“…The reported aflatoxin B1 values were higher than raw milled rice, where enhanced fungal growth is expected anyway due to high humidity and temperature in their storage conditions ( Bandara et al. 1991 ; Manage and Dissanayake 2009 ; Karunarathna et al. 2019 ).…”

Aflatoxin B1 contamination adversely affects human health by impairing long-term physical and cognitive development. Several crops have been associated with aflatoxin B1 contamination and corn is one of them. In the Anuradhapura district of the North Central Province of Sri Lanka, corn is one of the main agricultural produce. Due to poor farming practices in this area, it is possible that aflatoxin B1 is somehow transported from soil to the corn ears. This study was carried out to detect and quantify aflatoxin B1 in corn and corn-grown soils in Anuradhapura. Corn (n = 60) and corn-grown soil (n = 60) samples were randomly collected from 20 minor-scale corn-grown fields with three random replicates. Each sample was prepared for the measurement of aflatoxin B1 levels using the Enzyme-Linked Immunosorbent Assay (ELISA). Though 20 ppb is considered as the poisonous or deleterious level for corn consumption, there were toxin contaminations of up to 60–70 ppb in the corn kernel, while majority of soil had 350–400 ppb of aflatoxin B1 levels. Fifteen corn samples had exceeded the acceptable level while 22 samples were free of aflatoxin B1 and 23 samples were within the acceptable level. The results showed that the presence of aflatoxin B1 in corn is not habitually distributed throughout Anuradhapura district and it increased with the soil aflatoxin B1 concentration. It appears that there is a relationship between corn kernel and corn-grown soil aflatoxin B1 levels.

“…According to a survey conducted in Sri Lanka, edible vegetable oil types obtained from the Sri Lankan market, peanuts, peanut-based products and parboiled rice were reported with significantly high aflatoxin B1 and aflatoxin G1 contents ( Bandara et al. 1991 ; Manage and Dissanayake 2009 ; Karunarathna et al. 2019 ).…”

“…Consumers used edible oil in daily life because it has functions in preventing arteriosclerosis and reducing blood lipid [2][3]. Increasing awareness and having more health benefits of using vegetable oils have boosted its demand and consumption worldwide, especially in developed countries [4]. Worldwide, the highly popular oils are maize oil, olive oil, peanut oil and sunflower, and the consumption rate of these oils is rising.…”

A total of 744 samples of vegetable seeds and oil (soybean, sunflower, canola, olive, corn, and mustard) were collected for the presence of aflatoxin B1 (AFB1) and total aflatoxins (AFs). The results have shown that 92 (56.7%) samples of branded and 108 (57%) samples of non-branded edible seeds were observed to be contaminated with AFs. The maximum mean of AFB1 and total AFs in non-branded soybean seeds was 21.01 ± 4.70 and 36.37 ± 6.10 µg/kg, respectively. Furthermore, all samples of edible seeds have concentrations of AFB1 greater than the proposed limit of European Union (EU, 2 µg/kg) and 12 (7.40%) samples of branded seeds and 14 (7.40%) samples of non-branded seeds were found in the range ≥ 50 µg/kg. About 78 (43.3%) samples of branded edible oil and 103 (48.3%) sample of non-branded edible oil were observed to be positive with AFs, and the elevated average of AFB1 (14.29 ± 2.51 µg/kg) and total AFs (25.61 ± 7.50) µg/kg were found in non-branded soybean oil samples. Furthermore, 16 (8.88%) and 6 (3.33%) samples of branded vegetable oil have levels of total AFs in a range (21 - 50 µg/kg) and ≥ 50 µg/kg, respectively. The findings have indicated significant difference of AFs levels between branded and non-branded vegetable oil samples (t = 22.274 and p = 0.000) at α = 0.05 and significant difference of AFs levels in vegetable seeds and oil samples ( t = -17.75, p = 0.000) at α =0.05. The highest dietary intake was found in non-branded sunflower oil sample (0.90 µg/kg/day) in female individuals (16-22 age group), followed by the dietary intake of 0.69 µg/kg/day body weight in male individuals (16-22 age group).

Nowadays, the popularity of plant-based edible oils is on the rise; they are gaining the interest of consumers because of their functional and health-promoting properties (Vasseghian et al., 2020). Moreover, consumers are increasingly choosing nontraditional oils in search of new food sensory properties and greater functionality.For this reason, edible oils prepared from sea buckthorn, mustard, flaxseed, hempseed, and camelina seeds at small-scale agriculture companies are gaining popularity.Oil prepared from sea buckthorn has a high content of palmitoleic acid; however, oils prepared from seeds and pulp have a different fatty acid (FA) profile (Ciesarová et al., 2020). Sea buckthorn seeds contain 12.5% oil, and the whole fruits, on average, 10% (Zielińska & Nowak, 2017). In addition, sea buckthorn is rich in tocopherols and other bioactive compounds (Olas, 2018;Tudor et al., 2020).
