"Australian guidelines allow the use of growth hormones to increase the weight of cattle. The hormones most commonly used as growth promoters – oestrogen, progesterone and testosterone – also occur naturally in a wide range of foods.
However, the difference in hormone levels between hormone-fed and hormone-free beef is small. A single consumer would need to eat more than 77 kilograms of beef from a hormone-treated animal in one sitting to get the same level of oestrogen hormone found in one egg.
Hormone levels are regulated nationally to ensure that they are safe for consumers and not harmful to animals. However, if you prefer it, hormone-free beef is widely available from supermarkets and butchers."
