I also added this onto the post yesterday.
This was an update on the original post.

I would seriously question the source of this post and the information in it.
Firstly they mention talking to a Dr. rather than a vet, despite the fact that the post seems to be about birds?
Surely if they are discussing animal safety they should be speaking with a vet.
The 'zinc in glue in non food packing' is one that has been flying (see what I did there - flying?) around bird forums for years*, and is another one of those urban myths that has never really been proven.
Some glues, on some packing may contain small amounts of things like borax or zinc but the amounts are almost undetectable in the very few studies that have ever been done and I could never find a single study that directly linked the death of a bird to having chewed cardboard and ingested excessive amounts of toxins from he glue.
Now disinfectant seems to have been thrown into the mix as a result of Covid, but the 'poisonous packing' rumours are not new, and have always remained unproven.
Obviously everyone needs to do what they feel is best for their pets, and if you have any concerns then do your own research, look for reputable sites and reliable scientific research done by actual scientists at established academic institutions.
Posts on social media can rarely be proven or backed up by real evidence and generally reply on spreading fear rather than useful information.
*Just to add that I owned birds for 17 years and was on multiple bird forums and chat groups, so this is not the first time I have heard this story.
