The impact of certain flavourings and preservatives on the survivability of eggs of Ascaris suum and Trichuris suis

Abstract

The article describes a laboratory study of nematocidal properties of flavourings with antibacterial effect against Ascaris suum (Goeze, 1782) and Trichuris suis Schrank, 1788. In the experiments, eight concentrations of food additives with antibacterial properties were used: cinnamaldehyde, benzoic acid, formic acid, linalool, citral, β-ionone. Minimum LC50 value for eggs of A. suum was observed while using cinnamaldehyde and benzoic acid – 1.62 ± 0.37% and 1.69 ± 0.14%, and for eggs of T. suis – 0.57 ± 0.03% and 1.80 ± 0.11% respectively. The lowest influence on the development of eggs of nematodes of pigs’ A. suum and T. suis was exerted by formic acid, linalool, citral and β-ionone. In eggs of A. suum and T. suis, larvae formed in 21 and 50 days even during exposure to 3% emulsions of these substances. The strongest negative impact on the eggs of parasitic nematodes was displayed by cinnamaldehyde flavouring. Further study on nematocidal properties of flavourings, as well as their mixtures, would contribute to the development of preparations which would have a strong effect on eggs and larvae of nematodes of animals and humans.

Nematicidal Activity of Inorganic Food Additives

“…During the migration through food chains, those sub-stances end up in the organisms of animals and contaminate agricultural products [29,30]. Over recent years, alternative substances to combat pests have become broadly distributed: there are compounds that already exist in nature, such as medicinal plants [45][46][47], their essential oils [48,49], and also substances used in the food industry [50,51]. Some inorganic food additives, including alkalis, acids and salts may have negative effects on nematode larvae-parasites of agricultural animals.…”

Features of exogenous development of Trichuris globulosa (Nematoda, Trichuridae)

“…Gastrointestinal nematodes cause common and very important from an economic point of view diseases of both domestic and wild animals around the world (Little, 2011;van der Voort et al, 2013;Ananta et al, 2014;Marskole et al, 2016;Susana et al, 2019). Among them, the most significant are zoonotic helminthiases which affect humans by the same stages of the pathogen that live in the animal bodies (Bawm & Htun, 2015;Boyko & Brygadyrenko, 2017, 2019, 2020. Such dangerous parasites include nematodes of the genus Trichuris Röderer, 1761, hematophagous helminths which have a significant distribution and species diversity (Ghai et al, 2014;Susana et al, 2019).…”
