Supermarket: has yours been tested for this toxic fungus?

Supermarket: has yours been tested for this toxic fungus?

When we go to the supermarket to buy food products, we take for granted that what we put in our cart is safe and checked. This trust also extends to mushrooms, prized foods that can hide deadly pitfalls if not properly verified.

In this article, we will delve into the control mechanisms that should guarantee the safety of mushrooms sold in large-scale retail, analyze the real risks, and provide concrete data on the Italian situation. Together we will discover if the checks carried out are sufficient to protect consumers and what precautions you should take when buying mushrooms at the supermarket.

 

Supermarkets and safety: regulatory framework and responsibilities

The food safety control system in Italy is complex and involves different actors, from producers to distributors, up to the surveillance authorities. Understanding this regulatory framework is essential to evaluate the reliability of the fungal products we find on supermarket shelves. In this section, we will examine the main regulations governing the marketing of mushrooms and the responsibilities of the different subjects involved in the supply chain.

European and National Regulations on the Sale of Mushrooms

The marketing of fresh epigeous mushrooms in Italy is regulated by a series of laws and decrees that establish precise safety requirements. Regulation EC No. 178/2002 establishes the general principles and requirements of food legislation, establishing the European Food Safety Authority (EFSA) and setting procedures in the field of food safety.

At the national level, the Ministerial Decree of November 29, 1996 "Regulations on the collection and marketing of fresh and preserved epigeous mushrooms" represents the main reference text. This decree establishes that mushrooms intended for sale must undergo an edibility control by mycologists registered with the national register. Mushrooms must be identified with the full scientific name (genus, species, author) and the commercial name, where provided.

Controls must be carried out on each batch of mushrooms before marketing. The mycologists in charge of the control must verify that the mushrooms belong to edible species, that they are in a good state of preservation, and that they do not present alterations that compromise their wholesomeness. Each controlled batch must be accompanied by a transport document certifying the control carried out and their edibility. This system, in theory, should guarantee that only mushrooms safe for human consumption reach the supermarkets.

The responsibilities of large-scale retail

Supermarkets and large-scale retail (GDO) have precise responsibilities regarding food safety: according to the "from farm to fork" principle established by European legislation, every operator in the food chain is responsible for the safety of the food they market. Supermarkets must therefore ensure that mushroom suppliers comply with all current regulations and that the products are accompanied by the necessary documentation certifying their safety.

Furthermore, supermarkets must implement self-control systems based on the HACCP system (Hazard Analysis and Critical Control Points), which involves the identification, evaluation, and control of significant hazards to food safety. This means that supermarkets should have specific procedures for the management and control of fresh mushrooms, including protocols for recognizing any non-conformities and for the withdrawal from the market of unsafe products.

The most dangerous poisonous mushrooms: how to recognize and avoid confusion

Confusion between edible and toxic species is one of the main causes of mushroom poisoning: also in supermarkets, although rarely, identification errors can occur with potentially serious consequences. In this section, we will analyze the most dangerous toxic species that could be confused with edible mushrooms, providing distinctive elements for their recognition and data on poisonings recorded in Italy.

Amanita phalloides: the most dangerous mushroom of All

The Amanita phalloides, commonly known as the "death cap", is responsible for the majority of deaths from mushroom poisoning in Europe. This mushroom contains several toxins, mainly amatoxins, which cause irreversible liver damage. The particularity of these toxins is that the symptoms of poisoning appear several hours after ingestion, when damage to internal organs is already underway, making timely intervention difficult.

The Amanita phalloides can be confused with edible species such as the Caesar's Mushroom (Amanita Caesarea) when they are still at the closed "egg" stage, or with some meadow mushrooms. The distinctive features of Amanita phalloides include: the cap color varying from olive green to yellowish-green, the white gills, the white ring, and the well-evident volva at the base of the stem. I t is essential to remember that the volva is a distinctive feature of Amanitas and must always be checked.

Cortinarius orellanus and speciosissimus: the dangerous "Cortinarius"

The Cortinarius orellanus and speciosissimus are mushrooms containing orellanine, a toxin that causes irreversible kidney failure. Poisoning from these mushrooms has a particularly long latency period, which can last up to 3 weeks, making it difficult to link the symptoms to mushroom consumption. These Cortinarius could be confused with edible mushrooms such as honey mushrooms (Armillaria mellea) or other orange-brown mushrooms.

The distinctive features of toxic Cortinarius include: the orange-brown color of the cap, the cinnamon-colored gills, the often slender stem and, above all, the presence of the cortina (a cobweb-like veil) between the cap edge and the stem in young mushrooms. The presence of the cortina is a fundamental characteristic for recognizing mushrooms belonging to this genus.

Actual controls in supermarkets: between theory and practice

Despite the existence of an apparently rigorous regulatory framework, in practice, controls on mushrooms in supermarkets can have gaps and critical issues. In this section, we will examine how controls really work, what the weak points of the system are, and what concrete risks consumers run when buying mushrooms in large-scale retail.

The official control system: NAS and ASL

Official controls on food safety are carried out mainly by the Anti-Adulteration and Health Units (NAS) of the Carabinieri and by the veterinary services and food hygiene departments of the Local Health Authorities (ASL). These bodies carry out periodic inspections at supermarkets to verify compliance with food regulations. However, the frequency and depth of these controls vary considerably between different regions and depending on available resources.

According to data from the Ministry of Health, in 2022, over 50,000 inspections were carried out in the food sector, with a non-compliance rate of about 15%. Regarding mushrooms specifically, controls focus mainly on verifying the accompanying documentation and the correct identification of the species. In case of doubt, mushrooms can be subjected to laboratory analysis to confirm identification or detect the presence of toxins.

System criticalities: staff training and sampling

One of the main critical issues concerns the training of supermarket staff. Often the employees in the fruit and vegetable department do not have sufficient mycological skills to recognize possible anomalies or suspicious species. This can delay the identification of problems and the withdrawal of potentially dangerous products.

Another criticality concerns the representativeness of sampling: mycological controls are carried out on samples from each batch, but it is not possible to check every single mushroom. This means that, especially when mushrooms are fragmented or in a poor state of preservation, toxic specimens mixed with edible ones might escape detection. Furthermore, dried or preserved mushrooms present additional identification difficulties, as macroscopic characteristics can be altered by preservation processes.

 

Statistics and data on mushroom poisoning in Italy

Epidemiological data on mushroom poisoning provides valuable information to evaluate the effectiveness of control systems and identify critical issues. In this section, we will analyze the official statistics on mushroom poisoning in Italy, distinguishing between those caused by self-collected mushrooms and those related to mushrooms purchased in large-scale retail.

National data: the annual report of the ministry of health

According to the latest available report from the Ministry of Health, in Italy there are approximately 400-500 cases of mushroom poisoning each year, with about ten deaths. The vast majority of these poisonings (about 90%) are caused by mushrooms collected independently and not subjected to mycological control. Only a small percentage (about 5%) is attributable to mushrooms purchased through commercial channels, including supermarkets.

However, it is important to note that cases related to large-scale retail, although rare, can involve a larger number of people simultaneously, as a contaminated batch can be distributed to different points of sale. Furthermore, cases involving mushrooms purchased at the supermarket often have greater media resonance, contributing to creating alarm among consumers.

2021398921Amanita phalloides, Lepiota brunneoincarnata
20224351018Amanita phalloides, Entoloma sinuatum

Regional analysis: where poisonings are concentrated

The geographical analysis of the data shows that mushroom poisonings are not uniformly distributed across the national territory. The regions of Northern Italy, where the tradition of mushroom picking is more rooted, record the highest number of cases, with Piedmont, Lombardy, and Veneto at the top of the ranking. In contrast, the regions of the south and the islands record a significantly lower number of poisonings.

This geographical distribution reflects not only consumption habits but also the effectiveness of regional control systems. Some regions have implemented more rigorous control systems and more effective information campaigns, which help reduce the number of poisonings. Furthermore, the presence of specialized poison control centers in some regions can influence the detection and reporting of cases.

 

Practical advice for the consumer: how to buy safe mushrooms at the supermarket

Despite the checks carried out by the authorities and the supermarkets themselves, the consumer plays a fundamental role in their own food safety. In this section, we will provide practical advice for recognizing and buying safe mushrooms at the supermarket, indicating what to check before purchase and how to behave in case of doubt.

Visual checks: what to observe before purchase

Before buying fresh mushrooms at the supermarket, it is important to perform some basic visual checks: Verify that the mushrooms are in a good state of preservation, without signs of decomposition, mold, or parasites.. Mushrooms should be firm to the touch, with lively and characteristic colors of the species. Avoid buying mushrooms that appear soft, slimy, or with unpleasant odors.

Check that the labeling is complete and correct: The label must report the scientific name of the mushroom, the commercial name (if provided), the country of origin, and, ideally, the reference to the mycological control carried out. If the labeling is incomplete or unclear, it is better to avoid the purchase.

Risky behaviors to avoid

There are some behaviors that increase the risk of poisoning, even when buying mushrooms at the supermarket: Never mix different species of mushrooms during storage or preparation, as this could make it difficult to identify the possible toxic species responsible for poisoning. Always store mushrooms in separate containers and, if possible, consume only one species per meal.

Another risky behavior is consuming mushrooms in large quantities or giving them to children, the elderly, or people with health problems without adequate precaution. M ushrooms are complex foods that can cause individual reactions even in species normally considered edible. It is always advisable to consume small quantities the first time you try a new species, even if purchased at the supermarket.

 

Supermarkets: between perceived safety and real risks

In conclusion, the mushroom control system in Italian supermarkets, although not perfect, generally offers good safety guarantees. However, the complexity of the fungal world and the possible critical issues in the supply chain require consumers to maintain a conscious and informed approach. 

The data analyzed in this article show that the risk of poisoning from mushrooms bought at the supermarket is significantly lower than that associated with self-collected mushrooms. However, sporadic cases of poisoning related to large-scale retail demonstrate that the system is not infallible. The main critical issues concern staff training, the representativeness of sampling, and the possible confusion between similar species.

To further improve safety, it would be advisable to implement more advanced traceability systems, allowing quick tracing back to the origin of each batch of mushrooms. Furthermore, it would be useful to develop rapid analysis protocols to detect the presence of specific toxins, complementary to the visual control carried out by mycologists. Finally, more effective information campaigns could help consumers recognize warning signs and adopt safer behaviors.

Ultimately, food safety is a shared responsibility between authorities, sector operators, and consumers: while supermarkets and control authorities must ensure that products placed on the market are safe, consumers must do their part by purchasing consciously and following good storage and preparation practices. Only through this integrated approach is it possible to further minimize the already low risks associated with the consumption of mushrooms purchased in large-scale retail.
