Insights

This study identified mould strains on Istrian ham, finding common species like Eurotium, Aspergillus, and Penicillium. Importantly, none of the isolated moulds produced mycotoxins, ensuring Istrian ham safety.

Area of Science:

  • Food Microbiology
  • Mycology
  • Food Safety

Background:

  • Istrian ham production involves specific pre-ripening and ripening phases.
  • Mould growth on cured meat surfaces can impact quality and safety.
  • Understanding the microflora is crucial for ensuring food safety.

Purpose of the Study:

  • To identify mould strains present on Istrian ham during ripening.
  • To assess the toxic potential of these isolated mould strains.
  • To determine the health implications for consumers.

Main Methods:

  • Isolation and identification of mould species from Istrian ham surfaces.
  • Culturing moulds under simulated ripening conditions.
  • Testing isolated strains for mycotoxin production.

Main Results:

  • Five main mould genera were identified: Eurotium, Aspergillus, and Penicillium were predominant.
  • Mould species remained consistent between pre-ripening and ripening phases.
  • Mould presence and growth were influenced by ripening temperature and humidity.
  • None of the tested mould isolates were found to produce mycotoxins.

Conclusions:

  • Istrian ham microflora is primarily influenced by environmental contamination from air and ripening chambers.
  • The identified mould strains do not pose a health risk due to a lack of mycotoxin production.
  • Istrian ham is safe for consumption regarding mould-related mycotoxin hazards.

Fungal Group Zygomycota

Zygomycota, previously classified as a distinct fungal group, are primarily terrestrial, saprophytic molds that play a crucial role as decomposers. Recent phylogenetic studies have revealed that these fungi are now divided into two major clades — Mucoromycota, which includes many symbiotic species, and Zoopagomycota, which primarily consists of parasitic and pathogenic fungi. These groups exhibit distinct ecological roles and reproductive strategies while sharing key structural and...

Microbial Spoilage of Food

Microbial food spoilage refers to the degradation of food quality resulting from the metabolic activity of microorganisms such as bacteria, yeasts, and molds. These microbes proliferate on various food substrates depending on factors such as moisture content, nutrient availability, and storage conditions, leading to undesirable sensory and structural changes.Bacteria are primary agents of spoilage in high-moisture, nutrient-dense foods like meat, milk, and vegetables. Microbial spoilage occurs...
