Research has shown that flax seeds are not only safe, but also highly beneficial.

Compounds in flax provide bioactivity of value to the health of animals and humans through their anti-inflammatory action, anti-oxidative capacity, and lipid modulating properties.
Dietary Flaxseed as a Strategy for Improving Human Health, (25 May 2019), also states:
"...no toxicity has ever been reported in clinical studies with dietary supplementation of flax seeds...” Plus, “..the human body can routinely detoxify up to 100 mg/day of cyanide.” A diet sufficient in protein, particularly sulfur-containing amino acids, further assists this process.
I suspect that this small amount of plant nitriles (organic cyanides) may be Nature’s ingenious way to kill off harmful bacteria, parasites, and viruses in gut microbiome of both humans and animals.
The blue flax flowers (other varieties are white, yellow, or pink) contain a mucilaginous seed called linseed or flax seed. Oil derived from this seed is a rich source of the essential fatty acid (EFAs), especially omega 3/linolenic acid (ALA).
It contains an average of 57 percent omega 3; 16 percent omega 6; and 18 percent of the non-essential omega 9. Flax seed oil is also naturally high in the antioxidant nutrients beta carotene (4,300 IU per Tbsp) and vitamin E (15 IU per Tbsp).

but also

beneficial.
