Food safety.
Toxicological Factors Affecting Safety
would feed
Public Perception of Risk.
Steps in the Risk Assessment and Management Processes in
Relationship To Food And Its Components.
To develop appropriate food safety controls it is
particularly important to understand the link between the presence of a hazard that can be associated with a food.
Oral Toxicityl
Physiological and Anatomical Properties of the Tract
Gastrointestinal.
The digestive tube, also called the alimentary canal or tract
gastrointestinal begins in the mouth and extends to the anus.
Absorption Mechanisms.
Digestion is the conversion of food into absorbable substances in the body.
gastrointestinal tract
Role of the intestinal microflora in the toxicity of
Chemical compounds.
Most of the microorganisms, which inhabit with man, are
It is found in the gastrointestinal tract and its concentration increases as we go down towards the rectum.
Biotransformation And Toxic Elimination.
In the process of biotransformation and elimination of toxins
Factors Affecting Toxic Metabolism.
Drugs And Nutrients As Enzyme Substrates
metabolic.
Enzymes are biological substances (proteins, catalysts) that
They intervene in biological and chemical processes of the metabolism of living beings.
Main Manifestations Of Toxic Effects.
Some substances cause illness within minutes, while others
They take several hours, days or even weeks.
Hepatotoxic.
In the elimination and biotransformation of xenobiotics, the liver is exposed
to a large number of potentially toxic chemicals and metabolites
Nefrotoxicidad.
The kidney is particularly vulnerable to the action of toxins, since it is the
organ that receives the most blood supply per gram of tissue
Neurotoxic.
Neurotoxicity is a term that refers to those alterations
functional, structural and biochemical produced in the SN
hematotoxicity
Hepatotoxicity is the toxicological picture produced in the blood by a
noxious or toxic substance
Food Allergy And Intolerance.
Las reacciones adversas a los alimentos pueden deberse a una alergia
alimentaria o a una intolerancia alimentaria.
Concept and Historical Evolution of
Food safety.
Scope of Application, Requirements and Responsibilities Regarding
To Food Safety.
Food Toxicology Concept
The tolerable exposure limit represents the dose of a product (expressed
in mg/kg/day) that can enter the human body on a daily basis
Crises Related to Food Security
Crises related to food security encompass a broad framework
of possibilities.
Epidemiological evidence.
There is epidemiological, statistical, microbiological and
causation that support the causal relationship between the consumption of biscuit glacé and the occurrence of the outbreak
Rapid Alert System, Crisis Management and Emergency Situations
Emergency.
The Commission and the Member States, as members of the network, must
manage the revised system, called the Rapid Food Alert System
Toxicology of Natural Non-Nutritive Substances
In Food Of Seafood Origin. And Bacterial Toxins
Toxins From Molluscs.
Marine biotoxins are responsible for a significant number of
diseases associated with fishery products.
Neurotoxins.
Neurotoxins are called paralytic toxins or biotoxins.
that affect the central nervous system that cause muscular paralysis.
Saxitoxin and Other Related Toxins .
PSP-type toxins (saxitoxin and related compounds) and the
tetrodotoxin, compete with these compounds by binding to the sodium channel
Oxins Present in Fish.
The most common type of
fish poisoning in travelers is ciguatera fish poisoning
Treatment And Prevention
Treatment You can use activated carbon (1 g/Kg. of weight), which
adsorbs toxins that are still held in the digestive tracts.
General Etiology of Poisonings
you would feed
Symptoms And Diagnosis.
Food poisoning often begins with symptoms such as
nausea, vomiting, diarrhea, or fever.
General Treatment.
Most foodborne infections are mild and subside in 24 to 48
hours. There are, however, symptoms that reveal its severity.
.Toxicity Bioassays
They are an intensively used tool in
developed countries, in order to effectively and efficiently assess the acute and chronic toxic effects of pollution on living organisms.
Short and Long Term Toxicity Assays.
The new chemical substances that are going to be used as medicines,
food or agrochemicals must be previously evaluated
