It is also known that by adding paranitrophenol and dehydroacetic acid or paraffin it is possible to delay or fully prevent mould development, but at the same time they frequently reduce rodent bait acceptance (Buckle, 1994).…”

SUMMARYThe aim of our study was to investigate the possibility of application of essential oils as additives in cereal-based rodenticide baits, at rates which prevent mould development and are applicable in humane medicine. Also, the purpose of these oils would be to extend the utility value of baits and reduce the use of antifungal ingredients that usually affect bait acceptance.The effects of essential oils of ten different plant species, applied at rates of one and two ml per kg of plain bait, on bait acceptance and palatability in choice feeding tests for Swiss mice were studied under controlled laboratory conditions. Baits were prepared according to relevant EPPO standards (2004). The effects of essential oils on bait acceptance and palatability for Swiss mice were determined in choice feeding tests using a formula by Johnson and Prescott (1994).There was no significant statistical difference in effects between groups and sexes regarding weight change in the experiment. During the experiment and recovery period, neither change in mice behavior no deaths were observed. Cinnamon and anise essential oils, commonly used as attractants, and clove oil, were most effective because they had no negative effect on bait acceptance and palatability, while fenchel and bergamot oils showed repellent activity that grew as the oil content in baits increased.

“…The most of these inhibitors are plant-derived such as phenylpropanoids, terpenoids and alkaloids [8]. A group of plant-derived inhibitors is essential oils that possess antimicrobial activities against A. parasiticus and/or A. flavus [9][10][11][12].…”

The hazardous nature of aflatoxins to human and animals necessitate the need for establishment of control measures. The objective of this study was to evaluate the inhibition of growth and aflatoxin production of Aspergillus flavus strain (ATCC 16872) by various essential oils in Yeast Extract Sucrose (YES) growth media at 25°C. Essential oils of basil, fennel, coriander, caraway, peppermint and rosemary were tested for their effects on mycelial growth and aflatoxin production. Aflatoxin B1 production was determined by high performance liquid chromatography (HPLC). The findings of this study revealed the antifungal efficacy of the all tested essential oils. The extent of inhibition of fungal growth and aflatoxin production was dependent on the type and concentration of essential oils used. The complete inhibition of Aspergillus flavus growth was observed at 1000 ppm concentrations of essential oils of basil, coriander, caraway and rosemary. While, essential oils of basil and coriander showed marked inhibition of aflatoxin B1 produced by Aspergillus flavus at all concentrations tested 500,750 and 1000 ppm.

“…AFs are of great concern due to their detrimental effects on the health of humans and animals (Zinedine and Manes, 2009). AFs are the most common and probably the most significant mycotoxin in terms of human and animal health risk (Sauer, 1988;Bluma and Etcheverry, 2008). …”

“…Moreover, AFB1 are known to be highly toxic and several studies have shown to be carcinogenic, tetragenic, mutagenic, hepatotoxic, genotoxic, immune suppression, growth retardation, and inhibit several metabolic systems in humans and other animal species (Zinedine and Manes, 2009;Bluma and Etcheverry, 2008;Shephard, 2003). AFB1 classified by the International Agency for Research on Cancer (IARC) as a class 1 carcinogen to humans (IARC, 1993).…”

Agriculture is the backbone of Tanzanian economy. It accounts for about one-third of the gross domestic product (GDP), provides 85 percent of all exports and saves as a livelihood to over 80 percent of the total population. Maize is the primary staple crop; it's grown in nearly all agro-ecological zones in the country. Tanzania is a major maize producer in Sub-Saharan Africa. In the last four decades, Tanzania has ranked among the top 25 maize producing countries in the world. In the 2013/14 growing seasons Tanzania produced over half billion metric tons of maize of these maize smallholder farmers produced around 85%. Despite the steady production of maize over the past three decades, post-harvest losses of maize remained significant, up to 30-40 % in some rural areas. Post-harvest handling, poor infrastructure, weather variability, biotic factors such as insects and pests, bacteria, pathogens, viruses, and fungi, often aggravate such losses. Mycotoxin producing fungi pose a major risk. Mycotoxins are toxic secondary metabolites of fungi that frequently contaminate the maize in the field and/or during storage. Mycotoxin contamination of maize poses a health risk to humans and animals if not properly managed. The most important mycotoxins in Tanzania are the aflatoxins, fumonisins and Ochratoxin. The objective of this paper was to review current literature on the production trends, consumption, post-harvest losses, and mycotoxins contamination of maize and to provide strategies to control and prevent postharvest losses and mycotoxins contamination in Tanzania.
