Dietary aflatoxin B1-related risk factors for the presence of aflatoxin M1 in raw milk of cows from Ecuador.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Aflatoxin M1 (AFM1) is hepatotoxic and carcinogenic, and it may be present in milk due to dairy cow's ingestion when feed is contaminated with Aflatoxin B1 (AFB1). Aim: The objective of this research was to determine the potential risk factors of dietary AFB1 contamination in dairy cows, which causes AFM1 contamination of the raw milk, through an epidemiological survey and statistical analysis. Methods: 209 raw milk samples were collected, and AFM1 concentrations were detected by lateral flow immunochromatographic assay. Results: It was determined that 100% of the samples contained concerning levels of this mycotoxin with a mean of 0.077 μg/kg, which exceeds the maximum allowed by the European Union legislations (0.05 μg/kg) but not Ecuadorian Regulations (0.5 μg/kg). An adjustment to a linear model by weighted least squares was used to correct the presented heteroscedasticity. Potential risk factors for dietary AFB1 contamination were analyzed in relation to the appearance of AFM1 in milk from Ecuador. Among factors including legumes consumption, the use of silage, type of production system (intensive, extensive, and mixed), and farm size (small, medium, and big), the intensive production system and the big producers presented higher levels of AFM1. Conclusion: Considering that all the milk samples presented AFM1 and since there is no specific feed determined to be a risk factor, it was concluded that any of the feed offered to dairy cows may be contaminated with AFB1. It is necessary to reduce AFB1 levels in feed by implementing good agricultural practices and improving feed storage to decrease milk AFM1 levels. This study identified that intensive systems have a lot of animals, and silage is incorporated into the diet, which can significantly increase AFM1 levels.
