I bought a Wood Fired Pizza from M&S last week and nearly choked on 1 1/2 inch wood splinter found in the pizza. Fortunately it wasn’t my 14 year old son who had swallowed it. Whilst there is a warning ( in small lettering) on the back of the packaging warning of SMALL chicken bones it doesn’t warn of large wood splinters . Take care or preferably DON’T BUY this product .
