Hawaii is often seen as an idyllic holiday destination, a place of sun, sea and sand. However, following a 1,400 tonne treacle spill off the coast, warnings have been issued against swimming as the treacle may attract sharks.
A leak was found in a pipeline which is used to load treacle onto ships. As a result of the spill, a large brown sugary slick can be seen in Honolulu's harbour and nearby lagoon.
It has also had serious environmental consequences. The State Health Department commented, "the substance is polluting the water, causing fish to die and could lead to an increase in predator species such as sharks, barracuda and eels."
There is also a slight worry that the increase in sugar in the water could promote the growth of algae.
Although the pipe is now repaired, the environmental damage has been done. Health officials expect the slick to be visible for weeks until tides and currents flush it out.
