleging baby/toddler foods contain lead and require consumer warnings.
- Parties stipulated ELF proved the affirmative case and agreed the products contain lead; trial focused on defenses (safe harbor MADL, averaging, preemption, "naturally occurring").
- OEHHA regulations set MADL (reproductive) for lead at 0.5 micrograms/day; defendants relied on expert analyses comparing average consumer exposure to that regulatory safe harbor.
- Defendants’ experts (Petersen, Murray, Beck, Keen) averaged lead concentrations across many samples, used geometric means and multi-day consumption data (NET and NHANES), and modeled blood-lead impacts, concluding exposures fell below the MADL.
- ELF’s experts (Hu, Burton-Freeman) argued defendants improperly averaged across lots and over days, advocated analyzing individual high-dose occasions (using arithmetic mean and 85th percentile), and urged single-day exposure analysis.
- Trial court credited defendants’ experts, found exposures below the regulatory safe harbor, and entered judgment for defendants; the Court of Appeal affirmed.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Use of averaging across lots to determine "level in question" | Averaging masks high individual-unit exposures; OEHHA rejects averaging for food lots | Averaging across multiple samples is scientifically appropriate for estimating typical product concentration given within-unit variability | Court upheld averaging as permissible and supported by substantial evidence; OEHHA FSOR not a ban on averaging |
| Averaging exposure over time vs. single-day analysis | Must evaluate single-day (peak) exposures for reproductive teratogens; cannot compare multi-day averages to per-day MADL | Regulation contemplates pattern/duration; here products are infrequently consumed and averaging over relevant window is scientifically appropriate | Court accepted multi-day averaging given evidence of frequency, expert modeling, and absence of single-day harm showing |
| Adequacy/sufficiency of sampling and methodology | Petersen’s sample counts and statistical methods (geometric mean) were insufficient or unreliable for some products | Data derived from parties’ exchanged tests, aligned with FDA data; geometric mean appropriate for log-normal data | Court found data and methods were the type experts reasonably rely upon; appellant forfeited many methodological objections; substantial evidence supports methodology |
| Deference to OEHHA (agency interpretation) | Trial court should defer to OEHHA staff view (testimony) that one-day comparison required | No formal OEHHA policy adopted in writing; agency documents allow evaluation based on pattern/duration; court not bound by informal testimony | Court declined to defer to informal OEHHA testimony absent authoritative statement and found trial court’s interpretation reasonable |
