“…Foodstuff can also be contaminated with other toxic and non-degradable elements such as heavy metals. Heavy metals are defined as metallic elements with a density above 5 g/L [ 252 ]. Most metals toxic to human health are considered cadmium (Cd), lead (Pb), mercury (Hg), arsenic (As), and chromium (Cr) [ 253 , 254 ].…”

“…However, even in low concentrations, many physiologically essential for the human body heavy metals such as iron (Fe), zinc (Zn), copper (Cu), cobalt (Co), manganese (Mn), etc., can also be hazardous [ 254 ]. Sources of heavy metal pollution are several industries [ 252 ], pesticide and veterinary drug residues [ 255 ], packaging materials [ 256 ], technological incidents, and many others, which contaminate foodstuff and drinking water directly or by distribution in the environment and slow accumulation in food chains through polluted agricultural soils or intoxicated aquatic animals [ 257 ]. In case of prolonged ingestion, heavy metals accumulate in the human body, adversely affecting the nervous, cardiovascular, and reproductive systems, causing renal and lung diseases, hepatic damage, skin problems, and bone demineralization [ 258 , 259 , 260 , 261 , 262 , 263 ].…”

“…The most employed techniques for metal removal from contaminated industrial areas, waters, and the environment are chemical precipitation, ion exchange, membrane filtration, and solvent extraction [ 272 , 273 , 274 ]. Detoxification of heavy metals in vivo has been achieved with various chelating agents such as dimercaptosuccinic acid (DMSA) and ethylenediaminetetraacetic acid (EDTA), which promote the excretion of heavy metals [ 252 ]. However, the described chemical methods for both in vitro and in vivo metal detoxification have serious drawbacks limiting their application.…”

“…Environmental pH is another factor that strongly affects biosorption in LAB. Adsorption of Cd and Pb is very low at pH ≤ 3.0 and gradually increase above 3.0 to reach its maximum between pH 4.0 and pH 6.0 [ 252 ]. For example, the best rates of metal removal by Li.…”

Toxic ingredients in food can lead to serious food-related diseases. Such compounds are bacterial toxins (Shiga-toxin, listeriolysin, Botulinum toxin), mycotoxins (aflatoxin, ochratoxin, zearalenone, fumonisin), pesticides of different classes (organochlorine, organophosphate, synthetic pyrethroids), heavy metals, and natural antinutrients such as phytates, oxalates, and cyanide-generating glycosides. The generally regarded safe (GRAS) status and long history of lactic acid bacteria (LAB) as essential ingredients of fermented foods and probiotics make them a major biological tool against a great variety of food-related toxins. This state-of-the-art review aims to summarize and discuss the data revealing the involvement of LAB in the detoxification of foods from hazardous agents of microbial and chemical nature. It is focused on the specific properties that allow LAB to counteract toxins and destroy them, as well as on the mechanisms of microbial antagonism toward toxigenic producers. Toxins of microbial origin are either adsorbed or degraded, toxic chemicals are hydrolyzed and then used as a carbon source, while heavy metals are bound and accumulated. Based on these comprehensive data, the prospects for developing new combinations of probiotic starters for food detoxification are considered.

It is important to consider the health and well-being of birds in various production methods. The microbial makeup and function of a bird’s gastrointestinal (GIT) system may vary based on the bird’s food, breed, age, and other environmental conditions. Gut flora play a critical role in maintaining intestinal homeostasis. Environmental exposure to contaminants such as heavy metals (HMs) has been linked to a wide range of disorders, including the development of dysbiosis in the gut, according to many studies. Changes in the gut microbiota caused by HMs are a major factor in the onset and progression of these illnesses. The microbiota in the gut is thought to be the first line of defense against HMs. Thus, HMs exposure modifies the gut microbiota composition and metabolic profile, affecting HMs uptake and metabolism by altering pH, oxidative balance, and concentrations of detoxifying enzymes or proteins involved in HM metabolism. This chapter will focus on the exposure of chicken to HMs from their feed or water and how these HMs affect the immune system resulting in various diseases.
