Blood slaughterhouse

Area repellents are materials that are intended to keep animals away from a broad area. They include predator scent such as Hon or tiger manure, blood meal, tankage such as putrefied slaughterhouse waste, bone tar oil, rags soaked in kerosene or creosote, and human hair (84). Although few controlled tests have been mn on these materials in the past, more recent investigations of predator odors have shown promise (85). 

The first slaughterhouse in Denmark for organic meat was set up in 1994, for an organic pig farm nearby. It now produces organic cold meats and sausages. It advertises its products by informing the consumers that their products are made without additives, that all the meat is hand-cut, and that no mechanically recovered meat, blood plasma and extra meat proteins are ever used. 

Some of the research activities in blood substitutes use cow s blood without cells, which can be obtained from slaughterhouses. Another idea is perfluorohydrocarbons, which have a good solubility for oxygen and carbon dioxide, are free from immune-response problems, have no granules and easily go around partially clogged arterioles, and are metabolized in the body after a period of time (Feder 2001). 

The number of samples positive to clenbuterol from veal calves at farms and slaughterhouses during the period 1994-1995 is presented in Table 13.17. A decrease in the percentage of positive samples of urine and blood taken at both farms and slaughterhouses from 1994 through 1995 was observed. 

Most immunochemical methods published for the determination of sulfonamides in edible animal products, serum, and urine concern sulfamethazine analysis (Table 28.3). Early methods for screening sulfamethazine in swine blood (54) necessitated extraction of the antibiotic from the sample and application of long assay protocols that rendered them impractical for routine analysis in hog slaughterhouses. Later methods developed for the detection of sulfamethazine residues in swine serum (55), urine and muscle (8), and in milk (9) addressed the extraction and assay problems of previous methods. 

Serum samples. Bovine or porcine blood samples can be obtained from a local slaughterhouse or serum samples may be purchased.

In 1998, 3,678 samples were obtained from slaughterhouses (cattle, 1,171 pigs, 587 sheep, 242 poultry, 608) in addition feed samples (137) together with blood serum (185) and urine (285) were obtained from farms. Also in accordance with the revised EU Council Directive 96/23/EC fresh milk (210), eggs (150) and fish (5) samples were analysed. The result of this sampling and analysis programme was that 99.1% of samples were found not to contain detectable residues of veterinary drugs. In total 33 samples contained residues in excess of the MRL or action level.

Hyperfiltration serves the purpose of concentration of both plasma and hydrolysate separately. Flux data are very similar to those obtained on soy protein hydrolysates, and also the total economy of such process seems attractive. The main reason is that slaughterhouse blood in most cases is regarded as a waste product having no value, or even a negative value. 

The beer money is a tip for the slaughterhouse worker whose job will have to be interrupted for your benefit. He will fill the glass jar with fresh blood, close it. 

Most frequently, however, one obtains natural porphyrins from hemin, which is commercially available or can be produced on a kg scale from fresh blood from a slaughterhouse. Useful protoporphyrin derivatives are discussed in Section 2.4.2. 

Carboxypeptidase A (approx. 35 kDa MW, Sigma Chemical) functions both as a peptidase and an esterase it is in this latter mode that it can serve as a detector for cholinesterase inhibitors. Unlike the other enzymes such as AChE or BChE, it does not have a serine residue in the active site. TPPSi forms a complex with the enzyme and, upon challenge with the cholinesterase inhibitor eserine (physostigmine) in water, exhibits a change in the absorbance spectrum with a new peak and a marked increase in absorbance at 423 nm. This suggests TPPS, may not be completely displaced from the active site. For actual sensor operations, the use of an enzyme such as BChE or carboxypeptidase in place of (or in addition to) AChE will allow for potential identification of the analyte based on different specificities/sensitivities of the enzyme. Enzymes such as OPH, which are not readily available, may be difficult to obtain in large quantities the supply of AChE is often limited perhaps due to the capture of electric eels, while proteins such as BChE (from horse blood) and carboxypeptidase (pancreas) are more readily available from slaughterhouses. 

A woman employed in a poultry slaughterhouse developed dermatitis on the hand and forearms. A prick test with chicken heart and muscle was positive, and the patient had positive patch tests to chicken heart and liver (Beck and Nissen 1982). Two similar cases have been described (Harrington 1981). Cow and pig blood caused contact urticaria in two male slaughterhouse employees. An open test with the blood products was positive after 15-20 min, and the reaction subsided after about 1 h (Goransson 1981).
