Many elements occur naturally in low concentrations and may be essential for plant growth such as copper, zinc, iron or manganese. The high concentration of metals in edible mushrooms collected in nature is a source of chronic poisoning known for some time. Thus, the mushrooms may promote the spread of hazardous metals such as cadmium, lead and mercury from the environment in animal and human food chain. The use of manure, as a substrate for growth of cultivated mushrooms may promote the accumulation of these elements. The use of plant protection products (pesticides) for mushroom cultivation also contributes to the distribution of metals such as arsenic, copper, mercury, zinc and iron. This article summarizes the results of some scientific papers about possible chemical hazards from the consumption of mushrooms to be cultivated and spontaneous growth.

Today are cultivated more than 20 species of fungi, including Agaricus bisporus, using different types of matrices, including at least 200 types of waste. Agaricus bisporus is the most widely cultivated mushroom in the world and it is the species that requires a more complex substrates for growth. The mushroom Agaricus bisporus as provide a low energy intake and macronutrient, maybe considered a source of minerals and the consumption per capita per annum in someareas of the world, reaching 10 kg. The entire production cycle of Agaricus bisporus, from the preparation of the compost to the harvesting, takes about 10-12 weeks and includes the use for the growth substrate of chicken and/or horse manure. This article summarizes the stages of the cultivation of Agaricus bisporus, nutritional value and some possible health risks.

Cultivation of Agaricus bisporus mushrooms requires the use of substrates that are potentially dangerous from the microbiological point of view, such as chicken and horse manure. Microorganisms can pose risks to consumers and workers, and generate lower profits. Packaging of fresh mushrooms with impermeable films is used to extend their shelf life but creates anaerobic and humidity conditions that could favour the growth of microorganisms such as Listeria monocytogenes and Clostridium botulinum. This paper examines some alternatives for packaging fresh mushrooms and the resulting potential microbiological hazards.
