These are the current pressures on food prices:
Mass resignations and early retirements post and during covid reduced workforce
Brexit (UK) reduced labour availability
Increased demand post Covid pushed up worldwide labour and fuel demand reducing availability and increasing cost of both
War in Ukraine is increasing commodity prices of basic foodstuffs like wheat
Food price inflation is already the highest in decades and more is forecast while retailers are still pushing to be the cheapest
Just about every value engineering option out there has been done already from the last decades of supermarkets not accepting price increases
War in Ukraine is pushing up fuel prices
Potential threats between hostile nations could impact foods
All of this is MASSIVELY increasing risk of economically or ideologically motivated fraud or food contamination. There is far more testing out there than there was but it's hard to find something when you don't know what to look for. I'm convinced the next major scandal is probably already happening.
