Summary: Food and feed safety is a major concern for both animal and human health, as contamination with pathogens can occur frequently. This study investigated the effects of simultaneous contamination with mycotoxins and bacterial toxins on cell viability, oxidative stress, and inflammation. The results showed significant additive/synergistic effects of co-exposure to fungal and bacterial toxins, suggesting that the concomitant contamination with bacteria and mycotoxins could lead to higher toxicity.

Summary: Little information is available regarding the feeding of dairy cattle in Sri Lanka or the impact of feeding on productivity. This study investigated the availability and composition of feeds in Sri Lanka and found that the majority of the feed types used in medium-scale dairy farms are insufficient to meet the nutritional requirements of lactating and dry cows. There is a consistent shortfall in the energy and protein intake of cows, leading to limitations on milk production.

Summary: This study investigated the toxic impacts of zearalenone and trifloxystrobin on zebrafish. The results showed that zearalenone had a lower lethal toxicity compared to trifloxystrobin and their mixture induced a synergistic effect on embryonic fish. Additionally, the combination of these chemicals led to more significant changes in the expression levels of certain genes. Thus, assessing the risk based on the combined impact of these chemicals is more accurate than evaluating them individually.

Summary: Several studies have demonstrated the toxicity of both aspartame (ASP) and aflatoxin B-1 (AFB(1)) separately, but little is known about their concomitant exposure and hazardous consequences. In this study, male rats were exposed to AFB(1), ASP, or both substances for 14 days. The results showed that the combination of ASP and AFB(1) had greater behavioral impairments and oxidative status imbalance compared to the groups treated with only ASP or AFB(1). These findings suggest that the co-exposure to ASP and AFB(1) disrupts brain homeostasis.

Summary: Following a request from the European Commission, the FEEDAP Panel assessed the safety of Calsporin (Bacillus velezensis DSM 15544) as an additive for dairy cows and other dairy ruminants. The active ingredient, B. velezensis DSM 15544, was considered safe for the target species, consumers, and the environment. The additive was found to not be a dermal/eye irritant but should be considered a respiratory sensitiser. However, efficacy conclusions could not be drawn based on the provided data.

Summary: This study aimed to determine and minimize aflatoxin contamination in locally made complementary food composite to reduce exposure to weaning children. The concentrations of total aflatoxin (TAF) and aflatoxin B1 (AFB1) were established along the processing points of locally made malted millet sesame soybean composite (MMSSC) during wet and dry seasons. The study found that all samples had detectable concentrations of TAF and AFB1, with contamination being highest in raw materials and varying significantly across seasons. The exposure to these toxins was higher than the acceptable limits, emphasizing the need to reduce children's exposure and take proper storage measures.

Summary: Pigs' health and growth performance are negatively affected by exposure to deoxynivalenol (DON). The measurement of DON in feed and diets is inconsistent due to the uneven distribution of mycotoxins and difficulties in obtaining representative samples. However, this study found that analyzing DON levels in urine and blood serum can be used to predict a pig's DON intake, as there is a positive correlation between DON intake and urinary and serum DON concentrations when samples are collected under controlled conditions.

Summary: This study investigated the effects of different grape and winery by-products on ruminal microbiota and fermentation characteristics. The results showed that the addition of grape seed meal and grape pomace can reduce excessive ammonia production, and high dosage of grape phenols can alter the rumen microbial community. However, dosage plays a dominant role in affecting the microbial activity compared to the form or source of grape phenols.
