Identification of Error-prone Cases in AFDC Quality-Control Corrective Action

States administering the Aid to Families with Dependent Children Program are giving a great deal of attention to quality-control efforts to reduce payment errors to federally established tolerance levels by July 1975. Under the threat of reduced federal financial participation for cases in error, states are implementing various methods of corrective action designed to insure that correct payments to cases are made. This paper presents a relatively simple, universally applicable method to identify error-prone cases at the state level so that corrective action may be taken before or immediately after a payment error occurs.

Pesticide residues and polychlorinated biphenyl levels in diets, urine, and fecal matter of preadolescent girls.

Summary and ConclusionsThe pesticide residue levels in the diets, urine, and fecal matter were not affected by supplementation of the diets with amino acids, ammonium citrate, or calcium lactate. Pesticide residues were found in all samples of the diets, urine, and feces. With the exception of the chlorinated cyclodienes, excretion of all residues was greater in the feces, suggesting the feces as the primary route of excretion. Excretion of the PCB's was predominately through the feces with 6.2% of the total excretion appearing in the urine. With the exception of DDT and its metabolites, excretion of residues was 9 to 12%. Maximum excretion of DDT and its metabolites was approximately 32%. PCB's were found in all eight diets analyzed. Four contained traces and four contained 200, 420, 580 and 840 μg/day/subject. The FDA has not yet established tolerance levels for PCB. Albert Kolbye, deputy director for the FDA's Bureau of Foods has, however, recently stated that PCB is regarded as moderately toxic but ce...

Fumigation with methyl bromide plus refrigeration to control infestations of fruit flies in agricultural commodities.

The minimum doses of methyl bromide (administered at the optimum temperature after a period of low-temperature storage), the minimum period of low-temperature storage, and the most effective combination of the 2 treatments were established for quarantine treatment of papayas, Carica papaya L., and avocados, Persea americana Mill., infested with the 3 Hawaiian tephritids, the Mediterranean fruit fly, Ceratitis capitata (Wiedemann); the oriental fruit fly, Dacus dorsalis Hendel; and the melon fly, D. cucurbitae Coquillett. Equations were used to approximate the separate effects of each of the subtreatments and of the combined treatments. The effective treatments projected about 32 survivors from a million eggs and larvae of the 3 species. Also, residues were determined in papayas and avocados after fumigation with methyl bromide, and tests were made with the minimum treatments to establish tolerance levels for residues in these commodities.
