A series of recent researchs focuses on the impact of climate change on agricultural production, land use, pollution and biodiversity, which implies the potential impactof climate change on food security is awidely debated and investigated issue. Nonetheless, the specific safety influence of food and feed for consumers has remained a less studied topic. This review identifies the various food safety issues from some literatures about climate change impacts on crop cultivation and livestock systems. According to general consensus, crop cultivation is recognized as a relatively susceptible partof the food and feed production sector thatcould be affected by climate change, variations in climatic parameters such as temperature, drought, precipitation, wind, and CO2levels are projected to have notable consequences on crops in terms of changes in the demand for fertilizer and pesticides, deterioration of the quality of soils,and expanding ranges of crop pests and altered transmission dynamics of insects, pests and plant diseases. Livestock production also could be heavily influenced by climate change, and the presence ofpathogenic bacteria in foods followingmore frequentextremeweather conditions, such as flooding and heatwaves. Therefore the challenges facing food securitywill pose new risks to human under the background of the global climate change.
