Cross-species transmission is the most significant cause of disease emergence in humans and other species. [citation needed] Wildlife zoonotic diseases of microbial origin are also the most common group of human emerging diseases, and CST between wildlife and livestock has appreciable economic impacts in agriculture by reducing livestock productivity and imposing export restrictions.

Cross‐contamination led to the first laboratory‐acquired human cowpox virus infection in the US in a laboratory worker conducting research on non-orthopoxvirus. [49] 2011 Dengue: Australia A scientist at a research laboratory in Australia got infected with Dengue through a mosquito bite in the laboratory. [50] 2012 Anthrax United Kingdom
An "incident" of chemical food contamination may be defined as an episodic occurrence of adverse health effects in humans (or animals that might be consumed by humans) following high exposure to particular chemicals, or instances where episodically high concentrations of chemical hazards were detected in the food chain and traced back to a particular event.
Whole Foods may end up cross-contaminating other stores with the labeling system, drawing even more attention to the company's large selection of health-conscious -- and high-margin -- products.
One significant cell-line cross contaminant is the immortal HeLa cell line. HeLa contamination was first noted in the early 1960s in non-human culture in the USA. Intraspecies contamination was discovered in nineteen cell lines in the seventies. In 1974, five human cell lines from the Soviet Union were found to be HeLa.
Any items which may cross-contaminate each other must be packaged separately. The containers should be closed and secured to prevent the mixture of evidence during transportation. Each container should have the collecting person's initials, the date and time it was collected; a complete description of the evidence and where it was found; and ...
The degree of gluten cross contamination tolerated by people with NCGS is not clear but there is some evidence that they can present with symptoms even after consumption of small amounts. [6] Sporadic accidental contaminations with gluten can reactivate movement disorders. [37]
Genetic pollution is a term for uncontrolled [1] [2] gene flow into wild populations. It is defined as "the dispersal of contaminated altered genes from genetically engineered organisms to natural organisms, esp. by cross-pollination", [3] but has come to be used in some broader ways.
