Coles supermarkets have implemented a temporary purchase limit on eggs.

Coles has introduced a nearly nationwide purchase limit on eggs due to shortages linked to bird flu disrupting the supermarket giant’s supply. Customers are now limited to two cartons each at all stores, except in Western Australia. This measure follows chicken culls triggered by bird flu outbreaks, leading to fewer eggs being laid.

“Due to a shortage of supply on eggs, we have introduced a temporary limit of two items per customer/transaction,” read signs across Coles supermarkets. “This will help maintain availability and support as many customers as possible. Thank you for your patience, we apologise for any inconvenience caused.”

Egg suppliers told 9News Melbourne that the situation was the worst they had seen in more than 20 years.
