The skull and crossbones has long been a standard symbol for [[poison]].

In 1829, [[New York State]] required the labeling of all containers of poisonous substances.<ref>{{cite book|url=https://books.google.com/books?id=N4N9bsxc2LYC&q=skull+and+crossbones+symbol+of+poison&pg=PA92|title=History of Drug Containers and Their Labels|first1=George B.|last1=Griffenhagen|first2=Mary|last2=Bogard|date=19 November 1999|publisher=Amer.

Previously a variety of motifs had been used, including the [[Denmark|Danish]] "+ + +" and drawings of [[skeleton]]s.<ref>{{cite magazine |title=Antique Poison Bottles |url=https://www.collectorsweekly.com/bottles/poison-bottles |magazine=Collectors Weekly |access-date=26 February 2022}}</ref>

In the 1870s poison manufacturers around the world began using bright [[Cobalt glass|cobalt]] bottles with a variety of raised bumps and designs (to enable easy recognition in the dark) to indicate poison,<ref>{{cite web |title=Poison bottle collection | series=Antiques Roadshow |url=https://www.bbc.co.uk/programmes/articles/2CJMhJnJW8lkGZ4S61fVvGf/poison-bottle-collection |publisher=BBC One |access-date=26 February 2022}}</ref> but by the 1880s the skull and cross bones had become ubiquitous, and the brightly coloured bottles lost their association.<ref name=Farmer>{{cite web |title=Evolution of the Poison Label: From Skull and Crossbones to Mr. Yuk |url=https://designresearch.sva.edu/research/evolution-of-the-poison-label-from-skull-and-crossbones-to-mr-yuk/ |first=Meg |last=Farmer |website=SVA.edu | date=March 2014 |access-date=26 February 2022}}</ref>

In the United States, due to concerns that the skull-and-crossbones symbol's association with [[pirates]] might encourage children to play with toxic materials, the [[Mr. Yuk]] symbol was created to denote poison. However, in 2001, the American Association of Poison Control Center voted to continue to require the skull and crossbones symbol.<ref name=Farmer />
