I read that the red berries from honeysuckle here in MO are poisonous.
I don’t remember the red berries from honeysuckle. Did you mean holly? Anyway, Kittnmom, another poster, said they have a horticulturalist in the family. Let’s see what she has to say.
What Are the Dangers of Honeysuckle?

Honeysuckle plants are members of the Caprifoliaceae family of plants, which consist of evergreen to semi-evergreen shrubs and vines. They are often cultivated in home landscapes as ornamental vines and are prized for their rapid growth and fragrant, attractive blooms. However, many varieties of honeysuckle are mildly poisonous, and if not properly maintained, most honeysuckle species can invade your landscape.
POISONOUS
If the berries of honeysuckle plants are ingested in large quantities, they can cause illness. Toxicity varies depending on the species, ranging from non-poisonous to mildly toxic. Symptoms of mild poisoning by honeysuckle berries include vomiting, diarrhea, sweats, dilated pupils and increased heartbeat. If ingested in large quantities, respiratory failure, convulsions and coma may occur. However, the nectar from the flowers of a honeysuckle plant can be ingested without harm, according to the North Carolina State University Cooperative Extension.
