However, food-safety issues are receiving more attention now for several reasons. Furthermore, other potential chemical hazards may include substances that are safe or used in processing at certain levels but can cause illness or injury if consumed at too high of a concentration, such as sodium nitrite or antimicrobial solutions used in intervention steps. Your business also needs to consider radiological chemical hazards especially after the 2011 Fukushima nuclear incident that occurred in Japan post-earthquake and tsunami. At the stage of flour milling, there is the possibility of reducing the bacterial count for wheat. . The will need to evaluate in the hazard analysis the likelihood of the chemical to cause illness or injury. You may have heard of the most common one — Aflatoxins which are associated with peanuts, maize, tree nuts and certain spices.
Some grains contain natural chemical hazards, such as a variety of antinutritional components. Food can become contaminated by viruses when it is handled by an infected person who has practiced poor personal hygiene or when the food has come in contact with sewage which contains viruses. The value of chemicals for this purpose is the residual protection of grain during extended storage and transport. A common chemical hazard is using a chemical sanitizer with a much higher concentration than the regulatory standard. These hazards affect the product's safety. In contrast reports of food poisoning linked to bread itself rather than other ingredients; e. They can be introduced during food preparation or by consumers when using self-service facilities.
If you add too much you can then cause reactions in people who are sensitive to those food chemicals. Figure 1 summarizes the many aspects of food safety and quality control that must be coordinated in grain production. Jewelry should be limited to a smooth wedding band.

A physical hazard is any extraneous object or foreign matter in a food item which may cause illness or injury to a person consuming the product.
Following the nuclear reactor failure at Chernobyl Ukraine in 1986, food contaminated with radionucleides with long half-lives, such as cesium 137, is the major source of exposure for people living in this area. Physical Hazards Examples of physical hazards are foreign matter, including dirt and glass that accidentally get into food. Physical hazards Physical hazards include glass, packaging, jewellery, pest droppings, screws etc. These ergot bodies are recognizable in grain samples as black bodies sclerotia larger and longer than the normal grain length, but they break up easily, and of course, they disappear during milling.

Likewise, products that cluster with products of known high hazard level are likely to possess a greater potential to be associated with airway obstruction injury.
In such cases, there may be the need for various pretreatments to overcome the antinutritional effects of such compounds. One of the and most famous cases of an economically motivated hazard would have to be Melamine contamination in infant formula.
