Sir: I was not surprised to read your news on the severe impact the poor UK harvest has had on Weetabix production (‘Poor quality wheat crop halts Weetabix Minis production,’ 20 April). The company is likely to be one among many such cases this year.

Last year’s terrible growing conditions combined with the recent cold snap means global supply chains are facing challenges this year impacting the demand for and delivery of fruit and vegetables as well as meat, eggs and dairy products.

While the dedication of companies like Weetabix to stick to British-sourced products is admirable, the severity of the issues means all businesses should have alternative suppliers ready.

In a competitive market where consumers are seeking low prices, it’s vital the food supply chain is prepared. It needs to be ready for different eventualities and seek every opportunity to avoid unnecessary costs.

Collaborative relationships through the supply chain are key to minimising disruptions. If companies do not work together, they run the risk of losing competitive ground, even damaging reputations.
