Ecological food, also known as organic food and green food, means that in the production and processing of food such as grain, vegetables, fruits, livestock, fruits and edible oil, no synthetic fertilizers, pesticides and additives are used, and genetically modified seeds are not allowed. Certified by relevant certification bodies, it is indeed a pure natural and pollution-free safe and nutritious food. In foreign countries, organic food is a proper term with legal effect. After strict procedures, only those that meet the requirements can be labeled as organic food. Ecological food began in Europe and America. German "Der Blaue Engel" food, Italian "ecological agricultural products", American "organic food" and Japanese "natural food" all belong to the emergence of ecological food and ecological food, aiming at meeting people's consumption demand for high-quality, safe, pollution-free and nutritious food, protecting people's health and promoting a virtuous cycle of ecological environment.

Food and feed pollution sources

One is chemicals. There are many kinds of pesticides, heavy metals, additives, pigments, spices and hormones. Long-term detention is not easy to degrade or has serious harm to the body, so it is necessary to stop production and ban it; Customers should resist edible pigments and buy "clean food" without pigments; Natural biological products should be used in food and animal feed.

The ecological balance of biosphere is macro-level, and there is also a micro-ecological balance between animals and humans, such as the ecological balance of skin surface flora, oral flora and colon flora. Active microbial feed additive is to improve the ecological balance of colon flora by using the reproduction of beneficial microbial flora, produce beneficial secondary nutritional metabolites and competitively inhibit the growth of harmful microbial flora.

The second is the unreasonable use of antibiotics and antibacterial drugs. Medicine is not a nutrient, let alone a feed. If it is added to the regular feed of animals, it is easy to produce drug resistance after long-term feeding. If drug resistance occurs, it will not only fail when animals need treatment due to illness, but also bring disaster to human beings once drug-resistant bacteria infect human beings.

The third is intentional pollution. Processing and selling dead animals, dead birds, rotten food and feed, sewage irrigation, dirty production, adulteration and knowingly committing crimes all belong to killing people for money. The key is to strengthen the legal system, strictly enforce the law and crack down on localism to stop it.
