Should wild mushrooms be washed before drying?<\/h2>\r\n\r\n\r\n\r\n

Yes. Mushrooms picked in the woods must be washed thoroughly under running drinking water before being sliced and dried. If, for years, you have heard the absolute rule that \u201cyou must never wet mushrooms\u201d repeated time and again, the time has come to set the record straight: a wild mushroom is not a sterile product. To ensure safe, hygienic and top-quality drying, the correct use of water is not only permitted but is an absolute necessity.<\/p>\r\n\r\n\r\n\r\n

In culinary tradition, the advice not to wash mushrooms stems from the desire to preserve their firm texture for immediate use in a frying pan. However, when it comes to long-term preservation through dehydration, the rules change radically. Let\u2019s get straight to the crux of the matter: a mushroom intended for drying must enter the dehydrator completely free of soil, sand, debris and contaminants. And to achieve this, a brush and a knife are often not enough.<\/p>\r\n\r\n\r\n\r\n

Why wild mushrooms really do need to be washed<\/h2>\r\n\r\n\r\n\r\n

The reason why I strongly recommend washing them is very practical and leaves no room for romantic interpretations. A wild mushroom grows in a natural and entirely uncontrolled environment. As it develops, it may come into contact with soil, fine sand, decomposing plant matter, stagnant water or rainwater. But that\u2019s not all: the woodland is inhabited. Mushrooms are exposed to insects, snails, wild animals and their droppings. It is humanly impossible to know with certainty what every single porcini, chanterelle or honey mushroom has come into contact with whilst growing.<\/p>\r\n\r\n\r\n\r\n

In this context, washing is not a culinary quirk or a matter of personal preference: it is a basic hygiene measure prior to storage. The Codex Alimentarius and the most stringent food safety regulations are clear on this point, defining dried mushrooms as products that must be free from organic and mineral impurities. Leaving soil at the base of the stem, or grains of sand lodged between the gills or in the spongy flesh of boletes, means introducing a potentially dangerous soil-borne bacterial load into the dehydrator (and subsequently into your jars in the larder).<\/p>\r\n\r\n\r\n\r\n

The first fundamental rule: drying preserves food, it does not sterilise it<\/h2>\r\n\r\n\r\n\r\n

A common misconception, which I would like to correct straight away, is the belief that the heat from the dryer acts as a universal disinfectant. The dryer is not an autoclave and is no substitute for ensuring the hygiene of the raw materials.<\/p>\r\n\r\n\r\n\r\n

Drying works by reducing the free, available water within the food, thereby preventing the growth of mould, yeasts and most pathogenic bacteria. However, whilst removing the water stops the growth of microorganisms, it do not sterilise the product<\/strong>.<\/p>\r\n\r\n\r\n\r\n

Bacteria that may be present in the soil of a fresh mushroom (such as Listeria monocytogenes<\/em>, Salmonella spp.<\/em> e Bacillus cereus<\/em>) can easily survive in a dormant state in the dried mushroom for months on end. The risk will resurface as soon as the mushroom is rehydrated in the kitchen. Running water helps to drastically reduce this initial surface contamination. Furthermore, always bear in mind that drying:<\/p>\r\n\r\n\r\n\r\n
