product tampering
Deliberate contamination of consumer products that endangers life or health
Product tampering is an international criminal-law term for the intentional and unlawful act of manipulating, contaminating or adulterating a consumer product so that it poses a danger to human life or health. The concept does not cover ordinary product modifications or quality defects, but specifically denotes criminal interference — for example the addition of toxic or harmful substances to a product that is sold or distributed to consumers. In US federal criminal law, which represents the most developed legislation in this area, it is typically required that the perpetrator acted with reckless disregard for the risk of death or serious bodily injury. It is therefore not sufficient that a product has been altered; the act must be committed intentionally and with an awareness of the serious danger it creates for other people.
The concept gained international attention and legal-historical significance in connection with the Tylenol murders in Chicago in 1982, where unknown perpetrators added cyanide to capsules of a painkiller that were subsequently sold in retail stores. Seven people died as a result of the poisoning. The case is a paradigmatic example of product tampering in its most serious form: deliberate criminal contamination of a mass consumer product with fatal consequences.
After the Tylenol case, the United States enacted a series of legislative changes that specifically criminalised product tampering at the federal level and tightened packaging-safety requirements in the pharmaceutical industry. These measures had global influence and led to the introduction of the sealed and tamper-evident packaging that is today standard for medicines and foodstuffs worldwide.
In legal and criminological terms, product tampering differs from ordinary sabotage or vandalism through its indirect character: the perpetrator strikes victims who are unknown and random, by means of a product they purchase and use in good faith. This makes the offence particularly difficult to investigate and prevent and places it in a distinct category of mass-harm crime.
