Research – Effects of oilseed substrates (ground nyjer and flax seeds) on the growth and Ochratoxin A production by Aspergillus carbonarius

Wiley Online

Aspergillus carbonarius is one of the major Ochratoxin A (OTA) producing fungus. Nyjer and flax seeds are important oilseeds that are used for both human and animal consumption, but they are highly susceptible to fungal growth and mycotoxin contamination. The objectives of this study were to determine the growth and OTA production by A. carbonarius on ground nyjer and flax seeds with water activity levels ranging from 0.82 to 0.98 aw at three incubation temperatures (20, 30, 37°C). It was found that A. carbonarius was not able to grow on the two types of oilseeds with 0.82 or 0.86 aw. Also, the fungus was not able to grow on flax seeds with high water activity (0.98 aw). The OTA was only detected on flax seed samples with 0.94 aw at 20°C. On nyjer seeds, the highest concentration of OTA (271 μg/kg) was detected from samples with 0.98 aw incubated at 20°C for 5 days, while on flax seeds the highest OTA (146 μg/kg) was found on the seed samples with 0.94 aw incubated at 20°C for 15 days. Linear regression models also indicated that 0.98 aw was optimal for both fungal growth and OTA production on nyjer seeds. Overall, ground nyjer seed is better than flax seed to support growth and OTA production by A. carbonarius .

Research – Ochratoxin A in food: public health risks assessed

EFSA

EFSA has published a scientific opinion on public health risks related to the presence of ochratoxin A (OTA) in food – a mycotoxin naturally produced by moulds that can be found in a variety of foodstuffs including cereals, preserved meats, fresh and dried fruit, and cheese.

New data that have become available since the last assessment in 2006 suggest that OTA can be genotoxic by directly damaging the DNA. Experts also confirmed that it can be carcinogenic to the kidney. Therefore experts calculated a margin of exposure (MOE). This is a tool used by risk assessors to consider possible safety concerns arising from the presence in food and feed of substances which are both genotoxic and carcinogenic.

In its previous opinion, EFSA established a tolerable weekly intake (TWI) based on toxicity and carcinogenicity to the kidney.

Experts have now used a more conservative approach by calculating MOE and concluded that there is a health concern for most consumers groups. EFSA’s scientific advice will inform the European Commission in the ongoing discussion on maximum levels of OTA in foodstuffs.

EFSA consulted stakeholders and different parties on its draft opinion and comments received were considered when finalising it.

Food Safety News

Ochratoxin A in food poses a health concern for most consumer groups, according to a European Food Safety Authority (EFSA) assessment.

Ochratoxin A (OTA) is a mycotoxin naturally produced by molds that can be found in foodss such as cereals, preserved meats, fresh and dried fruit, and cheese.

Data available since an opinion in 2006 suggest that OTA can be genotoxic by directly damaging the DNA and experts confirmed it can be carcinogenic to the kidney. OTA causes kidney toxicity in different animal species and kidney tumors in rodents.

The European Commission asked EFSA to update the 2006 opinion. In that work, a tolerable weekly intake (TWI) based on toxicity and carcinogenicity to the kidney of 120 nanograms per kilogram (ng/kg) of body weight was established.
