The article highlights a significant increase in the prices of fish and shellfish in Spanish markets, with some products rising by as much as six euros per kilo in just one week. Despite this, prices of sirloin and suckling lamb have remained stable. The rising prices are attributed to a record high Consumer Price Index (CPI) of 5.6% in November, the highest in 29 years, driven by increases in fuel and food costs. Meanwhile, meat prices, including beef and lamb, have seen an average increase of three euros per kilo compared to last year. The economic uncertainty caused by the ongoing crisis is impacting customer purchasing behaviors, with some delaying their Christmas orders.
