Prevalence of fungi and aflatoxin contamination in stored groundnut in Ghana

Aflatoxins in randomly selected groundnuts (Arachis hypogaea) and its products from some local markets across Ghana: Human risk assessment and monitoring

“…The results obtained in this study were higher than the values reported in several related works. Recently, Asare- Bediako et al [ 38 ] and Agbetiameh et al [ 55 ] reported mean values of 928.7 ng/g and 145.6 ppb in groundnut samples from the Upper West and Brong Ahafo regions of Ghana respectively. Sugri et al also reported 250 ppb for samples from Bantanarigu in the Upper Regions of Ghana.…”

“…There is sufficient evidence from pertinent literature ([ 5 , 38 , 2 , 58 ]) points that post-harvest aflatoxin contamination of groundnuts is still a major problem in Ghana and probably in most West African groundnut-producing countries too. Worthy of note, there was an observed comparatively high toxin levels in groundnut paste as found in kernels, and this could be attributed to the inferior quality of kernels used for preparing groundnut paste.…”

“…Raw groundnut samples and groundnut paste samples were randomly purchased from different markets across the different regions in Ghana ( Table 1 ) from the period of February to September 2019 and grouped into 2 categories (groundnuts and groundnut paste) (Tables Table 3a , Table 3b , Table 3c , Table 4a , Table 4b , Table 5 , Table 6 – 7 ). Twenty (20) grams each of the samples were fetched and stored in sterile bags in an ice chest at −4 °C and transported to the laboratory and kept in a deep freezer prior to chemical exploration [ 38 ].…”

Aflatoxin contamination in groundnut (Arachis hypogaea L.); its causes and management

“…In Ghana, aflatoxin levels in groundnut were reported to be 216 µg/g while groundnut paste had 3,278 µg/g and groundnut sauce 943 µg/g (Alakonya and Monda, 2013). According to Bediako et al (2019), findings shown that aflatoxin contamination in Ghana exceeded the acceptable limit of 20 ppb set by Ghana Standard Authority. Moreover, a study in Kenya also indicated that, 37% of groundnuts and its products did not meet the total aflatoxin limit set by Kenya Bureau Standard of 10 µg/kg (Ncube and Maphosa, 2020).…”

Genetic Variation and Aflatoxin Accumulation Resistance among 36 Maize Genotypes Evaluated in Ghana

“…Identification slides were prepared by picking spores with isolation needle onto a slide containing a drop of distilled water. A. flavus was subsequently identified by observing colony characteristics, conidial morphology as described previously [7,8].…”
