Brussels, May 30 - Cash-strapped Italian families may be spending more on food but they're opting for lower quality products that could pose health risks, farm group Coldiretti warned as it released new statistics Thursday. Researchers have found that six in 10 Italian families are choosing lower-cost food items that may be cheaper because they have not been properly processed, said Coldiretti. In fact, the number of warnings about contaminated food is on the rise, warned Coldiretti. So far this year, warnings have increased by 23% over the same period last year, it said. Coldiretti argues that domestically grown and produced food is the safest and called on the national government to develop a "strategic plan" to increase Italian food production while protecting agricultural land.
