(plaintiff fed their alpacas feed that they purchased from defendant that was contaminated at defendant’s plant resulting in death of several of plaintiff’s alpacas; compensatory damages awarded, but lower court declined to submit issue of punitive damages to jury; appellate court held that malice could be shown – defendant’s employees knew of and disregarded contamination risk; plaintiff need not prove that defendant knew that feed was contaminated and intended to mislead plaintiff; thus, jury should have been instructed on damage mitigation issue).
