526 F.Supp.3d 652
N.D. Cal.2021Background
- WellPet markets three “Wellness” premium dry dog foods with statements like “Natural,” “Uncompromising Nutrition,” and “Complete Health.” Plaintiff Daniel Zeiger alleges the products contained arsenic, lead, and BPA that WellPet did not disclose.
- Zeiger purchased Wellness products regularly from 2014–2017 and stopped after learning of the alleged contaminants; he seeks class relief under California consumer-protection statutes and warranty theories.
- Parties submitted cross-motions: WellPet moved for summary judgment and Daubert challenges to several plaintiff experts; Zeiger moved for class certification (23(b)(3) damages class and 23(b)(2) injunctive class).
- Court admitted plaintiff expert Dr. Pusillo’s opinions on arsenic/lead (bioaccumulation) but excluded his BPA opinion; it excluded portions of Dr. Callan’s and WellPet’s Kean’s testimony as impermissible expert/legal assertions.
- Court denied summary judgment on most claims (finding genuine dispute about arsenic/lead risk) but granted summary judgment as to BPA safety, as plaintiff offered no admissible expert dispute on BPA.
- Court denied certification of a Rule 23(b)(3) damages class for now because plaintiff’s conjoint-based damages model was not admissible (would yield de facto full refunds); granted a Rule 23(b)(2) class for injunctive relief and gave plaintiff leave to renew 23(b)(3) certification with a new damages model.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Safety of arsenic & lead | Small amounts bioaccumulate; even trace levels can be unsafe over time (Pusillo) | Levels are naturally occurring, ubiquitous, and not shown to harm dogs at alleged concentrations | Genuine dispute of material fact exists; summary judgment denied on these safety claims |
| Safety of BPA | BPA detected in many samples; risk alleged | No admissible expert linking detected BPA levels to health risk | Summary judgment for WellPet: alleged BPA levels do not present a health risk (Pusillo’s BPA opinion excluded) |
| Admissibility of Pusillo’s opinions | Qualified animal-nutrition expert on bioaccumulation and testing | Too speculative or outside his specialty for some opinions (esp. BPA) | Pusillo admissible on arsenic/lead and testing/prevention (except assertion products contained metals "for years"); BPA opinion excluded |
| Admissibility of Callan’s opinions | Lab detected quantifiable BPA in many samples; also opined on likely systemic QC issues | Not qualified to opine on manufacturing/supply-source issues; methodology unsupported | Lab results admissible; Callan’s opinions about sources and systemic QC excluded |
| Misleading marketing statements & omissions | Wellness statements + nondisclosure of contaminants convey healthy/natural/high-quality and are materially misleading | Statements are puffery/clarified by surrounding text; substances ubiquitous so no duty to disclose | Whether statements/omissions mislead reasonable consumers is factual; summary judgment denied on statements and omissions (omissions claims survive) |
| Reliance & injury | Zeiger relied on packaging/natural claims and would have purchased differently if informed | Zeiger knew metals are ubiquitous; lacks recall of specifics | Genuine disputes of fact on reliance; summary judgment denied on reliance |
| Damages model & class predominance (23(b)(3)) | Conjoint survey measures price premium for statements/omissions to calculate restitution | Model yields full-refund results and is untethered to liability theory; thus inadmissible | 23(b)(3) certification denied without prejudice because damages model is not admissible; leave to renew with proper model |
| Injunctive relief standing (23(b)(2)) | Zeiger is "open to" repurchasing if labels are fixed, so faces future harm/uncertainty | Lacks concrete plan to repurchase; no standing | 23(b)(2) injunctive class certified; Davidson precedent supports standing to seek injunction |
| Negligent misrepresentation (economic loss) | Alleges negligent misrep leading to economic loss | Economic loss rule bars tort recovery for purely economic damages | Negligent misrepresentation claim dismissed under the economic loss rule |
