La science
Penitrem A / roquefortine (mould); juglone (black walnut)Mouldy nuts can be colonised by Penicillium species that produce penitrem A and roquefortine, which inhibit inhibitory neurotransmitters in the brain and cause whole-body tremors and seizures. Black walnut hulls contain juglone, which is toxic to dogs (less so than to horses). Fat content also poses a pancreatitis risk.
