The bag reduction I would argue is a &quot;good&quot; thing, that being said, there have been reports about reusable bags causing nasty food poisoning.<p>The problem is a lot of reusable bags aren&#x27;t easy to clean (e.g. cannot be placed in a washing machine) and people reuse bags for both uncooked meats and fresh vegetables then just leave them for long periods with food bacteria on them.<p>Most of the general public doesn&#x27;t realise the risk, and unfortunately even if you do realise it, most re-usable bags aren&#x27;t cleanable anyway. All you can do is spray them with disinfecting spray every so often and hope for the best.
