“…M. avium ssp. hominissuis was the most isolated causative agent in several studies [ 121 , 122 , 123 , 124 , 125 , 126 ]. It is very difficult to remove NTM from naturally infected peat by any disinfection procedure currently practiced including treatment with high temperatures [ 127 ].…”

Nontuberculous Mycobacteria as Sapronoses: A Review

et al. 2022

Mycobacteria are a unique group of microorganisms. They are characterised by exceptional adaptability and durability. They are capable of colonisation and survival even in very unfavourable conditions. In addition to the well-known obligate human pathogens, Mycobacterium tuberculosis and M. leprae, more than 200 other species have been described. Most of them form a natural part of the microflora of the external environment and thrive in aquatic and soil environments especially. For many of the mycobacterial species associated with human disease, their natural source has not yet been identified. From an ecological point of view, mycobacteria are saprophytes, and their application in human and animal diseases is opportunistic. Most cases of human disease from saprophytic mycobacteria occur in immunocompromised individuals. This adaptability and resilience to environmental pressures makes treatment of mycobacterial diseases (most often sapronoses and less often zoonoses) and permanent eradication of mycobacteria from the environment very difficult. Saprophytic mycobacterial diseases (sapronoses) are chronic and recurrent due to the fact of repeated endogenous or exogenous re-exposure. Therefore, knowledge regarding their occurrence in soil and dust would aid in the prevention of saprophytic mycobacterioses. In conjunction, their presence and ecological significance in the environment can be revealed.

“…Another major difference between conventional and alternative farms (organic farms or farms participating in specific animal welfare programs) is that the latter often use straw as a bedding material in the stables, while conventional farms often use slatted floors. This aspect might also have an impact on LA-MRSA: while slatted floors are apparently easier to clean, one can hypothesize that straw is an organic material containing a variety of bacteria [ 23 ] that might reduce LA-MRSA in the environment by competitive effects.…”

Pilot Study on Alteration of LA-MRSA Status of Pigs during Fattening Period on Straw Bedding by Two Types of Cleaning

et al. 2021

In countries with professional pig husbandry in stables, the prevalence of livestock-associated (LA) methicillin-resistant Staphylococcus aureus (MRSA) on farms has remained high or has further increased in recent years. Simple measures to reduce LA-MRSA among pigs have not yet been successfully implemented. The aim of this pilot study is twofold: first, to examine how the LA-MRSA status of LA-MRSA positive fattening pigs at the date of housing changes over the fatting period on straw bedding and, second, whether this change could be influenced by the quality of cleaning and disinfection (C&D). For this purpose, 122 animals are individually tested for LA-MRSA carriage at five sequential time points comparing pigs housed on a farm using straw bedding plus C&D (n = 59) vs. straw bedding plus simple cleaning (n = 63). At the time of housing, all animals in both groups are LA-MRSA positive. This status changes to 0% in the group with simple cleaning until the end of fattening and 28% in the C&D group. LA-MRSA in environmental and air samples is also reduced over the fattening period. The results indicate that keeping pigs on straw might be one way to reduce LA-MRSA during the fattening period with simple cleaning appearing to be more beneficial than C&D. Further investigations are necessary to determine the influencing factors more precisely.

“…A further point of concern is the possible introduction of pathogenic microorganisms with enrichment or bedding materials. This has been described for peat (Matlova et al 2012;Wagner et al 2018) and recycled sand (Kristula et al 2005). Little is known about the movement of animal toys between stables and their re-use for different flocks or herds.…”

The main objectives of EFSA's activities on emerging risks are: (i) to carry out activities to identify emerging risks; (ii) to develop and improve emerging risk identification (ERI) methodologies and approaches; and (iii) communicate the issues and risks identified. The outcome of these activities also allows EFSA to prepare for future risk assessment challenges. The current technical report summarises the activities of all groups involved in the ERI procedure, the issues identified in the course of 2020, a description of the methodologies that have been considered, and collaborative activities. EFSA networks of knowledge contributing to the ERI activity include the Emerging Risks Exchange Network (EREN), the Stakeholder Discussion Group on Emerging Risks, EFSA's scientific units, scientific panels and the Scientific Committee. In total, 13 potential emerging issues were discussed in 2020. Six were concluded to be emerging issues. The potential issues were organised according to the hazard or driver identified. In addition, in 2020, EREN network members presented and discussed a total of 35 signals/potential emerging issues that had been identified by their own horizon‐scanning activities. Member State representatives shared their work on signal identification with the objective of collecting additional information that could be used for better characterisation. It is crucial to introduce more dynamic and interactive approaches to gather and disseminate knowledge, while also taking into consideration the potential risks that may arise in new areas.
