These pathogens produce different mycotoxins such as ochratoxins, aflatoxins, and <em>Fusarium</em> toxins. Based on literature review we recommend that advance agronomic practices, molecular techniques, breeding practices and post-harvest management can help to reduce the risk of mycotoxins accumulation.

A key test in the development and quality control of antivenoms has been the neutralization of the lethal effect of venoms. Since the early times of antivenoms, the neutralization of venom's lethality has been predominantly based on the incubation of venom and antivenom prior to the injection in laboratory animals. The present narrative review summarizes the main milestones in the development of venom neutralization assays by antivenoms, starting with the pioneer work of Albert Calmette and Vital Brazil. Despite various initiatives along the 20th century to standardize these tests, the antivenom efficacy assays have been highly heterogeneous between laboratories and countries. Efforts carried out to understand the main variables that determine the lethality neutralization tests are discussed, together with the introduction of assays to assess the neutralization of other relevant toxic and enzymatic activities of venoms, which complement the lethality assay. In the last decades, international efforts coordinated by the World Health Organization (WHO) led to the publication of the WHO guidelines for the production and control of antivenoms, which comprise detailed descriptions of preclinical neutralization assays, including the essential test, i.e., lethality, and supplementary assays that assess other relevant toxic effects. The pain and suffering of animals in the traditional antivenom neutralization tests urge the implementation of the 3Rs principles (replacement, reduction, refinement) in antivenom efficacy assessment, and innovation is urgently needed in this field.</div></div>","PeriodicalId":23289,"journal":{"name":"Toxicon","volume":"256 ","pages":"Article 108274"},"PeriodicalIF":2.6,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143374730","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Physiological adaptations for venom resistance have been identified in various snake prey species, but fewer snake predators, with research in this area largely biased towards mammalian species. Fewer investigations have assayed for the presence of resistance mechanisms in avian systems. Birds of prey (hereafter “raptors”; orders Accipitriformes, Falconiformes, and Strigiformes) represent major sources of predation for snakes. Raptor dietary habits range from snake specialists to non-snake feeders, and this continuum of snake predation frequency among species creates the ideal system in which to explore the presence and strength of venom resistance. We assayed sera from a suite of Great Plains raptors against snake venom metalloproteinases (SVMPs) of the Prairie rattlesnake (<em>Crotalus v. viridis</em>) to test the general hypotheses that 1) raptor sera will display elevated SVMP inhibition compared to a naïve avian model (domestic chicken; <em>Gallus gallus</em>) and 2) raptor species with high levels of rattlesnake predation will more effectively inhibit SVMP activity than those that are not known to feed on rattlesnakes. We found that raptors do possess elevated SVMP inhibition in comparison to a naïve avian model, but this level of inhibition remains low and is unlikely to be biologically significant in detoxifying venoms. We found no evidence suggesting that inhibitory potential of different raptor sera corresponds to the level of rattlesnake predation associated with each species. The widespread lack of SVMP inhibition in diverse raptors underscores the complexity of venom resistance dynamics in natural systems and further suggests that physiological venom resistance mechanisms may be poorly developed in birds more broadly.</div></div>","PeriodicalId":23289,"journal":{"name":"Toxicon","volume":"256 ","pages":"Article 108275"},"PeriodicalIF":2.6,"publicationDate":"2025-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143349273","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
