Sus scrofa is one of the most successful environmental and agricultural pests in Australia. Commonly known as feral pigs, their numbers are said to range between 3.2 million and 30 million and they inhabit 45% of the country’s land mass. Farmers and scientists have been working on containment programs for several years, with limited success. These animals reproduce at an alarming rate, destroy livestock, spread weeds, and damage infrastructure. Common food sources for these voracious creatures are food at landfill dump sites and food waste that is being composted. Food waste can contain contaminated animal products (whether legally imported or otherwise) that may not be safe for feeding to domestic or feral livestock.
