Summary
Mycotoxin contamination in animal feed is widespread globally, affecting 88% of samples. Climate significantly influences regional occurrence, with notable aflatoxin B1 exceedances in South and Southeast Asia.
Area of Science:
- Food Science
- Animal Nutrition
- Environmental Science
Background:
- Mycotoxins in animal feed pose risks to animal health and food safety.
- Global monitoring of mycotoxin contamination is crucial for risk assessment.
Purpose of the Study:
- To conduct a large-scale global survey of mycotoxin contamination in animal feed.
- To assess regional differences and temporal variations in mycotoxin occurrence.
- To identify key factors, such as climate, influencing mycotoxin contamination patterns.
Main Methods:
- Analysis of aflatoxin B1, zearalenone, fumonisins, ochratoxin A, deoxynivalenol, and T-2 toxin.
- Testing of 74,821 feed and feed raw material samples from 100 countries (2008-2017).
- Statistical analysis to identify regional trends, climate correlations, and co-contamination patterns.
Main Results:
- 88% of samples contained at least one mycotoxin.
- Distinct regional trends were observed, with climate as a key determinant.
- High levels of aflatoxin B1 exceeded EU limits in 41.1% (South Asia), 38.5% (Sub-Saharan Africa), and 20.9% (Southeast Asia) of samples.
- 64% of samples showed co-contamination with two or more mycotoxins, frequently deoxynivalenol, zearalenone, and fumonisins.
Conclusions:
- Mycotoxin co-contamination in animal feed is a common global issue.
- Climate and weather patterns significantly influence the regional distribution and year-to-year variability of mycotoxins.
- Targeted monitoring and risk management strategies are essential, particularly in vulnerable regions.

GPS surveying methods vary in application, accuracy, and data collection techniques, catering to diverse surveying and mapping needs. Static GPS, kinematic GPS, and real-time kinematic (RTK) surveying are widely used. Each technique offers distinct advantages.Static GPS involves placing one receiver at a known reference point and another at the target point. It collects exact positional data by observing multiple satellite ranges over an extended period, achieving centimeter-level accuracy for...

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Surveying is the art and science of mapping the earth's surface. It involves measuring distances, angles in horizontal or vertical directions, and levels to understand the shape and size of land features. Surveying techniques are essential for various tasks, such as identifying the levels of a land area with reference to a specific point, and mapping undulations and water bodies.There are two main types of surveying: plane surveys and geodetic surveys. Plane surveys assume the earth is flat,...

Surveys are essential for marking property boundaries near water bodies. Different types of surveys are defined, each with its own function. Land surveys mark the property boundaries, while route surveys determine the position of properties on nearby highways. Topographic surveys create maps by capturing the three-dimensional features of the land. Hydrographic surveys focus on the shapes of underwater areas and the movement of streams through the properties. Mine surveys determine the relative...

Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...
