Major proposal for Coles and Woolworths meat aisles, girl falls off hotel balcony: Australian news live

A big change to meat packets across the country could be in the works and would likely give shoppers more confidence in whether their food is fit to eat or not.

A study from Monash University researchers and supported by Meat & Livestock Australia focused on use by dates placed on supermarket meat products, and has led to the proposal of a new innovative system that could interest the likes of Coles and Woolworths.

Instead of printing a date, small indicators are placed on the inside of the package and they change color in response to the rising pH levels caused by the growth of bacteria, indicating to the customer when a product is unfit to eat.

“Colour-changing indicators on the package are a way of giving consumers real time information that meat is still fit for consumption,” Dr Joanne Tanner, of the Department of Chemical and Biological Engineering, said.

“By contrast, a Best Before date merely represents a conservative estimate of how long the packaged meat will remain usable and is not a current gauge of freshness. It is based on a series of worst-case assumptions about its handling and refrigeration through the supply chain.”

“This means meat is often returned or disposed of when it is actually still fit for consumption.”
